Key Features:

• SMT Ready Design – Features flat, outward-facing gold-plated contact tabs designed for direct surface mounting to printed circuit boards (PCBs), making it compatible with automated pick-and-place assembly lines.

• Gold-Plated Contacts – The stainless steel spring contacts are gold-plated to provide exceptionally low contact resistance, which is critical for handling the high current draws typical of 18650 lithium-ion cells.

• High-Temperature Housing – The black plastic chassis is molded from high-temp, UL 94V-0 rated Nylon, ensuring it will not warp or melt during standard infrared or convection reflow soldering.

• PCB Positioning Pins – The bottom of the holder features two molded plastic alignment pegs to ensure exact positioning and prevent shifting on the PCB prior to the soldering process.

Ideal For:

• Integrated power management on custom printed circuit boards (PCBs)

• Internet of Things (IoT) sensors and remote monitoring stations

• Portable medical devices and handheld test equipment

• Custom memory backup power supplies

• High-end consumer electronics requiring easily replaceable rechargeable power
