1. When ordering, specify tolerance, termination and packaging codes:
MSS7341-872NLD
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft
SMD-A fixture in an Agilent/HP 4263B LCR meter.
3. Tolerances in bold are stocked for immediate shipment.
Tolerance:
M= 20%, N = 30% (Table shows stock tolerances in bold.)
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.
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.
Termination: L = RoHS compliant matte tin over nickel over phos bronze
Special order:T = RoHS tin-silver-copper
(95.5/4/0.5) over gold over nickel over phos bronze
or S = non-RoHS tin-lead (63/37) over gold over
nickel over phos bronze.
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (1200 parts per full reel).
7. Electrical specifications at 25°C.
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge),
use code letter D instead.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
