Engineering Datasheet: SMT Battery Clip, Direct Footprint Replacement for Keystone 78
Securing heavy D cylindrical cells on FR4 boards demands massive retention force. Automated SMT assembly requires precise component positioning. The Jiatel JT-BC-D-KS78-SMT replaces the Keystone 78 directly. This clip features a 12.70mm wide flat mounting base. You can execute seamless board-level power integration. You do not need to alter existing PCB pad layouts.

- Test Instrumentation: High-drain portable devices requiring SMT stability.
Metallurgical Rigidity & Solder Joint Integrity
We stamp the JT-BC-D-KS78-SMT from high-tensile Spring Steel. This specific formulation guarantees absolute structural rigidity for heavy cells. The 30.23mm high gripping arms prevent cell dislodgement during mechanical shock. The clip will not yield under repeated D cell insertion cycles. We finish the assembly with high-density Nickel Plating. This maximizes solder paste wettability across the 15.39mm wide base. It eliminates the risk of cold solder joints on SMT lines.
NPI PCB Footprint Audit & SLA Directive
Board-level integration of heavy clips demands strict adherence to pad dimensions. Layout errors cause reflow misalignment and seating failures. Our engineering rules strictly prohibit unverified digital mockups. We execute structural footprint validation exclusively through official [Technical Datasheets]. We rely on dimensionally controlled [2D Footprint Specs].
