Vishay Intertechnology has released a new series of micro-chip negative temperature coefficient (NTC) thermistors with a very small maximum body sensing diameter of 1.6 mm and fast response times of = 3 s in air and = 0.7 s 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.
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.
AEC-Q200-qualified with exceptionally high thermal shock resistance up to 2,000 cycles, the thermistors are intended for temperature sensing circuits in automotive temperature probes and control units, and in 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-coloured epoxy lacquer. The thermistors' flexible leads allow for easy mounting and assembly. The devices are compliant to RoHS directive 2002/95/EC, in accordance to WEEE 2002/96/EC, and fulfill ELV 2000/53/EC.
