## **Voltage Ratings forTelecommunications and Networking Devices** 

For circuit protection telecommunications devices there are two applicable voltage ratings. These are **VMAX Operating** and **VMAX Interrupt** . To help understand the nature of these two different voltage ratings, the following definitions are provided: 

- **VMAX Operating** : For telecommunications devices this is the voltage used to obtain component recognition under UL1434. Most circuit protection devices are certified at 60V but can withstand higher VMAX Interrupt conditions as noted above. See Table T3 for its VMAX Operating. 

- ***VMAX Interrupt** : Under specified conditions this is the highest voltage that can be applied to the device at the maximum current. Devices have been designed to trip safely under higher power level cross conditions, as listed above, to assist equipment in meeting the appropriate industry conditions.

## **Notes:** 

IH : Hold current: maximum current device will pass without interruption in 20°C still air. IT : Trip current: minimum current that will switch the device from low resistance to high resistance in 20°C still air. 

- VMAX Operating : Maximum continuous voltage device can withstand without damage at rated current. This voltage is used for component recognition under UL1434. VMAX Interrupt : Maximum voltage that can be safely placed across a device in its tripped state. Devices have been designed to trip safely under higher level power cross conditions to assist equipment in meeting the appropriate ITU, UL60950, or GR1089 industry requirements. 

IMAX Interrupt : Maximum fault current device can withstand without damage at rated operating voltage. This current is used for component recognition under UL1434. Devices have been designed to trip safely under higher level power cross conditions to assist equipment in meeting the appropriate ITU, UL60950, or GR1089 industry requirements. 

PD : Power dissipated from device when in the tripped state in 20°C still air. 

RMIN : Minimum resistance of device as supplied at 20°C unless otherwise specified. 

RMAX : Maximum resistance of device as supplied at 20°C unless otherwise specified. R1MAX : Maximum resistance measured one hour post-trip or post-reflow at 20°C. 

* 250VAC interrupt products are designed to help equipment pass ITU K.20, K.21, & K.45 recommendations and Telcordia GR-1089 Port Type 2 & 4 requirements. † 600VAC interrupt products are designed to help equipment pass UL60950, TIA-968-A and GR1089 Port Type 1, 3 & 5 requirements. 

## **Warning :** 

- Users should independently evaluate the suitability of and test each product selected for their own application. 

- Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame. 

- These devices are intended for protection against damage caused by occasional overcurrent or overtemperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated. 

- Contamination of the PPTC material with certain silicone-based oils or some aggressive solvents can adversely impact the performance of the devices. 

- Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and mechanical procedures for electronic components. 

- PPTC devices are not recommended for installation in applications where the device is constrained such that its PTC properties are inhibited, for example in rigid potting materials or in rigid housings, which lack adequate clearance to accommodate device expansion. 

- Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above the rated voltage of the device.

**Note:** All temperatures refer to topside of the package, measured on the package body surface. 

## **Solder Reflow** 

- Recommended reflow method: IR, vapor phase oven, hot air oven. 

- Surface-mount devices are not designed to be wave soldered to the bottom side of the board. 

- Recommended maximum paste thickness of 0.25mm (0.010 in). 

- Devices can be cleaned using standard industry methods and solvents. 

## **Rework** 

- If a device is removed from the board, it should be discarded and replaced with a new device.

## **Wave Soldering and Rework Recommendations for Telecommunications Radial-leaded Devices** 

## **Recommended Wave Soldering** 

- Soldering temperature profile Temperature characteristic at component terminal with dual wave soldering 

## **Rework** 

- If a device is removed from the board, it should be discarded and replaced with a new device.

## **Resistance-sorted and Resistance-matched Devices** 

Most TCF, TRF and TS devices are available in resistance-sorted and/or resistance-matched versions. 

## **Resistance-sorted Devices** 

Resistance-sorted devices (part number suffix “Rx”, where x = 1, 2, A, B, C, F etc.) are supplied with resistance values that are within specified segments of the device’s full range of resistance. 

## **Feature** 

- Narrow resistance range. 

## **Benefits** 

- Greater flexibility for design engineers. 

- Lower resistance devices can allow for increased loop length on line card designs. 

- Higher resistance devices may provide greater protection by offering faster time-to-trip. 

## **Resistance-matched Devices** 

Resistance-matched devices are supplied such that all parts in one particular package (or reel) are within 0.5Ω of each other 

- (1.0Ω for TRF250-080T devices). Individual matched packages are supplied from the full resistance range of the specified device. 

## **Feature** 

- Tighter resistance balance between any two parts in a package. 

## **Benefits** 

- Resistance-matched devices may reduce the tip-ring resistance differential, reducing the possibility of line imbalance.

Founded in 1927 and headquartered in Chicago, Illinois, Littelfuse is a premier global manufacturer of circuit protection, power control, and sensing technologies. Widely recognized for pioneering the first small, fast-acting protective fuse, the company has grown into an industry leader whose highly reliable components are essential to modern industrial, transportation, and consumer electronics applications worldwide. At the core of the Littelfuse portfolio is an expansive and industry-leading range of circuit protection solutions. This encompasses a massive selection of traditional fuses, fuse holders, and resettable PTC thermistor fuses designed to safely interrupt overcurrent conditions. To defend against electrical overstress, Littelfuse also provides advanced transient voltage suppression (TVS) technologies, including thousands of specialized TVS diodes, TVS varistors, and gas discharge tubes (GDTs) that ensure robust defense against voltage spikes and environmental hazards. Beyond its foundational protection components, Littelfuse manufactures a diverse array of discrete semiconductors, sensors, and switching devices. Engineers rely on their high-performance thyristors, including TRIACs and SCRs, alongside power-efficient Schottky diodes and MOSFETs for demanding power control applications. Complemented by precision proximity sensors and highly reliable reed and solid-state relays, Littelfuse delivers the critical building blocks required for secure, efficient, and complete system design.
