Precision High-Voltage Resistors Ohmic range (400Ω - 30GΩ), up to 54kV operating voltage

I. Product Overview

The 22881 resistor series is specifically designed for applications such as voltage dividers, medical equipment, electrostatic devices, measurement equipment, and current-limiting devices. These applications require high stability, a low temperature coefficient of resistance (TCR), high ohmic values, and high short-term load capacity.

II. Product Features

• Resistance Value: 400 Ω ≤ 30 GΩ (reference model specifications).

• Resistance Tolerance: ±0.1% to ±10%.

• Temperature Coefficient: ±15 ppm/°C to ±200 ppm/°C (referenced from +25°C to +85°C, lower for special low ohmic value requirements).

• Max. Operating Temperature: -55°C to +225°C.

• Dielectric Strength: >1,000 V (at 25°C, 75% relative humidity).

• Load Life: 1,000 hours at rated power, with a maximum ΔR/R of 0.5%.

• Moisture Resistance: Maximum ΔR/R of 0.25%.

• Thermal Shock: Maximum ΔR/R of 0.25%.

• Encapsulation: Standard coating is silicone rubber (A). A 2-component epoxy coating (P) is recommended for oil-immersed and wave soldering applications (details upon inquiry). Other coatings can be provided based on special requirements.

• Lead Material: Copper wire, gold-plated.

• Weight: Depends on model number (details upon inquiry).
