Designed for demanding printed circuit board (PCB) mounting configurations, this component is housed in a robust 35 x 40 mm cylindrical aluminum can (T4 size code) with an insulated sleeve and an integrated safety vent at the base. Utilizing snap-lock terminals with a standard 5.8 mm lead length (bulk packaging option AA), it delivers exceptional mechanical stability and electrical performance across a wide operating temperature range of -40°C to +105°C. Optimized for low Equivalent Series Resistance (ESR) and high ripple current handling, this capacitor is rated for a working voltage of 63 VDC (with an 8 V surge capability scaling per series design rules, and specifically engineered for robust DC processing). It provides a guaranteed load life of 2,000 hours at its maximum rated temperature of +105°C under specified maximum ripple current conditions. Electrical parameters include a low leakage current (calculated as $I = 0.02CV$ or 3 mA, whichever is smaller, measured after 5 minutes at +20°C) and stable impedance-frequency characteristics supported by standard high-frequency ripple current compensation factors. The ELG series is ideally suited for power conversion and energy storage architectures, including switched-mode power supplies (SMPS), uninterruptible power supplies (UPS), general-purpose industrial power electronics, and high-capacity battery chargers. Fully compliant with RoHS directives and containing less than 0.1% lead in homogeneous materials, this component meets strict environmental standards without sacrificing thermal or electrical endurance. ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (21-Jan-2025) | | Product Range | ELG Series | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:4421410/) Snap-In Aluminum Electrolytic Capacitors **ELG, +105°C** # **Overview** # **Applications** The KEMET ELG aluminum electrolytic snap-in capacitors are designed with snap-lock terminals for printed circuit board mounting.

In Europe (RoHS Directive) and in some other geographical areas like China, legislation has been put in place to prevent the use of some hazardous materials, such as lead (Pb), in electronic equipment. All products in this catalog are produced to help our customers’ obligations to guarantee their products and fulfill these legislative requirements. The only material of concern in our products has been lead (Pb), which has been removed from all designs to fulfill the requirement of containing less than 0.1% of lead in any homogeneous material. KEMET will closely follow any changes in legislation world wide and make any necessary changes in its products, whenever needed. Some customer segments such as medical, military and automotive electronics may still require the use of lead in electrode coatings. To clarify the situation and distinguish products from each other, a special symbol is used on the packaging labels for RoHS compatible capacitors. Due to customer requirements, there may appear additional markings such as lead free (LF) or lead-free wires (LFW) on the label. # **Performance Characteristics** |**Item**|**Performance C**|**haracteristics**| |---|---|---| |Capacitance Range|560 – 82,000 µF|47 – 2,200 µF| |Capacitance Tolerance|±20% at 120|Hz/20°C| |Rated Voltage|6.3 – 100 VDC|160 – 500 VDC| |Life Test|2,000 hours (see conditions in T|est Methods & Performance)| |Operating Temperature|−40°C to +105°C|−25°C to +105°C| ||I = 0.02 CV (mA) or 3 mA|, whichever is smaller| |Leakage Current|C = rated capacitance (µF), V = rated voltage (|VDC).

KEMET's E aluminum electrolytic capacitors should not be stored in high temperatures or where there is a high level of humidity. The suitable storage condition for KEMET's E aluminum electrolytic capacitors is +5 to +35°C and less than 75% in relative humidity. KEMET's E aluminum electrolytic capacitors should not be stored in damp conditions such as water, saltwater spray or oil spray. KEMET's E aluminum electrolytic capacitors should not be stored in an environment full of hazardous gas (hydrogen sulphide, sulphurous acid gas, nitrous acid, chlorine gas, ammonium, etc.) KEMET's E aluminum electrolytic capacitors should not be stored under exposure to ozone, ultraviolet rays or radiation. **If a capacitor has been stored for more than 18 months under these conditions and it shows increased leakage current, then a treatment by voltage application is recommended.** # **Re-Age (Reforming) Procedure** Apply the rated voltage to the capacitor at room temperature for a period of one hour, or until the leakage current has fallen to a steady value below the specified limit. During re-aging a maximum charging current of twice the specified leakage current or 5 mA, whichever is greater, is suggested. © KEMET Electronics Corporation • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com A4021_ELG • 7/21/2023 4 Snap-In Aluminum Electrolytic Capacitors – ELG, +105°C # **Table 1 – Ratings & Part Number Reference** |**Rated**|**Surge**|**Rated**|**Case**|**DF**|**RC**|**LC**|**ESR**|**Prt Nmbr**| |---|---|---|---|---|---|---|---|---| |**Voltage**|**Voltage**|**Capacitance**|**Size**|||||**a ue**| |**(VDC)**|**(VDC)**|**120 Hz 20°C**
