Vishay – New radial-leaded PTC thermistors offer fast response times and high stability

A new series of radial-leaded, positive temperature coefficient (PTC) thermistors has been introduced by Vishay. Devices in the new TFPTL series feature nickel thin-film elements with positive temperature coefficients of + 4110ppm/K, fast response time of <2s, and high stability over a wide temperature range from -55C to +150C.

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

With their exceptional 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 they 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, says the company.
