CR2032 3V Lithium Coin Battery with 2 Pins (Horizontal) Meet the compact, PCB-mountable CR2032 with pins you can trust for RTC/CMOS backup, embedded wearables, and ultra-low-power electronics. This horizontal 2-pin version ( CR-2032/HFN ) pairs the well-known 3 V CR2032 chemistry with solderable PC-pin tabs for secure, vibration-resistant installation—no loose holders, no intermittent contacts. Nominal voltage 3 V , typical capacity 225 mAh , –30 °C to 60 °C operating window, and proven Li-MnO₂ stability for long shelf and service life. Why engineers pick it ✅ Solder-ready 2 pins (horizontal) for low-profile PCB mounting; ideal for BIOS/CMOS/RTC memory backup, metering, and small IoT. 🔋 High energy density in a 20 mm × 3.2 mm cell; typical 225 mAh under 0.2 mA continuous drain. ❄️ Wide temperature performance (–30 °C to +60 °C for the assembled part—design for your environment). 🛡️ Stable Li-MnO₂ chemistry with low self-discharge for multi-year retention in standby roles. 🧩 Drop-in footprint for many horizontal CR2032 tabbed BOMs; PC-pin terminals for robust mechanical anchoring. Typical applications 🖥️ PC motherboards / CMOS backup ⏱️ Real-Time Clocks (RTC) in embedded systems & data loggers 🧪 Portable instruments, meters, sensors 🏷️ Small consumer devices & controls (remotes, keypads) 🩺 Healthcare and wellness electronics (where primary coin cells are specified) Integration notes ⚙️ Keep average drain ≤ 0.2 mA for rated capacity; plan for pulse loads with appropriate decoupling. 🔧 Horizontal orientation reduces profile; ensure pin pitch matches your footprint; verify standoff and keepout under the cell can. 🧪 Validate at temperature extremes; design to the assembly’s rating. 🔒 Observe coin-cell safety: keep away from children ; swallowing hazard and serious injury risk. Alternatives & when to use a holder If you need field-replaceable batteries, consider a CR2032 holder (PC-pin or SMT). Holders add height but simplify service. If you require wires or vertical mounting, select the appropriate tab orientation variant or a cabled coin-cell pack.
