Vishay Intertechnology has launched a new series of surface mount multilayer ceramic chip capacitors (MLCC) optimized for DC blocking applications.
The industry's first devices characterized by common frequency bands ranging from 3 MHz to 18 GHz, Vishay Vitramon DC blocking capacitors make it easy for designers to choose the right component for their application.
Manufactured with reliable noble metal electrode (NME) technology, the new devices are ideal for RF, Bluetooth, 5G and power line communications circuits; military radios; infotainment systems; fiber optic lines; amplifiers; microwave modules; and high-frequency data links.
In these applications, MLCCs block DC voltages – eliminating the need for higher-cost 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 the HF, VHF, UHF, L, S, C, X and Ku frequency bands and provide resonance-free performance across the entire band range. Offered in cabinet sizes 0402, 0603, 0805, and 1210, the devices operate over a voltage range of 25 to 500 V and a temperature range of -55° to +125° C. S-parameters for the MLCCs are available for download.
Samples and production quantities of DC blocking capacitors are now available, with lead times of 16 weeks.
