## **Voltage Ratings for Telecommunications 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. 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 may 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 20Β°C still air. IT : Trip current: minimum current that will switch the device from low resistance to high resistance in 20Β°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 may 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 may 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 20Β°C still air.
- RMIN : Minimum resistance of device as supplied at 20Β°C unless otherwise specified.
- RMAX : Maximum resistance of device as supplied at 20Β°C unless otherwise specified. R1MAX : Maximum resistance measured one hour post-trip or post-reflow at 20Β°C.
- 250VAC interrupt products may help equipment pass ITU K.20, K.21 and K.45 recommendations and Telcordia GR-1089 Port Type 2 and 4 requirements.
- 600VAC interrupt products may help equipment pass UL60950, TIA-968-A and GR1089 Port Type 1, 3 and 5 requirements.
- Product is not currently available in a resistance matched or sorted option.
- ** R1MAX measured 1 hour post-trip or 24 hours post-reflow at 20Β°C.

## PolySwitch Telecommunications and Networking 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 βRxβ, where x = 1, 2, A, B, C, F, etc.) are supplied with resistance values that are within specified segments of the deviceβs full range of resistance.
## **Feature**
- Narrow resistance range.
## **Benefits**
- Can help provide greater flexibility for design engineers.
- Lower resistance devices can help provide increased loop length on line card designs.
- Higher resistance devices may help 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 0.5Ξ© of each other (1.0Ξ© 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 help reduce the tip-ring resistance differential, reducing the possibility of line imbalance.

## **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.
## **Notice:**
