The Keystone Electronics 1057TR is a surface mount coin cell holder designed for 20mm diameter batteries, such as CR2032 and CR2025. It securely holds a single battery with a polarized design that prevents improper insertion, ensuring correct polarity.
Key specifications include an operating temperature range of -50°C to 145°C, making it suitable for harsh environments. The contacts are made of phosphor bronze with gold plating (flash) for reliable electrical connection, while the base is constructed from glass filled LCP with UL 94V-0 flammability rating.
The holder is supplied on tape and reel (500 pieces per reel) with 44mm tape width and 20mm pitch, compatible with vacuum and mechanical pick-and-place assembly. The conductive polystyrene carrier tape meets ANSI/EIA-481 standards.
The operating temperature range is -50°C to 145°C.
Yes, the holder is marked as RoHS3 compliant.
It is supplied on 13-inch reels with 44mm tape width, 20mm pitch, containing 500 pieces per reel. Carrier tape is conductive polystyrene per ANSI/EIA-481.
It uses PCB surface mount with SMD (SMT) tab termination.
The holder is designed for 20mm coin cells, specifically 2032 series batteries (e.g., CR2032, DL2032).
Contacts are phosphor bronze with gold flash plating; base is glass filled LCP, UL rated 94V-0.
The specified height above board is 5.20mm (0.205"), though datasheet notes for an ultra low profile variant suggest 2mm; verify exact value.
