Notes

When ordering, please specify lead length and termination codes: e.g. RFC0810B-183KE
Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc; measured on an Agilent/HP 4284A LCR meter or equivalent.
DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 4191A or equivalent. Details
Isat: DC current at 25°C that causes the specified 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.

Lead Length:

A = 3.6 mm ±0.3 mm (special order)
B = 5.0 mm ±0.5 mm
C = 7.0 mm ±0.5 mm (special order)
D = 8.0 mm ±0.5 mm (special order)
E = 10.0 mm ±1.0 mm (special order)
F = 25.0 mm ±1.0 mm, packaged in fanfold tape, 800 parts per box (special order)

Termination:

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

Environmental

General specification

Core Material:

Ferrite

Weight:

2.0 – 2.3 g

Packaging:

150 parts per tray (all except 25 mm lead length). In fanfold tape, 800 parts per box (25 mm lead length only).

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.
