Negative Temperature Coefficient (NTC) Thermistors

Temperature Compensation - JCR series

NTC thermistors specifically designed to heating devices (MOSFET's or transformers) as well as the system environment temperature protection.

Symbols in the PN:
  x - resistance tolerance: F=±1%, G=±2%, H=±3%, J=±5%, K=±10%, L=±15%, M=±20%
  y - B tolerance: F=±1%, G=±2%, H=±3%, J=±5%, K=±10%
