±1% Precision RT Metal Glaze High Voltage Resistors up to 33MΩ

1. Similar characteristic with metal film but resistance value can be as high as 33MΩ.

2. Metal-glaze elements provide high stable performance against environmental conditions and overload.

3. Resistant to heat, humidity & solvents.

4. Resistance tolerance 1%.

5. UL1676 approved RT 1/2W, RT 1W & 2W series (960KΩ–12MΩ).

The RT series metal glaze high voltage resistors are designed for electronic circuits requiring high resistance values and high-voltage handling capability. Featuring metal-glaze resistive elements, the series offers resistance values up to 33MΩ and rated power options of 1/4W, 1/2W, 1W, and 2W.

These high voltage resistors can be evaluated for high-resistance circuits in electronic equipment, subject to circuit design and electrical validation. The specified material characteristics include resistance to heat, humidity, and solvents. The technical data also lists load-life, moisture-proof load-life, and short-time overload tests to support engineering assessment under defined test conditions.

RT metal glaze high voltage resistors may be evaluated for high-resistance biasing, feedback, or voltage-sensing circuits in high-voltage power supplies. Confirm operating voltage, power dissipation, creepage distance, and applicable safety requirements before selection.

For high-voltage measurement equipment, these resistors may be considered for high-resistance circuit positions when supported by the circuit design. Resistance selection should account for voltage distribution, input impedance, and the required measurement accuracy.

In industrial control and electronic equipment, the RT series may be evaluated for high-resistance signal circuits or designated high-voltage nodes. Suitability depends on the actual operating conditions and validation results.

For high-voltage detection and high-resistance circuits in electronic test instruments, engineers can assess the RT series against the required voltage withstand capability, temperature rise, and environmental conditions.

When selecting an RT series metal glaze high voltage resistor, consider rated power, resistance value, operating voltage, ambient temperature, and load conditions together. For projects requiring ±2% resistance tolerance, confirm availability with the manufacturer before specifying this tolerance in the final bill of materials.
