Please consult with us about the products equivalent to class B of JIS.

** 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/°C under the surface mounting condition.

*** Specified current is a current value that is used at reliability test under the condition of self heat-generation that can be disregarded.

Oridinarily recommended measuring currents are 1mA for 100

Ω and 0.1mA for 500Ω.
