Item Type: PTC Heating Element Material: Aluminum Alloy, PTC, Polyimide Film Size: Approx. 46x15x5mm / 1.8x0.6x0.2in Shell Material: Aluminum Shell Heating Material: PTC Ceramic Heaters Lead Wire Material: High Temperature Resistant Wire Use Voltage: 220V Surface Temperature: 230 Lead Wire Length: Approx. 15cm/5.9in Temperature Error: 10 Dry Burning Power: 17W Package List 5 x PTC Heating Element 1. Please follow the use of voltage for power supply, the use of other voltage may cause fire and product damage2. Please allow some error due to manual measurement 1CERAMIC THERMOSTATIC HEATERS: PTC heating element utilizes ceramic thermostatic heating technology to continuously output heat and automatically work at a constant temperature. 2INSULATION AND TEMPERATURE RESISTANT: Aluminum PTC heating element uses polyimide film to wrap the chip inside, which is insulated and temperature resistant. It is easy to use and highly reliable. 3APPLICABLE SCENARIOS: Ceramic thermostatic plate has no open flame, no redness, no toxic and harmful gas, suitable for use in humid environment, and can be used safely. 4LONG DRY BURN TIME: PTC quickly converts electrical energy into heat after power is applied and conducts it to the surface of the aluminum case within 10S, allowing for long dry firing. 5LONG SERVICE LIFE: PTC element can work 7x24 hours without interruption, providing a continuous heat source life of over 20,000 hours. Use voltage is 220V, surface temperature is 230, lead length is 15cm.
