New Vishay LTO 150H Resistor Offers 75J Pulse Protection for EVs

Vishay Intertechnology has come out with a new heavy-duty resistor called the LTO 150H, and it’s built to handle tough electrical jobs, like those in electric cars, factory machines, and network systems. What makes this resistor stand out is its ability to absorb short, high-energy pulses, up to 75 joules in just 0.1 seconds, which means better protection for your sensitive electronics. 

This new resistor can also dissipate up to 150 watts of power when mounted on a heatsink, helping to prevent overheating and reduce the number of components needed. It works reliably in high-temperature environments (up to +175°C) and offers a wide range of resistance options, from 1 W to 2.2 kW, with high precision. Whether you're building battery management systems, on-board chargers, power tools, or even network gear, the LTO 150H is a perfect, space-saving choice that’s built to last. It's AEC-Q200 qualified and RoHS-compliant, making it a solid fit for modern, safety-focused designs.
