Low Resistance LTE RF Chokes

  • Designed primarily for use in two different cellular applications:
    As a filter element in bandstop and low pass filter.
    As a one pole filter, or RF choke, in the cellular bands.
  • Can also be used for ground-to-ground isolation
  • 55% reduced DCR for 220 nH part; 30% reduced DCR for 530 nH part

1 When ordering, please specify packaging code: e.g RA7305-AEW
Packaging: W = 7" machine-ready reel
EEIA-481 punched paper tape (2000 parts per full reel).
U = Less than full reel
In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter W instead.
2 Inductance measured at 7.9 MHz using a Coilcraft SMD-F test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286 impedance analyzer.
3 SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD-D test fixture.
4 DCR measured at 25°C on a Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
6 Irms: Current that causes a 15°C temperature rise from 25°C ambient. Because of their open construction, these parts will not saturate.
6 Ambient temperature range: −40°C to +85°C with Irms current.
+85°C to +10°C with derated current.
7 Storage temperature range: Component: −40°C to +100°C
Tape and reel packaging: −40°C to +80°C
8 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
9 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info..
