[t] is a measuring temperature indicated at °C that is not related to marking + or -.
** T.C.R. measuring temperature: o°C/+100°C.
*** Thermal time constant and thermal dissipation constant are values measured in stationary air and are typical values,
which are values of elements and vary with connecting or fixing methods.
**** Specified current is a current value that is used at reliability test under the condition of self heat-generation that can be disregarded.
Recommended measuring currents are 1mA for 100Ω and 0.1mA for 500Ωor 1kΩ.
For further information on packaging, please refer to Appendix A.
Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.
