1. When ordering, please specify

packaging code:

XFL4020-472MEC

Packaging: C = 7

″ machine-ready reel. EIA-481 embossed plastic

tape (1000 parts per full reel).

B = Less than full reel. In tape, but not machine ready.

To have a leader and trailer added ($25 charge), use

code letter C instead.

D = 13

″ machine-ready reel. EIA-481 embossed plastic

tape. Factory order only, not stocked (3500 parts per

full reel).

2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.

3. DCR measured on a micro-ohmmeter.

4. SRF measured using Agilent/HP 4395A or equivalent.

5. DC current at which the inductance drops the specified amount from its

value without current.

6. Current that causes the specified temperature rise from 25°C ambient.

7. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Designer’s Kit C436 contains 5 each of all values

Environmental RoHS compliant, halogen free

Terminations RoHS compliant tin-silver over copper. Other termina-

tions available at additional cost.

Irms Testing

Irms testing was performed on 0.75 inch wide × 0.25 inch thick

copper traces in still air.

Temperature rise is highly dependent on many factors including

pcb land pattern, trace size, and proximity to other components.

Therefore temperature rise should be verified in application

conditions.
