*1 Please consult with us about the products equivalent to class B of JIS.
*2 Thermal time constant and thermal dissipation constant are reference values, which are values of elements and vary with connecting or fixing methods. Thermal dissipation constant is approx. 4mW/ under the surface mounting condition.
*3 The electricity which it is charged with in the element is moved to the range that rise in temperature due to a self-heat generation can be ignored.
Oridinarily recommended measuring currents are 1mA for 100
and 0.1mA for 500.
Approximate Expression for Resistance-Temperature Characteristics
-55 - 0 : RT=R0 {1+C1T+C2T2+C3 (T-100)T3}
0 - +125 : RT=R0 (1+C1T+C2T2)
RT : Resistance value at T
R0 : Resistance value at 0
T : Ambient temperature()
