Features
• Resettable switching device • Low current loss due to a low resistance in normal use • Protection against overcurrent and short circuit The mode of action is based on the PTC effect. In standard use, the resistance of the device is very low so that only a small power loss arises. In the event of an error, short-circuit or overcurrent, the resistance value of this device increases and protects the equipment. After eliminating the error and switching off the supply voltage, the device quickly returns to a low impedance state.
Application
• Ideal for low voltage power supply with a load to be protected up to a maximum voltage of 30V, such as: computers & peripherals, security and fire alarm systems, loud speakers, automotive applications, power transformers and general electronics.
