High-Performance Mosquito Repellent
A heat-activated repellent mat or liquid only releases active ingredient efficiently within a narrow temperature band — too cold and it barely works, too hot and it burns off too fast.
Repellent efficacy in these devices is a temperature-control problem as much as a chemistry problem — the heating element has to hold a consistent plateau for the active ingredient to release at a steady, effective rate.
Why PTC suits repellent devices
A small PTC heating chip warms a repellent mat or liquid reservoir to a stable target temperature, holding it there for consistent release throughout the device’s operating cycle — without a separate thermostat circuit in a product that’s typically small, low-cost, and battery or low-voltage powered.
Single-surface lead wire type
Small footprint and low-voltage operation suit compact, cost-sensitive consumer repellent devices.

- Consistent release rate from a stable plateau temperature, rather than a wide thermostat-cycling swing.
- Fast time-to-effective temperature after power-on.
- Low component count — no separate thermostat needed in a small, cost-sensitive product.
This is the same compact single-surface chip format used in other small consumer devices — see Heating Chip for the full lead-wire configuration range. PTCWORKS supplies chips to consumer device OEMs — contact our team with your target temperature and voltage.
