SMT Power Inductors–ME3215 Series
Document 432 -1
Document 432-1
Revised 10/15/08
1. Please specify termination and packaging codes:
ME3215-104K
LC
Termination: L = RoHS matte 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 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 (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.
