The S8421-45R from Harwin Inc. is an insulated SMT battery coin cell holder/retainer designed for Ø20mm batteries, specifically the CR2032 type. It features a surface mount design with SMD (SMT) tab termination, allowing for automated pick-and-place assembly. The holder accommodates a single coin cell and has an open style for easy battery insertion and removal.
Key specifications include a contact resistance of 30 mΩ maximum, insulation resistance of 1000 MΩ minimum, and a dielectric withstanding voltage of 220 V AC for 1 minute. The operating temperature range per the datasheet is -55°C to +85°C. The holder is constructed with a PPS (Polyphenylene Sulfide) moulding material with 30% glass fiber, rated UL94 V-0 for flammability, and phosphor bronze contacts with gold flash finish for reliable electrical performance.
The component is packaged in tape and reel conforming to EIA-481, with a quantity of 500 pieces per reel. The height above board is 5.30 mm. This holder is suitable for various portable and battery-powered applications requiring a reliable coin cell retention solution.
