PTC Thermistor
Features
1. Excellent thermal response due to small size
2. Suitable for countermeasure to short circuit test in safety standard.
3. Stable resistance after operation due to ceramic PTC.
4. Similar size is possible due to the large capacity for electric power.
5. Solid-state construction provides excellent mechanical vibration and impact resistance.
6. The SMD type's small size and light weight are helpful in miniaturizing the circuit.
