1. Please specify
termination
and
packaging
codes:
SER2014-202MLD
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: D
= 13″ 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 D instead.
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on
an Agilent/HP 4263B LCR meter or equivalent.
3. DCR measured on a Keithley 580 micro-ohmmeter.
4. SRF measured using an Agilent/HP 8753D network
analyzer and a Coilcraft SMD-D test fixture.
5. DC current at which the inductance drops 10% (typ)
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.
