MS426RAT, MS446RAT

High-Reliability Air Core Inductors

MS426RAT, MS446RAT Series feature low DCR and excellent current handling capability.
  • Only 2 mm tall.
  • High Q over a wide range of frequencies.
  • High temperature materials allow operation in ambient temperatures up to 155°C.
  • Tin-lead (Sn-Pb) terminations ensure the best possible board adhesion.
  • Tin-lead (63/37) over copper terminations.

Notes
  1. When ordering, specify tolerance and testing codes: e.g. MS446RAT27NGSZ.
  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.
