Vishay Intertechnology, a major producer of discrete semiconductors and passive electronic components, has unveiled a new line of radial-leaded, positive temperature coefficient thermistors.
Devices in the new TFPTL line comprise nickel thin film components with fast response time of below 2 s, positive temperature coefficients of + 4110 ppm/K, and superior stability over a broad range of temperatures between −55 °C and +150 °C.
The thermistors are offered in two sizes with 2.5 and 5.0 mm lead pitches. They provide designers a broad range of standard resistance values between 100 W and 5 kW at +25°C (R25), with tolerances of 1% to 5%. Non-standard resistance values and tolerances will be offered based on request. The TFPTL series devices demonstrate long-term stability (typical below 0.1 % drift) and high-temperature performance. These qualities make these devices suitable for temperature detection, measurement, compensation and control in consumer and industrial applications. Moreover, these devices can be used as a substitute for silicon-based temperature sensors.
Typical end products include consumer goods, power supplies, fan controls, motor drives, cooling and heating systems. Thermistors in the TFPTL line are UL-certified for the US and Canada. They feature a thin film ceramic chip comprising two tinned, copper-clad steel wire leads. They comply with RoHS Directive 2011/65/EU, according to WEEE 2002/96/EC, and epoxy-coated per UL 94 V-0.
