1. When ordering, specify tolerance, termination and packaging codes:
DO3316H-472MLD
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 C instead.
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP
4263B LCR meter or equivalent.
3. Tolerances in bold are stocked for immediate shipment.
4. SRF measured using Agilent/HP 8753D network analyzer.
5. DC current at which the inductance drops 10% (typ) from its value without current.
6. Current that causes a 40°C temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
