## **Ripple current capability** 

Due to the ripple current capability of the capacitor contact elements, the following current upper limits must not be exceeded in case of the absence of any forced cooling around the capacitor and its contact elements: 

|and its contact elements:|||||
|---|---|---|---|---|
|Capacitor diameter|51.6 mm|64.3 mm|76.9 mm|90 mm|
|IAC,max|45 A|66 A|74 A|89 A|



In the event of the availability of cooling (e.g. forced air around the capacitor body, forced air around the contact elements, capacitor base cooling by a heat sink) however above limits may be exceeded depending on the cooling conditions. For details please contact our sales offices.

Please note that there are design options which might not be available for each series. For further information refer to series data sheets. 

## **5.2 Low-inductance design** (M603) 

Low-inductance aluminum electrolytic capacitors offer numerous advantages for frequency converter design: 

- Voltage peaks caused by steep-edged pulses are significantly reduced. 

- Power semiconductors of a lower voltage class can be used. 

- Capacitor banks require fewer capacitors, which reduces the cost, weight and space requirements of frequency converters accordingly. 

The low inductance of the aluminum electrolytic capacitor with screw terminals is the result of various design improvements.

~~ae~~ **B43742, B43762 105** ° **C** 

Many of the data book types with diameter ≥ 64.3 mm can be ordered in low-inductance design with inductance approx. L = 13 nH. 

For low-inductance design the following deviation regarding case dimensions applies: 

d = 64.3 mm: l1 0.7 mm 

- d = 90.0 mm: l1 1.7 mm 

M5: Min. reach of screw = 9.0 mm 

M6: Min. reach of screw = 9.5 mm 

## **5.3 Capacitors with heat sink mounting** (M607, M657) 

As a large amount of heat is dissipated through the base of the case, the use of a heat sink connected to the capacitor base is the most efficient cooling method. For heat-sink mounting we offer a special optimized version of high-voltage capacitors with screw terminals in order to ensure an optimal heat transfer between the base of the case and the heat sink. The special design comprises: 

- Two thermal pads at the base. The first one (thickness 0.5 mm) closes the air gap at the base in the area which is not covered by the insulating sleeve and the second one (thickness 0.2 mm) ensures the electrical insulation of the case. 

- Minimized tolerance (±0.35 mm) of the overall length l1 of the capacitor to avoid unwanted mechanical forces on the terminals particularly when several capacitors are mounted between heat sink and bus bar. 

- Case with extra groove near the base for ring clamp mounting (recommended accessory B44030A0165-A0190B). The clamp ensures an optimal pressing of the case to the heat sink. 

- Most of the high-voltage data book types without threaded stud and for diameters ≥ 64.3 mm can be ordered in heat-sink mounting design. 

Please refer to chapter "General technical information, 5.2.2 Base cooling with heat sink". Regarding ripple current and useful life, please refer to chapter "General technical information, 5 Useful life".

## **5.5 PAPR terminal style** (M650, M657, M658) 

An aluminum electrolytic capacitor is a polar component that needs strictly to be mounted under correct polarity. With our PAPR terminal style ( **P** rotection **A** gainst **P** olarity **R** eversal) we offer an optional mechanical feature in addition to the visual polarity marking on the cover disk and the sleeve, which prevents from mounting in reverse polarity. 

The non-circular shape of the terminals and their arrangement perpendicular to each other enables the user to definitely prevent wrong mounting with respect to polarity (Poka Yoke).

## **Clamp mounting** 

Screw terminal capacitors without threaded stud and with a diameter ≥ 64.3 mm can also be mounted with ring clamps. Clamp mounting offers the following advantages: 

- Optimum heat transfer between capacitor base and board due to pressure contact High vibration resistance 

- Electrically insulated material 

## **Dimensional drawing** 

- 1) Length of screw depends on application. 

- 2) The screws have to be tightened uniformly and crosswise until the fixing part rests flatly on the board. 

- 3) Tubular rivets included in delivery package. 

General hints for mounting: If required, the four fixation parts can be cut out from the common carrier ring and mounted separately.

## **Cautions and warnings** 

## **Personal safety** 

The electrolytes used have been optimized both with a view to the intended application and with regard to health and environmental compatibility. They do not contain any solvents that are detrimental to health, e.g. dimethyl formamide (DMF) or dimethyl acetamide (DMAC). Furthermore, some of the high-voltage electrolytes used are self-extinguishing. 

As far as possible, we do not use any dangerous chemicals or compounds to produce operating electrolytes, although in exceptional cases, such materials must be used in order to achieve specific physical and electrical properties because no alternative materials are currently known. We do, however, restrict the amount of dangerous materials used in our products to an absolute minimum. 

Materials and chemicals used in our aluminum electrolytic capacitors are continuously adapted in compliance with the TDK Electronics Corporate Environmental Policy and the latest EU regulations and guidelines such as RoHS, REACH/SVHC, GADSL, and ELV. 

MDS (Material Data Sheets) are available on our website for all types listed in the data book. MDS for customer specific capacitors are available upon request. MSDS (Material Safety Data Sheets) are available for our electrolytes upon request. 

Nevertheless, the following rules should be observed when handling aluminum electrolytic capacitors: No electrolyte should come into contact with eyes or skin. If electrolyte does come into contact with the skin, wash the affected areas immediately with running water. If the eyes are affected, rinse them for 10 minutes with plenty of water. If symptoms persist, seek medical treatment. Avoid inhaling electrolyte vapor or mists. Workplaces and other affected areas should be well ventilated. Clothing that has been contaminated by electrolyte must be changed and rinsed in water.

## **Important notes** 

The following applies to all products named in this publication: 

1. Some parts of this publication contain **statements about the suitability of our products for certain areas of application** . These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We nevertheless expressly point out **that such statements cannot be regarded as binding statements about the suitability of our products for a particular customer application** . As a rule, we are either unfamiliar with individual customer applications or less familiar with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether a product with the properties described in the product specification is suitable for use in a particular customer application. 

2. We also point out that **in individual cases, a malfunction of electronic components or failure before the end of their usual service life cannot be completely ruled out in the current state of the art, even if they are operated as specified** . In customer applications requiring a very high level of operational safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by means of suitable design of the customer application or other action taken by the customer (e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or failure of an electronic component. 

3. **The warnings, cautions and product-specific notes must be observed.**

## **Important notes** 

7. **Our manufacturing sites serving the automotive business apply the IATF 16949 standard.** The IATF certifications confirm our compliance with requirements regarding the quality management system in the automotive industry. Referring to customer requirements and customer specific requirements (“CSR”) TDK always has and will continue to have the policy of respecting individual agreements. Even if IATF 16949 may appear to support the acceptance of unilateral requirements, we hereby like to emphasize that **only requirements mutually agreed upon can and will be implemented in our Quality Management System.** For clarification purposes we like to point out that obligations from IATF 16949 shall only become legally binding if individually agreed upon.
