Vishay Intertechnology (Malvern, PA) introduced a new series of high-power surface-mount multilayer ceramic chip capacitors (MLCCs) in the quad 0505 and 1111 case sizes. Designed for high-frequency RF applications in telecommunications, medical, military, and industrial equipment and instrumentation, the QUAD HIFREQ series features ultra-high Q > 2000, ultra-low ESR down to 0.01 Ω, and voltage ratings to 1,500 V. Based on an extremely stable ceramic dielectric and offering high serial resonant frequency (SRF) and parallel resonant frequency (PRF), the Vishay Vitramon devices released today are designed to provide reliable performance in critical applications such as filter and impedance matching networks, timing circuits, mixers, and oscillators. Features include:

  • Broad working voltages from 200 to 1,500 V.
  • Wide capacitance ranges from 1.0 to 1000 pF.
  • Tight tolerances to ± 0.1 pF.
  • Aging rate of 0 % per decade.
  • Operating temperature range of -55° to +125°C.
