1. Please specify

termination and packaging codes:

MSS1246-105KLC

Termination:L =RoHS compliant matte tin 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: C=7

″ machine-ready reel. EIA-481

embossed plastic tape (200 parts

per full reel).

B=Less than full reel. In tape, but

not machine ready. To have a

leader and trailer added ($25

charge), use code letter C

instead.

D=13

″ machine-ready reel. EIA-481

embossed plastic tape. Fac-

tory order only, not stocked

(800 parts per full reel).

2. Inductance measured at 100 kHz, 0.1 Vrms,

0 Adc using a Coilcraft SMD-A fixture in an

Agilent/HP 4263B LCR meter or equivalent.

3. DCR measured on a micro-ohmmeter and a

Coilcraft CCF858 test fixture.

4. SRF measured using an Agilent/HP 8753D

network analyzer and a Coilcraft SMD-D test

fixture.

5. DC current at which the inductance drops 10%

(max) from its value without current.

6. Current that causes the specified temperature rise

from 25°C ambient.

7. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount

Components” before soldering.

• 12 × 12 mm footprint; 4.6 mm high shielded inductors

• Very low DCR and excellent current handling
