PTC stands for “Positive Temperature Coefficient”. This thermostatic ceramic PTC heating element can be used to automatically maintain a constant temperature without special temperature controllers and temperature sensors like thermal resistors and thermocouples for temperature feedback.
This is a 5V 40°C module. We also offer a 100°C version.
It is suitable for both AC and DC regardless of polarity. The power capacity should be over the maximum dissipation power of the heating element, otherwise it cannot work properly.
When powered on, the PTC thermistor heats up by itself. The surface temperature of the constant-temperature heating PTC thermistor will maintain a constant value. This temperature is related to the constant temperature of the PTC thermistor. Multiple heating pieces of the same voltage are connected in parallel and installed side by side. The heating pieces cannot be installed overlappingly, otherwise, the heat will offset.
It can be used for instrument preheating and anti-freezing, solenoid valve anti-freezing, circuit board dehumidification, inkjet printer nozzle anti-freezing, and suitable for heating and dehumidifying small equipment that is automated and unattended all year round. R&D professionals and technical personnel can use it to heat applications according to their needs, such as incubators, electronic thermos bottles, holding cabinets, water dispensers, hand warmers and more.
