The X5R dielectric offers a practical balance between capacitance stability and volumetric efficiency, making this capacitor ideal for SMPS filtering where both high voltage rating and compact size are required. Taiyo Yuden's advanced multilayer technology achieves this combination of 1 \u00b5F at 50V in the 0402 form factor, enabling designers to save PCB space without sacrificing electrical performance in power supply applications.","working_principle":"The UMK105CBJ105KV-F uses a multilayer ceramic construction where alternating nickel electrode layers and barium titanate-based X5R dielectric layers are co-fired into a monolithic chip. The 1 \u00b5F capacitance at 50V is achieved through advanced thin-layer dielectric technology that maximizes the number of active layers within the 0402 footprint. In SMPS applications, the capacitor serves as a local energy reservoir and high-frequency noise filter. The X5R dielectric provides a stable capacitance profile over the -55\u00b0C to +85\u00b0C range, though designers should account for DC bias effects when operating near the 50V rating. The low ESR and ESL characteristics make it effective at suppressing switching noise in the 100 kHz to 10 MHz frequency range typical of SMPS circuits.","pin_description":"\n
