Hinweise
  1. When ordering, please specify packaging code: e.g. 2208NF-392XJRC.
  2. Inductance measured at 10.579 MHz using a Coilcraft CCF1506 test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286 impedance analyzer.
  3. Q measured using an Agilent/HP 4991A.
  4. DCR measured on Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture.
  5. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft CCF1506 test fixture.
Irms: Current that causes a 15°C temperature rise from 25°C ambient. Because of their open construction, these parts will not saturate.

Anschlüsse:

  • R = RoHS compliant matte tin over nickel over silver-platinum-glass frit.

Verpackung:

  • C = 7″ machine-ready reel. EIA-481 punched paper tape (1000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • D = 13″ machine-ready reel. EIA-481 punched paper tape. Factory order only, not stocked (3500 parts per full reel).

Löten/Reinigen

Feuchteempfindlichkeitsstufe (MSL):
1 (unlimited floor life at <30°C / 85% relative humidity)
Löttemperaturbeständigkeit:
Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
Vor dem Löten bitte den Beitrag Löten von Coilcraft-Bauelementen lesen.
Baugruppenreinigung:
Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
