NTC thermistor targets auto probes, boilers, battery packs

Vishay Intertechnology Inc. released a series of micro-chip negative temperature coefficient (NTC) thermistors with a very small maximum body sensing diameter of 1.6mm and fast response times of ≤ 3s in air and ≤ 0.7s in oil. The NTCLE305E4xxxSB devices offer precise measurements over a wide temperature range, with accuracy of ±0.5?C (from +25?C to +85?C) and ±1.0?C (between -40?C and +125?C).

The three thermistors released provide designers options for electrical resistance values at + 25?C (R25) to meet the self-heating, voltage output, or noise suppression needs of their applications. The NTCLE305E4202SB, NTCLE305E4502SB, and NTCLE305E4103SB feature R25 of 2060Ω, 5,000Ω, and 10,000Ω, respectively (with other values available on request). Furthermore, these thermistors are AEC-Q200-qualified with exceptionally high thermal shock resistance up to 2,000 cycles, intended for temperature sensing circuits in automotive temperature probes and control units, and in industrial boilers, battery packs, and fire detectors.

The NTCLE305E4xxxSB devices are made of a micro NTC chip with two insulated solid silver-plated nickel wires which are coated with an ochre-colored epoxy lacquer. The thermistors' flexible leads allow for easy mounting and assembly.

Samples and production quantities of the new NTC thermistors are available now, with lead times of 10 weeks for large orders.
