Negative Temperature Coefficient (NTC) Thermistors
Temperature Measurement Sensors - JSR series
NTC chips with lead wires coated by epoxy resin which are suitable to detect temperature in the air and general purpose applications.
Symbols in the PN:
x - resistance tolerance: F=±1%, G=±2%, H=±3%
y - B tolerance: F=±1%, G=±2%
