HFC221S30V220 Dipole Fatigue Resistant MOS Capacitor — 220 pF 30V Flip-Chip Ready In short: The HFC221S30V220 is a 220 pF, 30 V single-layer MOS capacitor built on high-resistivity float-zone silicon with a thermally grown SiO2 dielectric. It is designed for circuits that must hold a stable capacitance over many field and thermal cycles, and it is supplied with wafer-level micro-bump termination for flip-chip, bondwire-free assembly.
