1. When ordering, please specify
termination
code:
SER2211-333MED
Termination: E
= RoHS compliant matte-tin over nickel over phos bronze.
Special order:
Q
= RoHS tin-silver-copper (95.5/4/0.5)
or
P
= non-RoHS tin-lead (63/37).
Packaging: D
= 13″ machine-ready reel. EIA-481 embossed plastic
tape (200 parts per full reel). Quantities less than
full reel available: in tape (not machine ready) or with
leader and trailer ($25 charge).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/
HP 4284A or equivalent.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using an Agilent/HP 4391A impedance analyzer and
an Agilent/HP 16193A test fixture.
5. DC current at which the inductance drops the specified from its value
without current.
Click for temperature derating information.
6. Current that causes a 40°C temperature rise from 25°C ambient. This
information is for reference only and does not represent absolute
maximum ratings.
Click for temperature derating information.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
