SMT Power Inductor–ME3220

Document 380-1

1. Please specify

termination and packaging codes:

ME3220-104KLC

Termination: L = RoHS tin-silver over tin over nickel

over silver.

Special order:

T = RoHS tin-silver-copper (95.5/4/0.5)

or

S = non-RoHS tin-lead (63/37).

Packaging: C = 7

″ machine-ready reel. EIA-481

embossed plastic tape (2000 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 (7000 parts

per full reel).

2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using

Coilcraft SMD-A fixture in Agilent/HP 4284A impedance

analyzer.

3. DCR measured on a micro-ohmmeter and Coilcraft

CCF858 test fixture.

4. SRF measured using Agilent/HP 8753D network

analyzer and Coilcraft SMD-D test fixture.

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.
