Wraparound and Single-In-Line,

Thin Film Nickel Temperature Sensors

Vacuum deposited nickel films are used to produce

temperature sensors with various characteristics. The small

size and small thermal mass of these devices result in a

quick response to changes in temperature.

FEATURES

• Conforms to the DIN 43760 specs in -60 °C to

+180 °C temperature range

• TCR: 6180 ppm/°C (between 0 °C and 100 °C) (3)

• Wide resistance range: 25

 to 2500 , TFS-S

25

 to 250 , TFS-W

• Packaging available: W/A, SIL

• 2 versions: SMD and through hole

• High stability (

and

< 0.2 % 1000 h at Pn at

150 °C)

• Material categorization: for definitions of compliance

please see www.vishay.com/doc?99912

Note



* This datasheet provides information about parts that are

RoHS-compliant and / or parts that are non RoHS-compliant. For



example, parts with lead (Pb) terminations are not RoHS-compliant.



Please see the information / tables in this datasheet for details

Notes

(1) Nominal value

(2) Between 0 °C and 100 °C

(3) The ohmic value RT at temperature T (°C) depends on R0 (ohmic value at 0 °C) according to the following equation:

RT/R0 = 1 + 5.485 x 10-3 T + 6.65 x 10-6 T2 + 2.805 x 10-11 T4

Example: A T = 100 °C



RT/R0 = 1.6180

TCR = ± 6180 ppm/°C



Vishay Sfernice can calculate ohmic value at T = 0 °C (as ohmic value mentioned in ordering procedure is at 23 °C)

(4) TFS-S is a single in line (through-hole)
