This is hot! Literally! Apply 5-12VDC and the stainless steel fibers in this heating fabric will warm up, creating a little heating pad. On one hand, it's just a gigantic resistor. On the other hand, it's flexible, light, and can be wrapped around a project. Originally designed for portable wearable heating pads, this fabric can be used for wearables, weather balloons, DIY-bio projects, thermal cycling for materials testing, etc. The temperature reached varies with voltage. Note that while the data/spec sheet says 15cm, its more like ~14cm long. Check the spec sheets in the Technical Details tab for a table of voltage/current/temperature outputs. You could PWM it with a power N-channel transistor if you want finer temperature control.We also have a smaller version of this heating padTechnical Details * Wire length: 5cm / 2" * Weight: 3.8g * Insulation: Polyimide film ('Kapton') * Fabric made of Polyester filament and micro stainless steel fiber * Power requirements: 5V DC up to 1A * Note: Datasheet for HF0515 reports length is 15cm but it is closer to 14cm. * Datasheet https://elecena.pl/product/22718066/electric-heating-pad-14cm-x-5cm 2023-03-07 https://elecena.pl/product/22718066/electric-heating-pad-14cm-x-5cm 2023-12-27 https://elecena.pl/product/22718066/electric-heating-pad-14cm-x-5cm 2024-09-19 https://elecena.pl/product/22718066/electric-heating-pad-14cm-x-5cm 2024-11-29 https://elecena.pl/product/22718066/electric-heating-pad-14cm-x-5cm 2024-11-30 https://elecena.pl/product/22718066/electric-heating-pad-14cm-x-5cm 2025-04-10 https://elecena.pl/product/22718066/electric-heating-pad-14cm-x-5cm 2025-08-05 https://elecena.pl/product/22718066/electric-heating-pad-14cm-x-5cm 2025-11-28 https://elecena.pl/product/22718066/electric-heating-pad-14cm-x-5cm 2025-11-29
