COIN CELL HOLDER FOR CR2450 DIP 180° BT-S-SN-B-CR2450-068
3 month ago
Product details
The CR2450 coin cell holder in DIP 180° configuration is a vertical, through-hole mounted battery holder specifically engineered for CR2450 lithium coin cell batteries . As a “DIP” (Dual In-line Package) component, this holder features two rows of pins designed to be inserted into plated through-holes on a printed circuit board and secured via wave or manual soldering. The “180°” designation indicates a vertical orientation, meaning the battery is inserted from the top and stands upright relative to the PCB surface. This vertical mounting style is widely adopted in PCB designs where horizontal board space is at a premium, as it utilizes vertical height rather than lateral footprint. The CR2450 battery itself measures approximately 24mm in diameter and 5.0mm in thickness, offering a typical capacity of around 620 mAh, making it an ideal power source for low-power, long-duration applications such as real-time clocks, memory backup circuits, IoT sensors, and industrial control systems .
The mechanical construction of the CR2450 vertical coin cell holder prioritizes secure battery retention, reliable electrical contact, and ease of assembly. The insulator housing is typically molded from high-performance engineering plastics such as PBT (Polybutylene Terephthalate) or LCP (Liquid Crystal Polymer), both of which offer excellent dimensional stability, chemical resistance, and UL94 V-0 flame retardancy ratings . LCP-based holders, such as MPD’s BV-2450-PC, are particularly valued for their high elastic modulus, strength comparable to aluminum, and resistance to shock and vibration—including certification for one-meter drop tests . The contact system utilizes phosphor bronze or nickel-plated phosphor bronze, materials chosen for their superior spring properties, low electrical resistance, and corrosion resistance . Many designs incorporate dual-pressure or bifurcated contacts that create an extra-tight connection with the CR2450 cell, preventing battery dislodgement under vibration or impact. Additionally, features such as polarity protection (polarized design), latch-assisting mechanisms for easy battery replacement, and auxiliary positioning pins for secure PCB mounting are common in premium holders .
The CR2450 DIP 180° coin cell holder delivers robust electrical performance suitable for demanding industrial and consumer applications. Typical electrical characteristics include a contact resistance of less than 100 mΩ, insulation resistance of 100 MΩ minimum, and superior dielectric strength—with some models rated at 1,100 volts per mil . The operating temperature range generally spans from -25°C to +85°C, with some high-performance variants extending to -40°C to +85°C or beyond . The through-hole termination style is designed for wave soldering processes, with recommended soldering temperatures ranging from 180°C to 220°C . The contacts are typically finished with nickel plating or tin plating (Sn100U" to Sn120U") over a phosphor bronze base, providing excellent solderability and corrosion resistance . The holder is designed for single-cell (1-position) configurations and features PCB pin terminations that provide strong mechanical anchoring to the board, eliminating the need for additional battery retention straps or dense foam padding—reducing both component costs and assembly labor .
The CR2450 vertical coin cell holder is deployed across a wide range of industries requiring reliable, long-life backup power or primary power for low-current devices. Primary application areas include industrial control systems (PLC modules, industrial computers, backup memory circuits), medical equipment (portable diagnostic devices, patient monitors), telecommunications infrastructure (base stations, routers, switches), consumer electronics (smart home devices, digital cameras, wearable technology), automotive electronics (TPMS sensors, keyless entry systems), and computing hardware (motherboard RTC backup) . Major manufacturers offering CR2450 vertical through-hole holders include MPD (Memory Protection Devices) with the BV-2450-PC, Yichi with the YC-2450-DIP, Renata with the HU2450N-LF and NL5077-LF series, Keystone with the 1068 model, and Takachi with the BV-50N series . The product is typically supplied in tray packaging, with bulk options available for prototyping or low-volume production . In summary, the CR2450 coin cell holder in DIP 180° vertical configuration represents a robust, space-efficient, and highly manufacturable interconnect solution that combines the long-duration power of the CR2450 lithium coin cell with the reliability of through-hole PCB mounting, making it an ideal choice for engineers designing backup power and low-current applications across industrial, medical, telecom, and consumer electronics sectors.
