Vishay LTO Series Power Thick Film Resistors

Vishay’s LTO 30, LTO 50, and LTO 100 are power resistors with a low inductance of less than 0.1 µH for use applications like power conversion, high-speed switching, and RF. They use low-profile TO-220 and TO-247 ceramic packages that attach directly to the heatsink, which improves heat dissipation and reduces board space.

The resistors can handle up to 100 W and are available in with resistance values from 10 mΩ to 1 MΩ, with tolerance as low as ±1% and a temperature coefficient of ±150 ppm/°C to keep resistance values stable across the wide operating temperatures of industrial and automotive applications. The resistors also offer excellent pulse handling, capable of withstanding energy up to 35 J in 0.1s. And if you’re designing for automotive applications, the LTO 100 series is also AEC-Q200 qualified.

  • Less than 0.1 µH inductance
  • TO-220, TO-247 ceramic packages mount directly to heatsink for improved heat dissipation
  • 30 W, 50 W and 100 W at 25ºC case temperature (heatsink mounted)
  • 0.010 Ω to 550 kΩ (LTO 30, LTO 50), 0.015 Ω to 1 MΩ (LTO 100)
  • Pulse handling energy up to 35 J in 0.1 s
  • 100 W LTO 100 resistors are AEC-Q200 qualified
