Notes

When ordering, please specify termination code: e.g. DO3340H-105KLD
Inductance tested at 10 kHz, 0.1 Vrms, 0 A using an Agilent/HP 4263B LCR meter or equivalent.
SRF measured using Agilent/HP 8753D network analyzer.
Isat: DC current at which inductance drops 30% (typ) from its value without current. For other operating temperatures, use this DCR at Temperature calculator.
Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Termination:

L = RoHS compliant tin-silver-copper over copper.
S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (350 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).

Environmental

Environmental:

RoHS compliant

Ambient temperature range:

−40°C to +85°C with Irms current

Storage temperature range:

Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C

Maximum part temperature:

+125°C (Ambient + temperature rise)

General specification

Core Material:

Ferrite

Weight:

1.907 – 2.856 g

Packaging:

350 per 13″ reel; Plastic tape: 24 mm wide, 0.5 mm thick, 16 mm pocket spacing, 11.7 mm pocket depth

Soldering/Washing

Moisture Sensitivity Level (MSL):

1 (unlimited floor life at <30°C / 85% relative humidity)

Resistance to soldering heat:

Max three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.

Refer to Soldering Coilcraft Components before soldering.

PCB Washing:

Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
