1. Please specify tolerance, termination and packaging codes:
DO3308P-105MLD

Tolerance: M = 20% K = 10%Termination: L = RoHS compliant gold over nickel overphos 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
embossed plastic tape (1000 parts per
full reel). Quantities less than full reelavailable: in tape (not machine ready) orwith leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify
our part numbering system, Coilcraft
is eliminating the need for multiple
packaging codes. When ordering, simply
change the last letter of your part number from B to D.
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.
