1. Provides strong overcurrent protection and current limiting
2. Flameproof coating resistant to heat and solvents
3. Exceptional electrical and mechanical stability
4. High reliability for industrial applications
5. Compliant with RoHS and REACH standards

High-reliability, fire-resistant PTC thermistors are used in heater control and are specifically designed for heater control systems, offering superior performance.

Their overcurrent protection is particularly outstanding, providing strong current limiting under overload conditions to effectively protect sensitive components in the circuit from damage. PTC (Positive Temperature Coefficient) thermistors exhibit a significant increase in resistance as temperature rises. This characteristic allows them to self-regulate and automatically limit current in heater circuits, preventing circuit overload under abnormal conditions.

Size and Environmental Compliance

This PTC thermistor has a very compact size, suitable for various heating devices with limited space. Common sizes range from φ5mm to φ25mm, and custom sizes can be customized to meet specific application requirements, ensuring a perfect fit for the space constraints of different devices. Its fire-retardant coating provides additional protection, enabling the resistor to operate in harsh environments, withstand high temperatures, and exhibit strong resistance to common solvents.

 More importantly, this product fully complies with RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) standards, ensuring no environmental pollution during production, use, and disposal, meeting global environmental regulations.
