Description
Compact High‑Power Passive Heater – Precision Thermal Control in a Small Footprint
This passive heater module delivers stable, rapid heating with minimal power consumption. Constructed from a high‑quality alumina ceramic composite, it offers excellent thermal conductivity while maintaining mechanical robustness and resistance to thermal cycling. The design eliminates active electronics, reducing cost and complexity for systems that require a simple, reliable heat source.
Optimized for a wide operating voltage range, the heater achieves consistent temperature rises from as little as 0.5 V up to 12 V, making it suitable for battery‑powered or mains‑driven applications. Its low thermal time constant (<2 s) and high thermal resistance (≈10 °C/W) ensure swift response and precise temperature control, ideal for temperature‑sensitive processes such as polymer cure, calibration fixtures, or trimmed electronic assemblies.
- Key Spec 1: Power rating: 5 W (300 W per square inch) with instantaneous current limit up to 12 A
- Key Spec 2: Operating voltage: 0.5 V – 12 V DC; Temperature rise: 30 °C – 120 °C above ambient
- Key Spec 3: Thermal resistance: 10 °C/W; Thermal time constant: ≤2 s; Material: Alumina‑based ceramic composite (low thermal EMF)
- Common Use Case: Embedded temperature control in 3 D‑printer hot‑ends, automotive HVAC panels, portable sterilizers, and as a calibration element in laboratory instrumentation
