SMD 1206 epoxy-coated NTC thermistors for thermal protection and compensation in high-power applications.
The MF72-1206 Series epoxy-coated NTC thermistors are built with a 1206 (3.2 × 1.6 mm) surface-mount package, offering fast thermal response and higher power dissipation (200 mW). Featuring superior epoxy insulation and moisture resistance, these thermistors are ideal for power electronics, LED lighting, and industrial automation.
