Pulse Proof and Anti-Surge, High Power Thick Film Chip Resistors

Surge protection is becoming essential for all circuit designs. With the SG73-series, KOA offers a resistor series which has approx. 10 times higher pulse handling capability compared to standard flat chip resistors. Due to this outstanding pulse load capability these are suitable for protection of electronic circuits against extreme pulses and surges. These resistors are available with ±10 % or ±20 % resistance tolerance.

KOA has recently optimized the resistive material and the production process, and is now able to offer the SG73S, SG73P and SG73G-series also with tighter tolerances of ±1 %, ±0.5 % and ±0.25 %. mehr ...

KOA Product Update Information: High Current Jumper Overview

Thick film jumpers RK73Z and XR73Z: There are two main reasons for designers to use Zero-Ohm resistors (Jumper). The first is to avoid using an additional layer when two traces have to cross on the same side of the PCB, the second is to make different circuit configurations using the same PCB layout.

High current jumpers SLZ and TLRZ: In high power applications a conventional Zero-Ohm resistor may be not be able to handle the higher currents. The SLZ and TLRZ series from KOA can carry currents up to 44 A. mehr ...
