Capacitors for decoupling, RF bypassing and DC blocking

13 June 2018 Passive Components

DLI, a brand of Knowles, offers the Bar Cap and Gap Cap families of capacitor for decoupling, RF bypassing and DC blocking applications.

Bar Caps are multiple decoupling/blocking capacitors configured in a single array. They are specifically designed for MMIC (monolithic microwave integrated circuit) circuits and RF bypassing requiring multiple capacitor applications, such as multiple decoupling or RF bypassing networks.

Featuring high Q and low inductance, Bar Caps can be integrated into an IC package to reduce bond wire lengths and leading to improved performance and simplified assembly. Operating at frequencies up to 30 GHz, they are ideal for DC blocking, RF bypassing, decoupling and GaAs ICs. They are supplied with 100 mil gold metallisation, with a nickel barrier layer, for wire bonding. Standard and custom package sizes are available to provide different capacitance values.

Gap Caps are series configured precision capacitors for microwave applications such as DC blocking and RF bypassing where their low insertion loss and high resonant frequencies make them ideal devices. This product’s unique recessed metallisation configuration eliminates the need for wire bonding up to 100 GHz and minimises the potential of shorting during epoxy or solder attachment – therefore reducing performance variations. Capacitance values are available from 0,2 pF to 800 pF and, operating at frequencies up to 30 GHz, the parts are ideal for DC blocking, RF bypassing, filtering, tuning and coupling. Customised solutions are available alongside catalogue products.
