Flat MCH ceramic heating chips
Planar alumina plates with a tungsten circuit co-fired inside. The default choice when you need fast, even heat in a thin, electrically isolated package — and the series we customise most often.
Built around your assembly, not a catalogue
A heater chip is only useful if it fits the mechanical envelope and the control loop you already have. We design the printed circuit geometry, cold resistance and electrode position together, so heat lands where your product needs it instead of where a standard part happens to put it.
- Planar sizes up to 100 × 100 mm, thickness 0.7–2.0 mm
- Voltage 3.7 / 5 / 12 / 24 / 36 / 110 / 220 V, or to your rail
- Cold resistance 0.3–1,500 Ω with ±10% tolerance at 25 °C
- Nickel leads Ø0.25 / 0.3 / 0.5 mm, custom length, colour and terminal
- Optional holes, slots, chamfers and defined heating zones
Why buyers switch from PTC to MCH here
PTC elements are limited by their Curie point (typically ≤300 °C) and drift in power over time. A co-fired MCH chip reaches 200 °C in about 10 seconds, holds up to 45 W/cm² and keeps its resistance stable because the tungsten circuit is sealed inside dense ceramic, away from oxygen.
- No inrush current spike — kinder to your PCB and fuse
- Linear resistance–temperature curve for straightforward PID control
- Surface is not live: 4,500 V / 1 s withstand, leakage < 0.5 mA
- Lead-free and RoHS compliant, no Pb / Cd / Hg / Cr⁶⁺
Specifications
Questions buyers ask
Samples from 10 pcs. For production, typically 1,000 pcs per specification — flexible for pilot runs.
Yes. We provide a 2D drawing, resistance–temperature curve, dielectric / power test report and material declaration for every project part number.
