Keystone Electronics adds a new low-profile coin cell retainer for 2450 Coin Cells to round out its line of battery retainers. It measures .230 high by 1.0 deep by 1.385 wide including mounting tabs. This low-profile retainer is designed specifically for high-density SMT applications and features a "flow hole" solder tail that increases joint strength and remains visible for easy and reliable joint inspection. The dual spring contacts assure low contact resistance and are designed to hold the cell securely to withstand shock and vibration.
For ease of use and safety, polarity is clearly marked. Keystone’s retainers are balanced and lightweight for reliable pick-up and placement and are compatible for use with vacuum and mechanical pick-and-place assembly mechanisms. Retainers are manufactured using .010 nickel-plated phosphor bronze and are available in loose piece (#3008) and on tape and reel (#3008TR) with 250 pieces per 13.0 inch reel. The carrier tape is polystyrene that meets ANSI/EIA-481 standards, 56 mm wide with parts mounted on a 32 mm pitch.
