Product details

Huizhou Antenk Electronics Co., Ltd. manufactures BT-M-G0-R-CR2450C polarized SMT coin cell holder specially designed to firmly fix CR2450 round lithium batteries and form stable positive and negative polarized conductive circuits on printed circuit boards. This battery holder adopts UL94V0 grade glass filled LCP as high temperature resistant insulating housing, matched with 0.15mm thick phosphor bronze contact terminals finished with nickel underlayer plus standard gold flash plating, and clients can select multiple gold plating thickness options from 3 micro inch up to 30 micro inch gold to strengthen anti oxidation performance and maintain steady low contact resistance under long term high temperature and humid operating environments. It is M-type SMT surface mount polarized structural design with dedicated standardized mounting pad layout, supporting tray packing and tape reel packing two packaging modes to satisfy manual assembly and high speed automatic SMT mass production line demands. This polarized CR2450 coin cell holder is widely deployed in digital cameras communication equipment industrial control sensors smart home appliances electronic toys and precision measuring instruments. Operators must strictly align positive and negative polarity marks with official PCB layout during reflow soldering, avoid excessive bending force to prevent permanent elastic deformation of phosphor bronze springs and store finished holders in dry warehouse to avoid corrosion damage to nickel gold plating layers. Unlike competitors that outsource plastic molding and terminal stamping Antenk implements complete in house production workflow covering independent precision mold development phosphor bronze high speed stamping LCP injection molding nickel gold electroplating and full laboratory electrical and dimensional reliability testing, holding ISO9001 ISO14001 IATF16949 and UL E472792 certifications while fully complying with RoHS HSF and REACH global environmental protection standards. We own hundreds of self developed plastic and metal precision molds, provide customizable plating and packaging solutions, deliver round the clock professional technical support, and more than seventy percent of our coin cell holders are exported globally supported by our Guangdong Famous Trademark ANTENK and consistent uniform batch production quality.

0.15mm Thin Phosphor Bronze Contact Spring delivers consistent elastic clamping force and stable electrical conduction for CR2450 coin cell installation.

Glass Filled LCP CR2450 Insulating Base features UL94V0 flame retardancy and excellent heat resistance to withstand SMT reflow temperatures.

Polarized SMT CR2450 Battery Socket adopts distinct positive and negative positioning structure to prevent reverse battery assembly on PCBs.
