Negative Temperature Coefficient (NTC) Thermistors

Temperature Measurement Sensors - JDR series

Axial glass encapsulated NTC thermistors with high heat-resistance capability and high reliability.

Symbols in the PN:
  x - resistance tolerance: F=±1%, G=±2%, H=±3%, J=±5%
  y - B tolerance: F=±1%, G=±2%
