The BT-M-G0-R-CR498A is a specialized surface-mount coin cell holder designed specifically for the CR498A lithium coin cell battery. Manufactured by Antenk Electronics, this battery holder serves as a critical interface between the battery and the printed circuit board, providing a reliable and replaceable power source for a wide range of electronic devices. The model designation breaks down as follows: “BT” indicates Battery Holder, “M” likely refers to the mounting configuration (Surface Mount), “G0” represents a series or configuration code, “R” signifies Retainer or Reel packaging, and “CR498A” specifies the compatible battery type. As a surface-mount device (SMD), this holder is designed to be placed directly onto PCB surface pads and secured through reflow soldering, supporting high-speed automated assembly using pick-and-place machines. This makes the BT-M-G0-R-CR498A particularly suitable for high-volume manufacturing environments where consistent placement accuracy and assembly efficiency are critical requirements.
The BT-M-G0-R-CR498A coin cell holder features high-quality material selection optimized for reliability, durability, and manufacturing compatibility. The contact system utilizes phosphor bronze as the base contact material, specified as MAT”L 0.30(.012)TH”K Phosphor Bronze. Phosphor bronze is specifically chosen for this application due to its excellent spring properties, high fatigue resistance, and good electrical conductivity, ensuring consistent contact force over the product’s operational lifetime. The contacts feature a gold plating finish over a nickel underplating: the gold layer thickness ranges from 0.000003 to 0.000005 inches, applied over a nickel base of 0.000100 to 0.000150 inches. This gold-over-nickel plating scheme provides low contact resistance, excellent corrosion protection, and oxidation resistance, ensuring stable electrical performance even in challenging environmental conditions. The insulator housing is molded from heat-resistant Nylon, rated UL94 V-0 for flame retardancy. This material offers excellent mechanical strength, dimensional stability, and the ability to withstand the elevated temperatures of reflow soldering processes without deformation.
The BT-M-G0-R-CR498A is designed for Surface Mount Technology (SMT) assembly, featuring flat solder tails that are placed directly onto PCB pads and secured through reflow soldering. This surface-mount design offers several significant advantages over through-hole alternatives: it supports automated pick-and-place assembly, reduces manufacturing cycle times, eliminates the need for drilled PCB holes (freeing up board space), and provides consistent solder joint quality through controlled reflow profiles. The holder is specifically engineered for the CR498A lithium coin cell battery, ensuring proper fit, secure retention, and reliable electrical contact. Antenk offers a comprehensive range of battery holder termination options beyond SMT, including through-hole PCB leads, wire leads, and solder lugs, with custom lead lengths available upon request. The BT-M-G0-R-CR498A finds application across a diverse range of industries and products, including LCD displays, digital cameras, communication equipment, industrial control systems, computer and networking devices, automotive electronics, and precision instrumentation.
