ELECTRICAL SPECIFICATIONS

Inductance Range: 10

µH to 47000µH, measured at 0.10V RMS @ 10kHz without

DC current, using an HP 4263A or HP 4284A impedance analyzer.

DC Resistance Range: 0.03 ohm to 19.1 ohms, measured at + 25

°C ± 5°C.

Rated Current Range: 2.00 amps to .09 amps.

Dielectric Withstanding Voltage: 500V RMS, 60Hz, 5 seconds.

Surface Mount Transformers/Inductors,

Gapped and Ungapped, Custom Configurations Available

UNGAPPED MODELS: Highest possible inductance with the lowest DCR and highest Q

capability. Beneficial in filter, impedance matching and line coupling devices.

GAPPED MODELS: Capable of handling large amounts of DC current, tighter inductance

tolerance with better temperature stability than ungapped models. Beneficial in DC to DC

converters or other circuits carrying DC currents or requiring inductance stability over a

temperature range.

*DC current that will create a maximum temperature rise of 30

°C when applied at + 25°C

ambient. **DC current that will typically reduce the initial inductance by 20%.
