When you’re designing systems that need current control, over-temperature protection, or self-regulating heating, you need more than just parts — you need precision, availability, and reliability.
That’s exactly what Advance Electrical Co. delivers with our high-volume stock of PTC thermistors. We’re a trusted B2B supplier for OEMs, industrial engineers, and electrical equipment manufacturers who require dependable protection components — fast.
A PTC thermistor (Positive Temperature Coefficient) is a temperature-sensitive resistor whose resistance increases as it heats up.
This makes it perfect for:
Unlike traditional fuses or relays, PTC thermistors reset themselves automatically once the temperature stabilizes — reducing manual servicing and improving uptime.
💡 Advance Electrical Co. Pro Tip: Use PTCs in your circuit as low-maintenance protection against surge and overheating failures.
