Where the 0805 MLCC fits in the BOM
The EMK212BJ225KD-T is a Taiyo Yuden Series M multilayer ceramic capacitor in the 0805 footprint, the workhorse decoupling and SMPS filtering size for portable and dense PCB assemblies. Rated 2.2 µF at 16V with an X5R temperature coefficient, it covers the -55°C to +85°C band — suitable for industrial control boards and consumer electronics that run in heated enclosures or near thermal sources. The ±10% tolerance covers the class typical for bulk decoupling where absolute value matters less than impedance at the switching frequency. At 0.95 mm thick maximum, the part fits under low-profile ICs and alongside fine-pitch connectors without stacking constraints. Tape-and-reel packaging aligns with standard SMT pick-and-place runs on 0805 tooling — verify nozzle diameter matches the 2.00 mm × 1.25 mm body for consistent pickup force on high-speed lines.
