Vishay Launches Radial-Leaded PTC Thermistors with 4110 ppm/K Temp Coefficients, Response Time <2 s
Vishay Intertechnology Introduces New Radial-Leaded PTC Thermistors with Temperature Coefficients of + 4110 ppm/K, Response Time of < 2 s, and Wide - 55 °C to + 150 °C Temperature Range
MALVERN, Pa. - Vishay Intertechnology, Inc. (NYSE: VSH) 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 Ohm to 5 kOhm, 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 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.
Samples and production quantities of the new PTC thermistors are available now, with lead times of 10 weeks for larger orders. Pricing for U.S. delivery starts at $0.20 per piece. Follow PTC thermistors from Vishay at http://twitter.com/vishayindust.
