With the new series PSJ2 and PSG4 current sensing resistors, KOA is expanding its range of Metal Plate Power Shunts. The four-pole design of the PSG4 in size 2725inch with welded copper connections makes a high current of up to 140 A possible. These low-resistance, non-inductive power resistors are available in the ohm values 0.5 […]

Now it is not necessary anymore to take a resistor in thinfilm technology if a resistor tolerance of 0,25% is used. Compared to KOA´s general purpose RK73-series, the new RK73G-series has an even better T.C.R of 50 ppm/K and its low resistance tolerance of 0,25% is ideal for precision designs. The RK73G-series in the new […]

In expansion of the WK73 series KOA offers now the WU732B. This low ohm resistor with longitudinal terminations provides at a size of 0612 and Tol. 1% a rated power of 1 Watt. The component produced in thick film technology is available in a resistance range of 10 mOhm to 100 mOhm. It is characterized […]

The SL-series from KOA is now with a power rating of 5 Watt available. The size of the SLN5 is 4528, the value range is from 5 to 9,1 mOhm (TCR 110 ppm/K) resp. from 10 to 200 mOhm (TCR 75 ppm/K). The wide temperature range extends up to 180ᵒC, the derating starts only at […]

The Japanese switch manufacturer Copal Electronics extends its product range by a Joystick Encoder suitable for operation panels for medical devices, broadcasting equipments, surveillance cameras and industrial machinery and equipment. The CJ25 series is a multi-function device with joystick, optical encoder and push switch integrated into one package. The diameter of the component is 25.4 […]

The TLR-series from KOA is now also with a power rating of 3 Watt available – on size 2512. The metal plate shunt (series designation TLR3AP) is offered with a resistance range of 0,5 to 10 mOhm. The dimensions in mm are 6,35 x 3,18 x 0,6 (LxWxH), which means a really low height. The […]

KOA has expanded its inductor portfolio by adding the KT11835 and the KTZ1030 transponder coils. Both coils are optimized for the high requirements of the automotive industry. Key features of the KOA transponder coils are the high mechanical reliability with 4 terminals, high Q and excellent sensitivity up to 75mV/μT in the low-frequency region around […]
