Keystone Electronics Corp. SMT Contact-Matte Tin Plate 555

The SMT Contact-Matte Tin Plate, part number 555, is designed for secure mounting on printed circuit boards using a Snap-In design for through-hole installation. It accommodates battery sizes AAA, N, and A23, ensuring reliable spring tension that minimizes contact resistance. The clip is constructed from spring steel with a matte tin finish, which is suitable for lower soldering temperatures, making it ideal for applications involving temperature-sensitive components. The product features a flow-hole SMT solder tail design that enhances joint strength, and it is available on tape and reel for automated assembly processes. This component is particularly useful in applications requiring durability against shock and vibration while maintaining a low profile.
