Tinned copper braid, often specified under Aa 2350, plays a critical role in protecting sensitive electronics from electromagnetic interference (EMI). This article explores the key features, specifications, and applications of AA 2350 tinned copper braid, outlining its importance in various industries.
AA 2350: Meeting Military and Commercial Demands
AA 2350 refers to tinned copper braid manufactured in accordance with military specifications QQ-B-575 and A-A-59569. These specifications ensure a high level of shielding effectiveness against electrostatic interference, making AA 2350 suitable for demanding applications in both military and commercial sectors. The braid is constructed from woven tinned copper strands that meet ASTM-B-33 standards, guaranteeing conductivity and durability. Beyond EMI shielding, AA 2350 also provides protection against mechanical abrasion and stress, serving as a robust solution for grounding and cable protection. Importantly, this braid complies with RoHS standards, ensuring it meets environmental regulations.
Decoding AA 2350 Specifications
AA 2350 is available in a wide range of sizes and constructions to accommodate diverse application needs. The specifications detail critical parameters such as nominal inside diameter (ID), military specification designations (QQ-B-575 and A-A-59569), construction details (number of carriers, ends per carrier, picks per inch), AWG equivalent, nominal circular mil area (CMA), and nominal current carrying capacity.
