1. Please specify termination and packaging codes:
MSS1038-105KLC
Termination: L = RoHS compliant matte tin over nickel
over copper.
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 (250 parts
per full reel). Quantities less than full
reel available: in tape (not machineready) or with leader and trailer ($25charge).
B = Less than full reel. In an effort tosimplify our part numbering system,
Coilcraft is eliminating the need formultiple packaging codes. Whenordering, simply change the last letter of your part number from B to C.
D = 13″ machine-ready reel. EIA-481
embossed plastic tape. Factoryorder only, not stocked (1000 parts
per full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc
using an Agilent/HP 4263B LCR meter or equivalent.
3. SRF measured using an Agilent/HP 8753D or equivalent.
5. DC current at 25°C that causes the specified inductance drop from its value without current.
Click for temperature derating information.
5. Current that causes the specified temperature rise from25°C ambient. This information is for reference onlyand does not represent absolute maximum ratings.
Click for temperature derating information.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”
before soldering.
