Pulse-Resistant SG73P Series from KOA: Power-Up

Resistor manufacturer KOA is improving its pulse-resistant SG73P series. This specifically affects the 0402 (1E) size, which now has a power rating of 0.25 watts. This applies at a max. ambient temperature of 70°C or a terminal part temperature of 125°C. With this component, designated SG73P1EW, it is possible to replace a standard thick-film type in the 0805 size with the same power rating, for example.

The SG73P series features approximately 7x higher pulse power capability than a corresponding standard thick-film resistor. The component is offered in sizes 0402 to 1210, where the 1210 size can be loaded with up to 0.75 watts or even 1 watt (at a terminal part temperature of 95°C). Resistance tolerances of 0.5%, 1%, and 5% are offered, and the resistance range extends from 1 ohm to 10 Mohm. Naturally, the SG73P series also meets the requirements according to AEC-Q200.
