ELECTRICAL SPECIFICATIONS

(Multiple winds are connected in parallel)

Inductance Range: 10 µH to 150 000 µH, measured at 0.10 V RMS

at 10 kHz without DC current, using an HP 4263 or HP 4284A

impedance analyzer

DC Resistance Range: 0.02

Ω to 46.2 Ω, measured at + 25 °C ± 5 °C

Rated Current Range: 3.20 amps to 0.17 amps

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

* 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 %.

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.
