Import Cermet Trimmer Potentiometer — Buy in Bulk from Supplier in China

The Cermet trimmer potentiometer from Ningbo Yujian Electronic Co., Ltd is a precision adjustable resistor designed for circuit calibration in electronic systems. It offers a nominal resistance range of 50 ohms to 2 megohms with a tolerance of ±10%, suitable for fine-tuning analog signals in sensitive applications. The component uses a cermet (ceramic-metal) resistive element, providing superior thermal stability and long-term reliability compared to carbon composition alternatives.

This trimmer is typically constructed with a 3.2 mm shaft diameter and a 6.3 mm square body, compatible with standard adjustment tools. The termination style is surface mount or through-hole, depending on variant, with solderable tin-plated copper leads. Standard operating temperature range is -55°C to +125°C, and the power rating is 0.1 W minimum. These are typical industry parameters for cermet trimmers used in commercial and industrial electronics.

End-users include manufacturers of automotive control modules, telecommunications equipment, medical devices, and audio mixers requiring stable, repeatable resistance adjustments. The product is commonly sourced in bulk for automated PCB assembly lines. Packaging is usually in tape and reel or bulk trays, with MOQs negotiable based on volume. Trade terms are typically FOB Ningbo or CIF, with lead times of 2 to 4 weeks confirmed after order placement.
