Notes

When ordering, please specify termination and packaging codes: e.g. DO1608C-105MLC
Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent.
Tolerances in bold are stocked for immediate shipment
DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
Isat: DC current at 25°C that causes a 10% (typ.) inductance drop from its value without current.
Temperature derating curves.
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. Temperature derating curves.

Tolerance:

K = 10%, M = 20% (Table shows stock tolerances in bold.)

Termination:

L = Gold over nickel over moly-manganese terminations.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

C = 7" machine-ready reel
EIA-481 embossed plastic tape (750 per full reel).
B = Less than full reel
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 C.
D = 13" reel, machine-ready
EIA-481 embossed plastic tape. Factory order only, not stocked (2500 per full reel).

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:

128– 164 mg

Packaging:

750/7″ reel; 2500/13″ reel Plastic tape: 12 mm wide, 0.28 mm thick, 4 mm pocket spacing, 3 mm pocket depth

Soldering/Washing

Moisture Sensitivity Level (MSL):

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

Resistance to soldering heat:

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.
