BBC-S-SN-A-21700-121+Single Battery Holder For 21700 THM（1）~1

Huizhou Antenk Electronics Co., Ltd. manufactures BBC-S-SN-A-21700-121 through hole single 21700 lithium battery holder designed to stably fix one standard 21700 cylindrical cell and deliver consistent power supply to PCB electronic circuits. This battery holder adopts heat resistant PA46 nylon or equivalent Stanyl 46 plastic as insulating housing, matched with 0.30mm thick stainless steel contact springs finished with nickel underlayer plus standard tin plating, and buyers can upgrade to multiple gold plating grades ranging from gold flash to 30 micro inch gold to strengthen anti-corrosion ability and maintain low stable contact resistance under high temperature and humid working conditions. It adopts S-type 180 degree through hole mounting structure with dedicated standard PCB layout dimensions, supporting tray packing and bag packing two packaging options to fit manual assembly and small batch production demands. This single 21700 THM battery holder is widely applied in digital cameras communication equipment industrial control sensors smart home appliances electronic toys and precision measuring instruments. Operators must follow official PCB mounting dimension standards strictly during wave soldering, avoid excessive compression to prevent permanent elastic deformation of stainless steel spring contacts and store finished holders in dry storage space to avoid oxidation corrosion on tin nickel plating layers. Unlike competitors outsourcing plastic molding and metal terminal stamping Antenk implements full in-house production workflow covering self-developed precision mold fabrication stainless steel high speed stamping PA46 plastic injection molding tin 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 international environmental standards. We own massive self-developed plastic and metal precision molds, provide customizable plating and packaging solutions, offer round-the-clock professional technical support, and more than seventy percent of our battery holders are exported globally supported by our Guangdong Famous Trademark ANTENK and steady uniform mass production quality.
