Huizhou Antenk Electronics Co., Ltd. (IATF16949, ISO9001, ISO14001 certified) presents the Coin Cell Holders For CR2032. This surface mount holder is specifically engineered for 20mm diameter CR2032 lithium batteries, providing a reliable power source for memory backup and low power devices. The holder features a low profile design with an installed height of only 2.8mm above PCB, making it ideal for ultra thin portable electronics. The housing is molded from high temperature UL94 V-0 LCP (Liquid Crystal Polymer), capable of withstanding 260°C reflow soldering without warpage. The positive contact is a dual finger stamped beryllium copper spring with selective gold plating (0.4 microns), while the negative side includes a wide retaining clip with an integrated anti vibration latch that holds the battery securely under shock and vibration. Key specifications include contact resistance below 25 milliohms, retention force of 70 to 100 grams, continuous current rating of 200mA (peak 400mA), and operating temperature range from -40 to +125 degrees Celsius. A clear polarity marking (plus sign) on the housing prevents reverse insertion, and an audible click confirms proper battery seating. RoHS and REACH compliant, UL recognized under E472792.
Applications include real time clock backup, IoT sensors, medical devices (glucose meters, digital thermometers), smart watches, fitness trackers, key fobs, and portable medical monitors. Usage method: the holder is supplied on tape and reel (1000 pieces per reel) for automatic pick and place. Solder the two SMT pads using standard reflow soldering with peak 260°C and stencil thickness of 0.12mm. After soldering, insert the CR2032 battery positive side up into the holder until the retaining clip snaps into place with an audible click. To remove, use a plastic pry tool to release the clip. Precautions: do not exceed 200mA continuous current, avoid reverse polarity, ensure PCB land pattern matches recommended footprint, operate within -40 to +125 degrees Celsius. Advantages over competitors: Antenks anti vibration latch prevents battery dislodgement under 10G vibration, a common failure in standard clips. The dual finger positive contact provides redundant electrical paths, ensuring uninterrupted power. Coplanarity is controlled within 0.08mm to eliminate tombstoning during reflow. Low MOQs of 1000 units with no tooling fees.
Production process: in house mold design, injection molding on 10 Japanese and Taiwanese machines using LCP resin, high speed stamping of dual finger and retaining clip on 9 presses, selective gold plating (0.4μm), automated assembly, 100 percent coplanarity and spring force inspection, contact resistance and insulation tests, 48 hour salt spray test, reflow simulation (260°C, 3 passes), and final QC with lot traceability. Free samples, 2D and 3D CAD drawings, and 24 hour technical support available. Contact Antenk for custom gold thickness and tape and reel packaging options.
