1. Please specify termination and packaging codes:
MLC1550-452MLC
Termination: L = RoHS compliant tin-silver over copper.
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.
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.
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc
using a Coilcraft SMD-A fixture in an Agilent/HP 4284A
LCR meter.
3. SRF measured using an Agilent/HP4291A impedance
analyzer and a Coilcraft 16193 fixture.
4. DC current at which the inductance drops the specified
amount from its value without current.
5. Current that causes the specified temperature rise from
25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”
before soldering.
Specifications subject to change without notice.
