Vishay LPSA 300/600/800 AEC-Q200 qualified high power resistors

The Vishay LPSA 300/600/800 are the first high power resistors on the market to be offered with the AEC-Q200 automotive qualification. Designed for direct mounting on a heatsink, the LPSA 300, LPSA 600, and LPSA 800 deliver high power dissipation and pulse handling capabilities to help designers reduce component counts and lower costs in automotive applications.

• High power dissipation enables designers to replace multiple lower power components with a single resistor in applications that use a heatsink and require space savings.
• High pulse capability allows designers to replace larger wirewound resistors to save board space
