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.

• Handle saturating currents up to 4.2 Amps

• Defense Supply Center CID: A-A-59738

Designer’s Kit C309 contains 3 each of all values

Core material Ferrite
