Family of lug thermistors now offers lead-free construction

Vishay Intertechnology's NTCALUG family of NTC lug thermistors is now available in a 100% lead (Pb)-free construction, claiming to make them the industry's first such devices to provide full RoHS compliance with no exemptions.

Manufactured with a 100% lead (Pb)-free ceramic die, the products contribute to a cleaner environment by excluding all hazardous substances that may cause issues throughout recycling and disposal. Moreover, when RoHS exemption 7c-I expires — which provides for lead (Pb) in glass — designers using the components will already be in full compliance.

The family includes various devices that give accurate temperature sensing in automotive, consumer, and industrial applications. Standard lug thermistors can continuously operate to +150C and long-term reliability of 5,000 hours (dry heat). Devices offering a nickel conductor and low profile closed ring tongue give a low thermal gradient, while mini-lug sensors are optimised for fast reactions in space-limited applications.

Offered in AEC-Q200 and cULus-recognized versions, devices in the family provide high insulation voltage ratings up to 2.7kVAC, a rugged construction, and simple mounting through their ring tongue terminals. The thermistors are provided with a range of customisation options to satisfy specific design demands in EV battery management systems, consumer appliances, 3D printers, welding equipment, HVAC systems, motor drives, alternative energy systems, power electronics, and more.
