KOA Speer Electronics is adding a high power 0402 size to their SG73P series of anti-surge, pulse precision thick film chip resistors. The SG73P1EW has a power rating of 0.25W with a TCR as low as ±100ppm/°C. This represents a 100% increase in power compared to the existing SG73P 0402 package. The SG73P1EW provides greater power and precision in a 0402 package size. 

The new SG73P1EW resistors offer a range of resistance values from 1Ω to 10MΩ and an operating temperature range of -55°C ~ +155°C. The pulse power SG73P1EW resistors are available with resistance tolerances of ±0.5%, ±1%, ±2%, and ±5%. The new SG73P1EW resistors are AEC-Q200 qualified.

The increased power capabilities of the SG73P1EW resistors enable engineers to downsize circuits and reduce the number of components required for their design. These anti-surge endured pulse power resistors provide high-precision control of high voltage circuits, making them an excellent choice for ECU use in automotive electronics, ADAS, industrial devices, and power supplies.
