CHARACTERISTICS
INDUCTANCE RANGE .10 µH to 470 µH. Values under .10 µH
are available by special order.
TOLERANCE 20% from .10 µH to .82 µH. 10% from 1.0 µH to
1000 °H. Also available in 5% tolerance for values from 10
µH to 470 µH.
CURRENT RATING Based on current flow and temperature
rise of 20°C maximum at 80°C ambient temperature.
TESTING PROCEDURE Inductance, Q and SRF are mea-
sured with HP4191A Impedance Analyzer with 16092A Test
Clip at specified frequency. DCR measured with digital
milliohms meter.
DIELECTRIC STRENGTH 500 volts RMS at sea level.
OPERATING TEMPERATURE -25°C to +85°C.
STORAGE TEMPERATURE 45°C to 100°C in original tape and
reel package.
SOLDERING HEAT RESISTANCE 250°C for 3-5 seconds after
120°C preheat cycle for 5 minutes.
SOLDERABILITY 95% of the terminal is covered with solder.
RESISTANCE TO SOLVENT No change in appearance when
dipped into alcohol or freon for 3 minutes.
MARKING Part is marked with inductance value in EIA
code.
PACKAGING Tape and Reel only.
