AEC-Q200 qualified micro-chip NTC thermistors from Vishay

Vishay has released the NTCLE305E4xxxSB series of micro-chip negative temperature coefficient (NTC) thermistors with a very small maximum body sensing diameters of 1.6 mm, and response times of = 3s in air and = 0.7s in oil. The NTCLE305E4xxxSB devices provide 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 are NTCLE305E4202SB, NTCLE305E4502SB, and NTCLE305E4103SB. These thermistors offer designers a choice of 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 2060 Ohms, 5,000 Ohms and 10,000 Ohms respectively.

These thermistors are AEC-Q200 qualified with thermal shock resistance up to 2000 cycles and are intended for temperature sensing circuits in automotive temperature probes and control units, and industrial boilers, battery packs, and fire detectors.

The NTCLE305E4xxxSB devices consist of a micro NTC chip with two insulated solid silver-plated nickel wires that are coated with an ochre-colored epoxy lacquer. The devices are compliant to RoHS directive 2002/95/EC, in accordance to WEEE 2002/96/EC, and fulfill ELV 2000/53/EC.
