DC blocking capacitors simplify part selection, says Vishay Intertechnology
Surface-mount multi-layer ceramic chip capacitors (MLCC) have been optimised by Vishay Intertechnology for DC blocking applications. The Vishay Vitramon DC blocking capacitors are characterised for common frequency bands ranging from 3MHz to 18GHz.
Manufactured in reliable noble metal electrode (NME) technology, the devices released are suitable for RF, Bluetooth, 5G and powerline communication circuits, military radios, infotainment systems, fibre optic lines, amplifiers, microwave modules and high frequency data links. The MLCCs block DC voltages eliminating the need for higher-cost broadband blocks, advised Vishay. They efficiently transmit the desired AC signal with less than 0.5 dB insertion loss across the selected frequency band.
The DC blocking capacitors cover the HF, VHF, UHF, L, S, C, X, and Ku frequency bands and offer resonance-free performance across the bands’ range. Offered in the 0402, 0603, 0805, and 1210 case sizes, the devices operate over a voltage range from 25 to 500V and a temperature range from -55 to +125 degrees C. S-parameters for the MLCCs are available for download.
Samples and production quantities of the DC blocking capacitors are available now, with lead times of 16 weeks.
Vishay manufactures discrete semiconductors and passive electronic components for the automotive, industrial, computing, consumer, telecommunications, military, aerospace and medical markets.
