What are the GBR-182 Series High-Voltage Thick Film Resistors?
The GBR-182 is a 1W high-voltage thick film resistor built on a 96% alumina ceramic substrate (Al₂O₃), offering a higher power rating than its GBR-181 counterpart while retaining the same proven combination of ceramic mechanical stability, thick film precision, and full epoxy encapsulation. Designed for applications that require reliable operation under elevated voltage and sustained power dissipation, the GBR-182 serves both general-purpose and demanding professional environments where a standard 0.5W resistor would be insufficient.
The resistance range covers 0.1Ω to 20MΩ in E24 preferred values, addressing a wide spectrum of impedance requirements from low-value current sensing to high-impedance voltage division. Standard tolerance options of ±2% and ±5% are offered across the full range, with tighter tolerances down to 0.1% available upon request. The temperature coefficient of resistance (TCR) is ±50 ppm/°C for values above 1Ω and ±100 ppm/°C below 1Ω, ensuring consistent and predictable resistance behaviour across the operating temperature range of −25°C to +85°C.
The GBR-182 is fully encapsulated in epoxy resin using a fluidization process, sealing the resistive element against moisture ingress, mechanical stress, and environmental contaminants. This construction delivers the higher stability and lower noise performance characteristic of thick film technology compared to conventional carbon resistors, making the series well suited to circuits where long-term resistance drift or noise-induced signal degradation would compromise system performance. The combination of 1W rated power, high-voltage capability, and robust encapsulation positions the GBR-182 as a versatile component for both board-level and panel-wiring applications.
