Product Description
300-500 Ω PTC NTC Thermistor for IC Card Holder Protection MZ21 04BE
MZ21 04BE (300-500) Ω electronic meter IC card holder protection thermistor designed for prepaid electronic watt-hour meter applications.
IC Card Holder Protection PTC Thermistor
Protection Principle

The IC card holder protection thermistor prevents abnormal use of prepaid electronic watt-hour meter bayonets and protects against external static electricity, lightning strikes, strong electricity, accidental short circuits, and other attacks. It also enhances IC card reading/writing capability and extends the service life of both IC cards and card tables.
