400L 400SRichardson RFPD Inc. announced the availability and full design support capabilities for two series of precision tolerance, NP0 RF microwave capacitors from American Technical Ceramics Corp. (ATC).

The high-frequency, low-loss (Hi-Q) 400L Series and 400S Series capacitors feature a precision thin-film process that provides reliable and repeatable performance, industry-leading tolerances over a wide range of capacitance values, low ESR, and high series resonant frequency.

High electrical and thermal conductivity, and high stability over temperature, make these devices suitable for a variety of critical small- and large-signal RF and microwave applications, including filter networks, matching networks, Hi-Q frequency sources, tuning, coupling, bypass and DC blocking. They are built in SMT packages and are fully-compatible with high-speed automated pick-and-place manufacturing.

400L Series

  • EIA case size: 0402
  • Capacitance range: 0.1 pF to 68 pF
  • Tolerances: to +/-0.01 pF

400S Series

  • EIA case size: 0603
  • Capacitance range: 0.1 pF to 60 pF
  • Tolerances: to +/-0.02 pF

According to ATC, additional key features of the new capacitors include:
