The MC22FF681J-F is a multilayer RF chip capacitor with a 2220 case size, rated for 1000 Vdc, and a capacitance of 680 pF with ±5% tolerance. It is constructed with a natural mica dielectric, offering high Q at UHF/VHF frequencies, high RF current handling with dV/dt of 20,000 V/µs, and thermal cracking resistance compatible with FR4 boards. The capacitor operates from -55 °C to +125 °C and is suitable for demanding RF applications such as power amplifiers, MRI coils, and tuned LCR circuits. Its dimensions are 5.7 mm length by 5.0 mm width, with a maximum height of 2.0 mm.
Rugged flexibility and compatibility with FR4 boards make Type MC and MCN capacitors ideal for use where other multilayer caps aren’t recommended because of cracking. The natural mica dielectric retains its high-Q to many megahertz, so higher frequency applications are limited by the circuit inductance, not the Type MC capacitor. Nonmagnetic Type MCN chips are available for MRI and other high frequency applications that often use more expensive porcelain ceramic chips.
