Vishay’s bigAMP thermistor receives UL certification

MALVERN, Pa. - Vishay Intertechnology, Inc. (NYSE:VSH), a semiconductor manufacturer with a market capitalization of $2.1 billion and a strong liquidity position reflected in its current ratio of 2.7, announced Tuesday that its SL2220007 bigAMP inrush current limiting negative temperature coefficient (NTC) thermistor has received UL certification.

The certification process, conducted by UL Solutions under File E209153, Volume 1, verified that the thermistor complies with UL Mark requirements for safety and performance.

"Achieving UL recognition for the SL2220007 is an important milestone that underscores our commitment to delivering high performance, safety-verified solutions," said Eric Rauch, VP Vishay Ametherm at Vishay Intertechnology.

The SL2220007 thermistor offers a steady-state current of 7 A while maintaining reliability and long-term performance. The component is designed for switching power supplies, AC motors, uninterruptible power supplies, industrial inverters, and variable frequency drives.

The device functions by absorbing high inrush current when equipment is first powered on, providing high initial resistance that quickly drops as steady-state current begins to flow. According to the company, it can handle up to 125 J of energy and 265 VRMS of voltage.

Samples and production quantities of the UL-recognized SL2220007 are currently available, according to the press release statement.
