DESIGN-IN SUPPORT

• Other resistance curves and tolerances are available on

request

• Consult Vishay for other lead length, other connector

crimping, or other features

FEATURES

• Fast time response for surface applications

compared to industry standard NTC lug sensors

• Reduced thermal gradient, due to the use of

small

dimensions

and

nickel

conductor,

allowing for an accurate surface temperature

measurement

• The sensor is not suitable for being permanently

in contact with water or liquids

• Small size connector and small lug ring tongue terminal,

allowing for temperature sensing at locations where only

limited space is available

• Optional connector, rated +85 °C, tin plated (e3)

• AEC-Q200 qualified available (grade 1)

• cULus recognized, file E148885

(UL category XGPU2/XGPU8)

• Material categorization: for definitions of compliance

APPLICATIONS

Thermistors used for surface temperature sensing and

control in:

• Computer equipment

• MOSFETS, IC’s, power electronics, heatsink temperature

control, LED emitter heat-sink control

• Consumer appliances

• Industrial equipment

• Automotive equipment

DESCRIPTION

Miniature

insulated

chip

thermistor

with

a

negative

temperature coefficient soldered to AWG#32 silver plated

nickel and insulated cables, and mounted inside a mini lug

tin plated copper barrel.

PACKAGING

Available in plastic bags.

CAUTIONS AND WARNINGS ON MOUNTING

AND HANDLING

Please read the special instructions:

• The sensor NTCALUG03A can be mounted by means of a

screw M2 (stud #1, #2), or a screw M3 (stud #3, #4) for

NTCALUG39A

• For the type without connector, the electrical connection

can be made by soldering, crimping, or welding

• For the type with connector, see section Mounting
