SG73G – Pulse Proof High Precision Resistor from KOA

25. January 2018

KOA now offers an advanced version of the proven SG73P-series. The Thickfilm SG73G-series is characterized by low resistance tolerance (0.5% or 0.25%) and a low TK (±50 ppm/K). This is possible because KOA optimized the resistive material and the production process. The SG73G-series has the same one-pulse characteristics as the SG73P-series. Until now three sizes […]

High precision thick film resistor from KOA

23. March 2016

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 […]
