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 4395A network
analyzer and an Agilent/HP 16092A 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. When
Irms
is greater than
Isat, Isat
is
the more critical specification, and
Irms
is shown in
gray
type.
See Temperature Rise vs Current curve below.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”
before soldering.
