KOA: Pulse-Proof High-Temperature Resistor

KOA now offers a resistor that combines pulse resistance with high-temperature characteristics. The HSG73P series (sizes 0402 – 1206) can be used in ambient temperatures of up to 200°C. Derating begins at 70°C based on ambient temperature, but only at 105°C or 125°C when considering the terminal part temperature. The rated power for size 0402 is 0.2 W, and for size 1206, 0.75 W is possible.

Furthermore, the component exhibits excellent pulse characteristics. In this regard, the HSG73P is comparable to KOA’s proven SG73P series. This means approximately 7 times higher pulse load capacity than comparable standard thick-film resistors. For example, for the 1206 size, a load of 270 W is possible for 10 µs. Of course, the HSG73P series also meets the requirements according to AEC-Q200.
