AR235RAQ Series

Chip Inductors for Critical Applications

AR235RAQ Series inductors offer up to 40% higher Q factor and 45% lower DCR than other 0402 series.
  • 0402 ceramic wirewound chip inductor
  • Up to 40% higher Q factor and 45% lower DCR than other 0402 series 
  • Very high SRF – as high as 28.8 GHz
  • Tight inductance tolerance
  • High temperature materials allow operation in ambient temperatures up to 155°C
  • Passes NASA low outgassing specifications
  • Standard tin-lead (Sn‑Pb) terminations ensures the best possible board adhesion. Note: Nickel barrier termination (tin-lead over tin over nickel over silver-platinum-glass frit, termination code P) is recommended for hand soldering applications.
