Simplifying part selection for designers, the devices block DC voltages while efficiently transmitting AC signals with < 0.5 dB insertion loss

Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of surface mount multilayer ceramic chip capacitors (MLCCs) optimized for DC blocking applications. The first such devices in the industry, featuring common frequency bands ranging from 3 MHz to 18 GHz, Vishay Vitramon DC blocking capacitors make it easy for designers to select the right component for their application.

Manufactured using reliable Noble Metal Electrode (NME) technology, the devices launched today are ideal for RF, Bluetooth, 5G and electrical communication circuits; military radio stations; infotainment systems; optical lines; amplifiers; microwave modules; and high frequency data links. In these applications, MLCCs block DC voltages—eliminating the need for more expensive broadband blocks—while efficiently transmitting the desired AC signal with less than 0.5 dB of insertion loss in the selected frequency band.

DC blocking capacitors cover HF, VHF, UHF, L, S, C, X and Ku frequency bands and offer resonance-free performance across the band range. Available in sizes 0402, 0603, 0805 and 1210, the devices operate over a voltage range of 25 V to 500 V and a temperature range of -55 °C to +125 °C. S-parameters for MLCC are available for download.

Samples and production quantities of the DC blocking capacitors are available now, with lead times of 16 weeks.
