1. Please specify termination and packaging codes:
MSS1260-184KLD
Termination: L =RoHS compliant matte tin over
nickel over phos bronze.
Special order:
T = RoHStin-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
(500 parts per full reel).
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.
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc
using 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 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.
