FEATURES

• Rapid response time on surface down to 2 s

• Suitable for narrow space applications

• High flexibility of the foil

• Insulated and humidity resistant

• A strain relief hole is included in the flex design

to avoid traction to the sensor head

• Gold plated terminations

• AEC-Q200 qualified

• Material categorization: for definitions of compliance

APPLICATIONS

• Consumer appliances and white goods

• Power supply (heat-sinks)

• Battery, displays, LED

• Industrial applications, robotics

•Boilers

• EV and HV batteries

DESCRIPTION

• Miniature NTC thermistor body mounted on an insulated

flex foil and topped with an insulating epoxy glob top

• For flat surface temperature sensing with low thermal

mass and rapid response time

MOUNTING

• The stiff flat sensing area can be pressed against a flat

surface by means of insulating material (silicone foam), by

spring force or by taping it with a double sided

temperature resistant adhesive

• The sensor contacts can be connected to a PCB

counter-connector or wire-to-wire connector or soldered

to conductors, or crimped with FFC connectors and ZiF

connectors

• A mating connector can be for example a 0.5 mm pitch

7 poles connector for FPC, with top contacts, accepting

4 mm FPC width, ZIF or non-ZIF versions. The poles

(1 + 2) and (6 + 7) can be used for the electrical

connection. For example in SMT versions : TE 1734839-7,

Hirose FH34S-7S-0,5SH(50), Molex 054550-0771, Molex

052745-0797

• Consult Vishay for other screw sizes, lead length,

insulation, connector crimping or other features

Note

• FFC/FPC = Flexible Film Circuit/Flexible Printed Circuit
