1. Please specify

termination

and

packaging

codes:

MSS1278-105KLD

Termination:L

=RoHS compliant matte tin over

nickel over phos bronze.

Special order:

= RoHS tin-silver-copper

(95.5/4/0.5) or

= non-RoHS

tin-lead (63/37).

Packaging: D

=13″ machine-ready reel. EIA-

481 embossed plastic tape

(500 parts per full reel).

=Less than full reel. In tape, but

not machine 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 us-

ing 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 4191A or

equivalent.

5. DC current at which the inductance drops the

specified amount 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.
