Product Description

Product Description

This Square Low-Pass String (Antenna Filter) is a custom non-standard electronic component engineered for filtering applications, built with advanced precision through CNC turning and milling machining—a process that delivers exceptional dimensional accuracy of ±0.03mm, ensuring consistent performance in critical electronic systems. Constructed from a diverse range of high-quality, conductivity-optimized materials (including brass alloys like H62, C3712, C28000, HPb59-1/-2/-3, C3771, C3604, as well as CuZn39Pb3, C38500, and CZ121Pb3), each unit undergoes rigorous inspection via vernier calipers and micrometers to guarantee strict adherence to dimensional specifications. Its surface features a silver plating finish, selected for its superior electrical conductivity, corrosion resistance, and solderability—qualities that boost signal transmission efficiency while shielding the component from environmental wear, making it reliable for long-term use across varied operating conditions. Fully aligned with global quality and safety benchmarks, the filter holds ISO9001 certification , RoHS compliance, and Reach certification, ensuring it meets both performance and regulatory standards. Available in sizes spanning 1.5mm to 20mm and offered as an OEM/ODM solution to support tailored design requirements, this component has a lead time of 10 working days.
