MLCCs in quad 2525Vishay Intertechnology (Malvern, PA) is adding to its QUAD HIFREQ series of high-power surface-mount multilayer ceramic chip capacitors (MLCCs) with a new device in the quad 2525 case size. The QUAD HIFREQ 2525 case device features  a high Q (> 4000 at 10 MHz, 1 pF), ultra-low ESR down to 0.018 Ω, and DC voltage ratings up to 3600 V. Based on an extremely stable ceramic dielectric and offering high serial resonant frequency (SRF) and parallel resonant frequency (PRF), the Vishay Vitramon device is designed to provide reliable performance in critical applications and offers a broad working voltage from 300 V to 3600 V and a wide capacitance range from 1.0 pF to 2700 pF. The device offers tight tolerances to ± 0.1 pF, a desirable aging rate of 0 percent per decade, and an operating temperature range of 55 °C to +125 °C. The MLCC is designed for:

  • High-frequency RF applications in magnetic resonance imaging (MRI) coils and generators.
  • RF instrumentation.
  • Telecom base stations.
  • Lasers.
  • Military communications systems.
