PTC thermistors current protector, also called PTC thermistor resettable fuses, protect load against over-current, overload, short circuit. No need for replacement, resume protective function after a short cooling-down time.
Ceramic PTC (positive temperature coefficient) thermistors are used instead of conventional fuses to protect load, such as motors, transformers, or electronic circuit, against overcurrent for circuit protection. PTC thermistor protector not only respond to inadmissibly high currents but also if a preset temperature limit is exceeded. PTC thermistor over-current protector limits the power dissipation of the whole circuit by increasing their resistance and thus reducing the current to a harmless residual value. In contrast to conventional fuses, PTC thermistor resettable fuses do not have to be replaced after elimination of the fault but resume their protective function immediately after a short cooling-down time.
PTC Thermistor Over-current Protector Application
It applies in the over-current overload and short circuit protection of transformers, battery charger, switches, switch power supply, adaptor, meter, instrumentation, apparatus, electronic coils, control panels, air conditioner, automotive electron, etc.
Operating Principle of PTC Thermistor for Overload Over-current Protection
The operating principle is as indicated in the following. When a circuit is in the normal status, the current through PTC is lower than the rated current and PTC thermistor protector is in the normal state with small resistance value, which will not affect the normal operation of the protected circuit. In case of some fault in the circuit and the current is greater than the rated current, the PTC thermistor protector will become hot quickly and present a high resistance state, which sets the circuit relatively "off" to protect the circuit from damage. After the fault is removed, PTC thermistor protector will automatically restore its low resistance state and the circuit will resume normal operation.
Normally, when PTC thermistor is used as an overcurrent protection component, it is preferred to select maximum operating current, maximum operating voltage and proper specifications. Furthermore such factors should be taken into consideration as the dimensions of the components, rated zero-power resistance, operating temperature range, etc.
Linear PTC Thermistor (LPTC) resistance increases with the temperature rises in linearity, displays a virtually linear positive temperature coefficient over their entire temperature range, suitable in measurement and control system, temperature compensation. As the construction material is mainly semiconductor monocrystalline silicon, also called silicon temperature sensor, silicon thermistor, sometimes referred to as silistors. As the temperature coefficient is positive, the silicon temperature sensors exhibit fail-safe operation when a system overheats. Furthermore silicon is inherently stable, so silicon temperature sensor are extremely reliable and have very long operational lifetimes. Hermetically sealed glass package, axial leaded, 2 leads, can operate in high temperature and moisture environment. Linear PTC thermistor in small dimension, tightness, convenient for automatic installation.
