        Polymer PTC Resettable Fuses

        Safety approved and Global insurance

        PTC resettable fuses rated working voltage is 24V, 16V, etc., to maintain the current nominal 70mA-14A. Resettable fuse this series suitable for nickel-hydrogen batteries and lithium batteries. With a small, non-operating current, short response time, low resistance, high reliability, easy installation, can be used repeatedly and so on. And have some over-temperature protection, so that the battery is not abnormal operating temperature is too high, especially suitable for Li-ion and nickel-metal hydride and other more sensitive to temperature secondary (rechargeable) batteries.
