Feature: 1. Thermostatic Heating: PTC heating element utilizes ceramic thermostatic heating technology to continuously output heat and automatically work at a constant temperature. 2. Insulation and Heat Resistance: This 220V PTC heating element uses polyimide film to wrap the chip inside, which is insulated and heat resistant. 3. Fast Heating: PTC quickly converts electrical energy into heat after power on, and conducts to the surface of aluminum shell within 10s, so it can be dry fired for a long time 4. Long Lasting Use: The aluminum PTC heating element can work 7x24 hours without interruption and provide heat source continuously for more than 20,000 hours. 5. Applicable: PTC thermostat heating element has no open flame, no redness, no toxic and harmful gases, and is suitable for use in wet environments. Specification: Item Type: PTC Heating Element Material: Aluminum Alloy, PTC, Polyimide Film Heating Material: PTC Ceramic Heaters Lead Wire Material: High Temperature Resistant Wire Shell Material: Aluminum Shell Size: Approx. 35 x 15 x 5mm/1.38 x 0.59 x 0.20in Lead Wire Length: Approx. 15cm/5.9in Use Voltage: 220V Temperature Error: ±10℃.
