Feature:1. CERAMIC THERMOSTATIC HEATERS: PTC heating element utilizes ceramic thermostatic heating technology to continuously output heat and automatically work at a constant temperature.2. INSULATION 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.3. APPLICABLE 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.4. LONG 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.5. LONG 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.Specification:Item Type: PTC Heating ElementMaterial: Aluminum Alloy, PTC, Polyimide FilmSize: Approx. 46x15x5mm / 1.8x0.6x0.2inShell Material: Aluminum ShellHeating Material: PTC Ceramic HeatersLead Wire Material: High Temperature Resistant WireUse Voltage: 220VSurface Temperature: 230Lead Wire Length: Approx. 15cm/5.9inTemperature Error: 10Dry Burning Power: 17W.Package List:5 xPTC Heating ElementNote:1.
