Automotive power resistor

15 August 2018 Passive Components

Vishay has introduced a new AEC-Q200 qualified thick film power resistor featuring a clip mount TO247 package for direct mounting on a heatsink. For automotive applications, the Vishay Sfernice LTO 150 offers power dissipation of 150 W at a +45°C case temperature and an improved pulse handling capability.

The device provides higher power dissipation than competing devices in the TO247 package. This reduces the need for components to cool the resistor - saving board space, simplifying layouts and reducing overall solution costs. These benefits are amplified by the LTO 150’s energy handling, which allows designers to utilise fewer resistors.

Offering high temperature operation to +175°C and a broad range of resistance values from 0,03 Ω to 1,3 MΩ, the LTO 150 serves as the precharge or discharge resistor for inverters, converters and on-board chargers for electric vehicles (EV), hybrid electric vehicles (HEV) and plugged hybrid electric vehicles (PHEV). It can also be used in general industrial and military power conversion applications.

The RoHS-compliant device offers a non-inductive design, tolerances down to ±1%, and reliability test results with extensive temperature cycling from 1000 cycles and up.
