1. When ordering, please specify termination code:
MSS1812T-105KED
4. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
5. DC current at 25°C that causes the specified inductance drop from its
value without current.
Click for temperature derating information..
Termination: E = RoHS compliant matte tin over nickel over phos bronze.
Special order:
6. Current that causes the specified temperature rise from 25°C ambient.This
information is for reference 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 Mount Components” before soldering.
Q = RoHS tin-silver-copper (95.5/4/0.5) or
P = non-RoHS tin-lead (63/37).
Packaging: D = 13″ machine-ready reel. EIA-481 embossed
plastic tape. Factory order only, not stocked
(175 parts per full reel). Quantities less than full
reel available: in tape (not machine 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 a Coilcraft CCF858 test fixture.
