The 3022-2 from Keystone Electronics is a surface mount coin cell retainer designed for 20mm diameter coin cell batteries. It accommodates a single 3V cell and uses SMD (SMT) tab termination for easy soldering to a PCB. The retainer features phosphor bronze contacts for reliable electrical connection and a high-temperature nylon 46 insulator with UL94V-0 flammability rating, ensuring safety in various applications.
With a height above board of 5.08mm (0.200"), this retainer offers a low-profile design suitable for space-constrained assemblies. It includes battery release ports for convenient battery replacement. The insulator prevents shorting of the battery if installed incorrectly. The part is supplied loose (unassembled); a tape and reel variant (3022TR) is available for automated assembly.
Typical applications include portable electronics, battery-powered sensors, and IoT devices where a reliable 20mm coin cell interface is needed. The retainer is RoHS3 compliant, meeting environmental standards.
