About this product
A 30×30 cm silicone rubber heater pad for 3D printer heated beds, rated at 300 W on 220 V. It uses a nickel alloy heating wire wrapped in glass fiber and has an integrated NTC 100K (3950) thermistor for temperature control. The adhesive backing makes it easy to mount on most flat surfaces, and it can also be used in other heating projects.

Frequently asked questions
Does the heater need a separate temperature sensor?
No. The NTC 100K (3950) thermistor is already integrated into the pad. Your controller board firmware must be configured for a 100K NTC thermistor to read the temperature correctly.
Can I drive this 220 V heater directly from a microcontroller board?
No. The pad runs on 220 V mains, so it should be switched through a suitable relay or solid-state relay and protected by a fuse. Never connect it directly to a microcontroller or a low-voltage driver output.
