Micro MCH heaters for HNB devices
A single-cell device has to deliver a controlled temperature curve in a very small volume, on a tight power budget, thousands of times over. The heater circuit is where that is won or lost.
Designed around the temperature curve
We tune cold resistance and circuit distribution together so the element follows your control algorithm quickly and evenly, with low thermal mass and minimal standby loss between puffs.
- 3.7 V / 5 V / 7.4 V cell-compatible designs
- Micro footprints, thickness from 0.55 mm
- Graded heating zones and custom temperature profiles
- No inrush surge on a small Li-ion cell
- Ni tab, wire or FPC termination
Confidential development
Most HNB projects are developed under NDA with customer-owned tooling. We support iterative prototyping, small validation lots and controlled ramp to volume, with the circuit design kept exclusive to the project.
- NDA and tooling ownership
- Rapid prototype iterations
- Lot traceability, 100% electrical test
- RoHS / REACH material declarations

Questions buyers ask
Yes — that is standard for this application.
We normally run 2–3 circuit iterations before releasing a validation lot; the exact scope is agreed at project start.
