Import Et3006 Cermet Trimming Potentiometer — Buy in Bulk from Supplier in China

The ET3006 cermet trimming potentiometer is a precision surface-mount component designed for fine resistance adjustment in electronic circuits. It features a cermet resistive element, offering superior thermal stability and low noise performance compared to carbon or conductive plastic alternatives. The unit has a standard resistance range of 10 ohms to 1 megohm, with a tolerance of ±10% and a power rating of 0.125 watts at 70°C. Its compact 7.6mm x 7.6mm footprint enables integration into dense PCB layouts without compromising signal integrity.

The cermet construction combines ceramic and metal particles, providing excellent long-term stability under temperature cycling and humidity exposure. This makes it suitable for applications requiring consistent performance over time, such as calibration circuits in medical devices or industrial control systems. Typical termination is gold-plated nickel, ensuring reliable solderability and corrosion resistance. The rotational life exceeds 10,000 cycles, aligning with industry standards for trimmer potentiometers used in production tuning and field servicing.

This component is commonly sourced by manufacturers of telecommunications equipment, automotive sensor modules, and high-end consumer electronics requiring precise analog calibration. Buyers typically order in quantities of 500 to 5,000 units per batch, with packaging in tape-and-reel format for automated assembly. Lead times are generally 4 to 6 weeks ex-factory, and trade terms include FOB Shenzhen with payment via T/T or L/C. Confirm the exact resistance value and shaft type (slotted or cross-cut) before ordering, as these vary by batch.

Elecsoundled Electronics Co., Ltd. is a supplier based in Futian, Shenzhen, with a registered address at 7a, Hongfuge, Caifu Bldg., Caitian S. Road. The company is listed as an imported supplier with harbor trust tier, indicating verified export activity and logistics compliance. There is no public data on years in operation, workforce size, or production capacity. The listing confirms no direct response history, suggesting limited buyer engagement or automated communication protocols.

The supplier specializes in passive electronic components, primarily trimming potentiometers and variable resistors. It does not claim ISO certification, in-house R&D, or direct manufacturing of cermet elements. Its role appears to be sourcing and distribution rather than fabrication. Buyers should verify material composition and traceability through independent testing, as no documentation is provided on the origin of the cermet resistive layer.
