PART No. and DIMENSIONS

Part No.: SA103FW(B11)

Dimensions:

Electricall Property

Rated zero-power resistance: R = 10㏀ ± 1% (at 25℃)

B constant: B25/50 = 3950K ± 1%

* The B constant is calculated using the zero-power resistance values measured at 25℃ and 50℃.

Dissipation Factor(δ): δ = 3 mW/℃ (in air)

Thermal Time Constant(τ): τ = 12sec (max, in still air)

Operating Temperature: -40℃ ~ 120℃

Mechanical Property

Pull Strength:

When the static weight of 2kgf is applied to lead wire direcition for ten seconds after the sensor part of the product is fixed, the electrical property changes(△R, △B) are less than ± 1%.

Falling test: When the product is falling down to the board of wood three times at one meter height, the electrical property changes(△R, △B) are less than ± 1% and the exterior is not any changes.

Reliability Test of the Product

High Temperature Test: After the products are placed in a chamber of temperature at 110℃± 5℃ for 1000(+48,-0) hours, the electrical property changes(△R, △B) are less than ± 1%.

Low Temperature Test: After the products are placed in a chamber of temperature at -30℃± 5℃ for 1000(+48,-0) hours, the electrical property changes(△R, △B) are less than ± 1%.

Thermal Shock Test: After the products are located into an air chamber of temperature at -30℃ for 5 minute and then move into another air chamber of temperature at 90℃ for 5 minute for 1,000cycle, the electrical property changes(△R, △B) are less than ± 1%.

Damp Heat Test: After the products are placed in a chamber of temperature at 60℃± 2℃ and 95%RH(±5%) for 1000(+48,-0) hours. the electrical property changes(△R, △B) are less than ± 1%.
