Metal Glaze Resistor

Metal glaze resistors are fixed axial resistors made by depositing a metal oxide film onto a ceramic substrate and protecting it with a nonflammable coating. They deliver high resistance values in a small body and keep stable performance under high temperature, high voltage and humid conditions.

Why Choose YResistor

Quality Assurance Each batch is checked against the performance test conditions listed on this page, covering temperature coefficient, short-time overload, pulse overload, resistance to soldering heat, solderability, temperature cycling, load life in humidity, load life in heat and nonflammability.

Wide Specification Range The series is offered in power grades from 1/4W up to 5WS, with a resistance range of 1KΩ–75MΩ and tolerances of ±1%, ±2%, ±5% and ±10%. Standard-size bodies use a brick-red coating; small-size bodies use a gray-white coating, with a yellow ring added behind the precision color rings to distinguish types.

Expert Support Our engineers can help you select the right power grade, tolerance and derating curve based on your ambient temperature, working voltage and pulse profile. Send us the required resistance value and operating environment, and we will recommend a suitable grade.

Certification & Compliance The resistor surface is nonflammable: when loaded with AC voltage at 5, 10 and 16 times rated power for 5 minutes, no visible flame is produced.

Wholesale Pricing As a factory, we supply metal glaze resistors at wholesale prices with flexible MOQ. Contact us for quantity pricing, packaging options and delivery lead time.

Product Description

The metal glaze resistor is built on a ceramic rod with a metal oxide film resistive layer, protected by a nonflammable coating. It is designed for high resistance values in a small size and maintains stable performance under high temperature, high voltage and humidity. The rated power is derated linearly from 100% at +70°C to 0% at +125°C, with a rated operating ambient range of -55°C to +125°C. The temperature coefficient is ±500 ppm/°C, and the construction provides low noise and a low voltage coefficient for signal circuits.
