AR235RAP Series

Chip Inductors for Critical Applications

AR235RAP Series chip inductors feature higher inductance values than other 0402 ceramic chip inductors.
  • Exceptionally high Q factors
  • Outstanding self-resonant frequency
  • 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.

Notes
  1. When ordering, please specify termination and testing codes: e.g. AR235RAP471JPZ.
  2. Inductance measured using a Coilcraft SMD-F test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286A impedance analyzer or equivalent.
  3. Q measured using an Agilent/HP 4291A with an Agilent/HP 16197A test fixture or equivalents.
  4. SRF measured using an Agilent/HP 8753ES network analyzer and a Coilcraft CCF1232 test fixture.
  5. DCR measured on a Keithley 580 micro-ohmmeter and a Coilcraft CCF1010 test fixture.

Termination:
