CA6 KV SMD A47K adhesive film

CA6 KV SMD A47K Adhesive Mylar Film

Product Overview

The CA6 KV SMD A47K adhesive mylar film belongs to the high-cost-performance series of sealed, dustproof trimmer potentiometers represented by Spanish brands such as PIHER and ACP. It features a cross-shaped housing and a shaftless design, combining a compact structure with excellent dustproof performance. This product is compatible with SMD automated mounting processes, has a resistance value of 47 kΩ, complies with RoHS/REACH environmental standards, achieves an IP5x dustproof rating, and exhibits a failure rate of ≤50 PPM in humid home appliance environments. It can effectively reduce the overall after-sales rate by 15%, making it an ideal component for white goods, automotive electronics, power tools, and other fields.

Technical Principle

This potentiometer is manufactured based on the carbon film resistor adjustment principle. Its core structure consists of a carbon film resistor layer printed on a glass-fiber-reinforced epoxy laminate, paired with a shaftless cross-slot design. External plastic knobs or screwdrivers drive the internal brush to rotate, achieving precise resistance adjustment. The shaftless design eliminates the protruding shaft structure of traditional potentiometers, fundamentally reducing the risk of shaft breakage caused by external impacts. Meanwhile, the sealed, dustproof housing effectively prevents dust and moisture ingress, ensuring stable operation under complex working conditions.
