ZA9423 Series

High Current Air Core Inductors

The ZA9423-33N and the ZA9423-66N high-frequency, high-current, surface-mount inductors are perfectly suited for use as low-loss chokes in RF amplifiers for HF, VHF, ISM, broadcast, and aerospace applications. Their high Q factors and high current ratings give designers great options for powerful RF amplifier designs.

Significantly high Q factor – twice as high as 2014VS
High current handling
Ideal for use as a low-loss choke on RF power amplifiers

Notes

Inductance measured at 1.0 MHz, 0.1 Vrms, 0 A using an Agilent/HP HP4291A impedance analyzer with an Agilent/HP 16193A test fixture or equivalent.
Q measured at the specified frequency using an Agilent/HP 4291A impedance analyzer or equivalent.
SRF measured using an Agilent/HP 8753 network analyzer or equivalent and a Coilcraft CCF1199 test fixture.
DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
