Chip adjustable capacitor, with dimensions of 3.2*4.5*1.85mm (commonly known as domestic 3*4mm series adjustable capacitors or trimming capacitors)
The design concept of this product originates from the Murata TZC3 series, combining with the Korean SEHWA adjustable capacitors and a wide range of audiences, and finally produced and launched in the form of a micro-motion brand. After more than two years of research and development and optimization, this adjustable capacitor was launched in March 2021. After years of market accumulation, it has been maturely applied in multiple fields. Based on market and customer feedback, there has been no single case of failure to date. Currently, this product is jointly developed and directly sold by Huayi Electronics, which can provide technical support and other services.
