Vishay announced that its Vishay Ametherm SL2220007 bigAMP inrush current limiting negative temperature coefficient (NTC) thermistor has received UL certification under File E209153, Volume 1, from UL Solutions. The certification confirms compliance with UL Mark requirements for safety and performance.
Eric Rauch, VP Vishay Ametherm at Vishay Intertechnology, stated, “Achieving UL recognition for the SL2220007 is an important milestone that underscores our commitment to delivering high performance, safety-verified solutions. UL certification is a trusted benchmark worldwide. The UL Mark on the SL2220007 gives our customers added assurance that the thermistor meets the highest standards for quality, safety, and reliability for their most demanding power designs.”
The SL2220007 supports a steady-state current of 7 A and is designed for switching power supplies, AC motors, uninterruptible power supplies (UPS), industrial inverters, and variable frequency drives. It mitigates high inrush current at equipment startup by providing high initial resistance that decreases as steady-state current flows, handling up to 125 J of energy and 265 VRMS of voltage with minimal power loss.
Samples and production quantities of the UL-recognized SL2220007 are available now. Sales contacts are available at http://www.vishay.com/en/company/contacts/.
