Power resistors are used across the telecom sector for many applications ranging from wired telephone networks, Power supplies for Mobile telephony, Charging circuits in ubiquitous mobile phone chargers, Protection of Internet Routers and Wifi base stations. Wirewound resistors are used in inrush protection circuits in large power supplies and in smaller charger circuits too.
The size of the resistor can range from large high power and high current absorbing parts to low wattage but high surge resistant designs for protecting low current power supplies. Specially designed resistors have been used for board level lightning protection in large telecom networks. These resistors are custom designed to absorb large current surges for considerable duration and also for short high voltage pulses from the typical IEC specified test specifications in IEC 61000-4-5 document. We have a whole range of resistors which can be used in your telecom application.
