## Battery Holders 

Renata's comprehensive line of battery holders for lithium coin cells are available as horizontal or vertical versions with through-hole or SMT-design. As a leading producer and supplier of miniature batteries, Renata has created a holder program for highest quality requirements, such as low contact resistance, safe retention of the coin cells, and state-of-the-art solderability. 

## **Surface Mounting Technology (SMTU)** 

## **Features** 

Easy and fast replacement of the battery Designed for automatic "pick & place" mounting Safe retention of coin cell Automated battery mounting possible Clear separation of connections Protection against short circuits Protection against inverse polarity (polarized) Protection against leak currents Robust design Suitable for reflow soldering 

## **Specifications** 

Holder material: heat-resistant, glass fibre filled LCP Flammability rating UL 94 V-O 

Battery contacts: spring stainless steel AISI 301, nickel-plated throughout. Solder area tin-plated throughout, min. thickness 5μm. Contact resistance between contacts and the cell is less than 100 mΩ (measured through AC 1kHz; depending on the case material of the cell). 

UL recognition, file E218732 Operating temperature range: - 40/+100°C 

* Gold plated contacts for increased conductivity

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
