1. When ordering, specify
tolerance, termination
and
packaging
codes:
DO3316T-474MLD
Tolerance: M =
20%,
K
= 10% (Table shows stock tolerances in bold.)
Termination: L
= RoHS compliant tin-silver-copper over copper.
Special order:
S
= non-RoHS tin-lead (63/37).
Packaging: D
= 13″ machine-ready reel. EIA-481 embossed plastic
tape (750 parts per full reel).
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 tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. Tolerances in bold are stocked for immediate shipment.
4. SRF measured using Agilent/HP 8753D network analyzer.
5. DC current at 25°C that causes an inductance drop of 10% (typ) 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 maxi-
mum ratings.
Click for temperature derating information.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
