The PTC Heating Element – 5V 100°C is a self-regulating ceramic heater based on Positive Temperature Coefficient (PTC) technology. Designed for both AC and DC power, this PTC electric heater provides stable constant-temperature heating without the need for external temperature sensors or controllers. This thermostatic PTC heater is ideal for long-term, unattended applications requiring consistent thermal control in compact devices. Using a high-quality PTC heating element ensures reliability in every electronic project. Features AC or DC compatibility, no polarity requirement for the PTC electric heater Constant surface temperature: 100°C ±10°C with this PTC heating element Self-regulating PTC chip for safe, automatic temperature control in a thermostatic PTC heater Aluminum tube encapsulation for durability and heat insulation of the PTC heating element High temperature resistant silicone wires on the PTC electric heater Compact size, easy to integrate this PTC heating element into small enclosures Low power consumption, adjusts power automatically based on heat dissipation for the thermostatic PTC heater Technical Specifications Rated Voltage: DC/AC 5V PTC heating element power Power Consumption: Less than 5W for this PTC electric heater (actual usage depends on heat dissipation conditions) Surface Temperature: 100°C ±10°C in the thermostatic PTC heater (at 25°C ambient temperature) Dimensions: 25 x 20 x 5 mm (0.98 x 0.79 x 0.20 inches) PTC heating element size Encapsulation Material: Aluminum alloy for the PTC electric heater Wiring: Two-wire connection for thermostatic PTC heater setup Wire Type: High-temperature silicone insulated PTC heating element wiring Applications Instrument preheating with a PTC heating element Solenoid valve freeze protection using a PTC electric heater Circuit board dehumidification via thermostatic PTC heater Inkjet printer nozzle heating with PTC heating element technology Electronic thermos bottles, incubators, holding cabinets, hand warmers, water dispensers using a PTC electric heater Suitable for automated, year-round heating systems integrating a thermostatic PTC heater Power Supply Guidelines Use a 5V power source for the PTC heating element: switching power supplies, transformers, battery packs, or rechargeable batteries Ensure the power supply’s capacity is greater than the heater’s maximum dissipation power for the PTC electric heater For multiple elements, connect in parallel to increase total heating capacity of your thermostatic PTC heater system Decreased supply voltage may slow heat-up time for the PTC heating element but will not affect the final temperature Usage Warnings Do not immerse in water while using the PTC electric heater Do not use in flammable or explosive environments with a PTC heating element Avoid impact, piercing, or overlapping installation of your thermostatic PTC heater Must have sufficient heat dissipation to maintain stable operation of the PTC electric heater Package Includes PTC Heating Element – 5V 100°C x1
