Surface Mount Transformers/Inductors,

Gapped and Ungapped Custom Configurations Available

NOTE: Pad layout guidelines per MIL-STD-275E

(printed wiring for electronic equipment).

Tolerances: xx ± 0.01" [± 0.25 mm]; xxx ± 0.005"

[± 0.12 mm]

The underside of these components contains

metal and thus should not come in contact with

active circuit traces.

ELECTRICAL SPECIFICATIONS

Inductance Range: 10 µH to 47 000 µH, measured at 0.10 V RMS at

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

impedance analyzer

DC Resistance Range: 0.03

Ω to 19.1 Ω, measured at + 25 °C ± 5 °C

Rated Current Range: 2.00 amps to 0.09 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.
