1. Please specify tolerance, termination and packaging codes:
DO3308P-105MLD
Tolerance: M= 20%  K = 10%
Termination: L = RoHS compliant gold over nickel over
phos bronze.
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 em-
bossed plastic tape (1000 parts per full
reel).
B = Less than full reel. In tape, but not ma-
chine 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. DC current at which 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.
