Vishay/Sfernice Automotive Thick Film Power Resistors offer high reliability and power/pulse capabilities in very compact packages. A high power-to-size ratio makes them a preferred solution in pulse handling applications. Offered in AEC-Q200-qualified DPak, D2Pak, and TO247 packages, these compact resistors can replace five to twenty chip resistors on a PCB.
LTO Power Resistors
Vishay / Sfernice LTO Power Resistors combine high power capability with strong thermal efficiency for demanding power electronics. Based on thick-film technology, these resistors offer excellent heat conduction, allowing for direct mounting on a heatsink and supporting continuous power ratings of 30W, 50W, 100W, and 150W. The surge performance is optimized for dynamic loads, with pulse absorption ranging from 20J/0.1s to 75J/0.1s, depending on the model. Precision laser trimming ensures stable and accurate performance across a wide resistance range from 0.01Ω to 1.3MΩ. The TO-220 and TO-247 packages are easily integrated into compact, high-power assemblies. The entire Vishay / Sfernice LTO lineup is AEC-Q200 qualified, guaranteeing automotive-grade robustness and long-term reliability. Typical applications include motor drives, snubbers and braking circuits, power conversion, and battery and energy storage.
LTO 150 Clip-Mount Power Resistors
Vishay / Sfernice LTO 150 Clip-Mount Power Resistors are AEC-Q200 qualified and offer a 150W power rating and tolerance ratings of ±1%, ±2%, ±5%, and ±10%. These power resistors feature a broad resistance range of 0.03Ω to 1.3MΩ, a non-inductive design, and are designed for clip mounting. Vishay / Sfernice LTO 150 Clip-Mount Power Resistors have an operating temperature range of -55°C to +175°C, a TO-247 package, and UL 94V-0 material.
