With Temperature Coefficients of + 4110 ppm/K, Response Time of < 2 s, and Wide - 55 °C to + 150 °C Temperature Range

 

MALVERN, Pa. — July 19, 2012 — Vishay Intertechnology, Inc. (VSH: NYSE) today introduced a new series of radial-leaded, positive temperature coefficient (PTC) thermistors. Devices in the new TFPTL series feature nickel thin film elements with positive temperature coefficients of + 4110 ppm/K, fast response time of < 2 s, and high stability over a wide temperature range from - 55 °C to + 150 °C.

Available in two sizes with lead pitches of 2.5 mm and 5.0 mm, the thermistors released today offer designers a wide variety of standard resistance values at + 25 °C (R25) from 100 Ω to 5 kΩ, and tolerances of ± 1 % and ± 5 %. Non-standard resistance values and tolerances are available on request.

 

With their excellent long-term stability (typical < 0.1% drift) and high-temperature performance, devices in the TFPTL series can be used for temperature measurement, sensing, compensation, and control in industrial and consumer applications. In addition, they can replace silicon-based temperature sensors. Typical end products include heating/cooling systems, motor drives, fan controls, power supplies, and consumer goods.

The TFPTL series thermistors are UL-recognized for the United States and Canada, and consist of a thin film ceramic chip with two tinned, copper-clad steel wire leads. The devices are compliant to RoHS Directive 2011/65/EU, in accordance to WEEE 2002/96/EC, and epoxy coated per UL 94 V-0.

 

Samples and production quantities of the new PTC thermistors are available now, with lead times of ten weeks for larger orders.
