Notes
  1. When ordering, specify tolerance, terminations and testing codes: e.g. ST446RAT27NGLZ.
  2. Inductance measured at 250 MHz on an Agilent/HP 4286A or equivalent with a Coilcraft SMD-A test fixture and correlation.
  3. Q measured at 250 MHz on an Agilent/HP 4291A or equivalent with a 16193A test fixture or equivalent.
  4. SRF measured on an Agilent/HP 8753ES or equivalent with a Coilcraft CCF1268 test fixture.
  5. DCR measured on a Keithley 580 Micro-Ohmmeter or equivalent.

Tolerance:

  • G = 2%
  • J = 5%

Termination:

  • L = Tin-silver over copper.
  • T = Tin-silver-copper (95.5/4/0.5) over copper. (Special order, added cost)
  • S = Tin-lead (63/37) over copper. (Special order, added cost)

Testing:

  • Z = Unscreened
  • H = Group A screening per Coilcraft CP-SA-10001
All screening performed to the document’s latest revision.
Custom screening also available.
