Engineering Bulletin: THM Insulated Retainer Integration (CR2032)
Integrating 20mm coin cells into high-density printed circuit boards requires rigorous short-circuit protection and absolute wave soldering coplanarity. The Jiatel JT-BC-3023 functions as a high-reliability, 1:1 mechanical drop-in alternative for the industry-standard Keystone 3023 insulated retainer. Engineered with a low-profile THM architecture and built-in battery release ports, it allows hardware designers to seamlessly execute board-level power integration while preventing accidental shorting of the battery within the holder.

- Smart Peripherals: Electronic lock mainboards requiring THM stability.
High-Temperature Insulator & Metallurgical Rigidity
To eliminate the risk of improper installation short-circuiting, the JT-BC-3023 integrates a precision-molded base utilizing High Temperature Nylon 46 (UL Rated 94V-0). This thermoplastic housing withstands extreme wave soldering thermal profiles without structural warping. The dual THM contacts are stamped from high-yield T=0.25mm Phosphor Bronze. This gauge provides absolute structural rigidity and exceptional elastic memory, preventing the retainer from leaning under wave soldering turbulence while ensuring continuous, low-resistance downward tension against the CR2032 cell.
NPI PCB Footprint Audit & SLA Directive
Board-level integration demands strict adherence to pin pitch (23.9mm) and drill hole diameter tolerances (2 x Ø1.85mm) to prevent THM misalignment. Our engineering directive strictly prohibits the deployment of unverified digital mockups for PCB layout confirmation. We execute structural footprint validation exclusively through official [Technical Datasheets] and dimensionally controlled [2D Footprint Specs].
To confirm that our THM insulated retainer matches your existing FR4 land pattern and CR2032 spatial constraints, mobilize our Senior NPI Engineering Team. Submit your board-level constraints directly to our technical desk: NPI Engineering Queue. We guarantee the dispatch of matched, production-ready PDF drawings within 12 working hours of form submission.
