1. When ordering, please specify
termination
and
packaging
codes:
SER1410-202MED
Termination: E
= 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 or equivalent.
4. SRF measured using an Agilent/HP 4395A network analyzer and an
Agilent/HP 16193A 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.
