1. Please specify termination and packaging codes:
MSS1246H-105KED
Termination: E =RoHS compliant matte tin overnickel over phos bronze.
Special order:
T = RoHS tin-silver-copper(95.5/4/0.5) or S = non-RoHS
tin-lead (63/37).
Packaging: D =13″ machine-ready reel. EIA-481
embossed plastic tape (800 parts
per full reel). Quantities less thanfull reel available: in tape (notmachine ready) or with leader
and trailer ($25 charge).
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 aCoilcraft CCF858 test fixture.
4. SRF measured using an Agilent/HP 8753D
network analyzer and a Coilcraft SMD­‑D testfixture.
5. DC current at 25°C that causes the specified
inductance drop from its value without current.
Click for temperature derating information.
6. Current that causes the specified temperaturerise from 25°C ambient. This information is forreference only and does not represent absolute
maximum ratings.
Click for temperature derating information.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface MountComponents” before soldering.
