AIRCHID PTC Heater Element — compact, selfregulating heating element for reliable low to midtemperature applications. Key benefits Selfregulating PTC element provides stable, consistent heat without complex control electronics — reduces the risk of overheating and simplifies design. Compact 35 x 21 x 5 mm size fits into tight enclosures and small instruments where space is limited. Durable aluminum shell improves heat transfer and mechanical protection for longterm use. Multiple voltage options for flexible system integration: 12V, 24V, 36V, 48V, 110V, 220V. Listing variant information: Color: 220V 230C 1035W (this variant is 220V with specification shown). Core attributes Brand / Model: AIRCHID PTC heater element Dimensions: 35 x 21 x 5 mm Heating type: PTC (positive temperature coefficient) constant thermostat / electric heating sensor Material: Aluminum shell for heat conduction and protection Available voltages: 12V, 24V, 36V, 48V, 110V, 220V Variant shown: Color: 220V 230C 1035W Power range: 10–35 W (as indicated for the listed variant) What makes it useful Constant thermostat behavior: The PTC characteristic means the element automatically reduces current as temperature rises, helping maintain a steady temperature without continuous active control. Small footprint and robust casing let you install it in incubators, instrument enclosures, sensor housings, and other compact assemblies where controlled heat is required. Aluminum shell speeds up heat transfer to the environment while protecting the internal element from mechanical damage. Suggested applications Incubators and small environmental chambers: maintain consistent internal temperatures for samples, eggs, or controlled experiments. Instrument and sensor warming: prevent condensation and maintain instrument performance in cold or variable environments. Enclosure temperature stabilization: keep electronic enclosures or battery compartments above minimum operating temperatures to improve reliability. Installation and compatibility notes Select the correct voltage variant (12V, 24V, 36V, 48V, 110V, or 220V) to match your power source and application. The PTC element is intended to act as a selfregulating heater; when designing a system, verify that the element's power characteristics (10–35W for the listed variant) meet your thermal requirements. Mount securely in contact with the surface or enclosure to maximize heat transfer; the aluminum shell aids conduction. Avoid immersing the element in liquids or exposing it to conditions beyond the product's intended use. Performance and reliability The PTC heating behavior provides a simple, inherent safety feature by reducing current as temperature rises, which helps prevent runaway heating in many applications. Aluminum housing offers a balance of light weight, heat conduction, and mechanical protection for consistent, longterm performance. If you need a compact, selfregulating heater element for incubators, sensor housings, or small enclosures, the AIRCHID 35x21x5mm PTC heater offers a straightforward, reliable solution. Ensure you select the correct voltage variant for your system (this listing: Color: 220V 230C 1035W).
