1. When ordering, please specify termination and packaging codes:
DO1605T-105MLC
Termination: L = RoHS compliant silver-palladium-platinum-glass frit
Special order: T = RoHS tin-silver-copper
(95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
Packaging: C = 7machine-ready reel. EIA-481 embossed plastic
tape (1000 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.
D = 13machine-ready reel. EIA-481 embossed plastic
tape (3500 parts per full reel).
2. Inductance tested at 100 kHz, 0.1 Vrms.
3. SRF >13 MHz measured using Agilent/HP 8753D network analyzer;
<13 MHz using Agilent/HP 4192A.
4. DC current at which the inductance drops 10% (typ) from its value
without current.
5. Current that causes a 40°C temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
