Thermistors are lead-free as Vishay reviews NTC lug thermistors
Believed to be the first devices to offer designers full RoHS compliance, with no exemptions, the NTCALUG family of NTC lug thermistors have a 100 per cent Lead (Pb)-free construction, Vishay Intertechnology has announced.
They are manufactured with a 100 per cent lead-free ceramic die, and contribute to a cleaner environment by eliminating all hazardous substances that could potentially cause issues during recycling and disposal said Vishay. When RoHS exemption 7c-I expires, which allows for lead in glass, designers using the components will already be in full compliance, it added.
There is a variety of devices available which deliver accurate temperature sensing in automotive, consumer, and industrial applications. Standard lug thermistors are capable of continuous operation to +150 degrees C and long term reliability of 5,000 hours (dry heat). Devices featuring a nickel conductor and low profile closed ring tongue to provide a low thermal gradient, Mini lug sensors are optimised for fast reactions in space-limited applications.
Available in both AEC-Q200 and cULus-recognised versions, devices offer high insulation voltage ratings up to 2.7kVAC, a rugged construction, and easy mounting via the ring tongue terminals. The thermistors are offered with a range of customisation options to meet specific design requirements in electric vehicle (EV) battery management systems, consumer appliances, 3D printers, heating ventilation and air conditioning (HVAC) systems, welding equipment, alternative energy systems, motor drives and power electronics.
Samples and production quantities of the lead-free NTCALUG family thermistors are available now, with lead times of 12 weeks.
Vishay manufactures a large portfolio of discrete semiconductors and passive electronic components used in automotive, industrial, computing, consumer, telecommunications, military, aerospace, and medical markets.
