The 1010 High Current Air Coil is a high-performance High Current Air Core Inductor engineered by Infinity Electronics, designed for high-frequency, high-current electronic applications where magnetic stability and low power loss are critical. As a coreless inductive component, this 1010 Series RF Air Coil eliminates magnetic saturation and core loss issues that plague traditional cored inductors, delivering reliable performance across extreme operating conditions. With an inductance range of 22 nH to 146 nH, ultra-low DC resistance (RDC), and an extremely high Q-factor, it is optimized for high-speed electronic systems with clock frequencies exceeding 4 MHz. The 1010 High Frequency High Current Air Coil operates stably from -40 °C to +125 °C, making it a staple component for industrial, automotive, and RF power electronics. Its compact design and high current handling capability further solidify its position as a top choice for ToB customers in power conversion and signal processing industries.
As an air-core inductor, the 1010 High Current Air Coil has no magnetic core material, eliminating saturation even under maximum rated current and ensuring consistent inductance performance over time. This coreless design also results in zero core losses, significantly improving energy efficiency in high-current circuits.
Boasting a minimum Q-factor of 163–223 at 100 MHz and ultra-low maximum RDC (1.2 mΩ–3.33 mΩ), this air coil minimizes signal attenuation and power dissipation, ideal for high-frequency RF and power conversion applications that demand low loss and high signal integrity.
With an operating temperature range of -40 °C to +125 °C, it adapts to harsh industrial and automotive environments. The 1010 High Current Air Coil supports rated currents from 19 A to 30 A, meeting the high-current demands of DC-DC converters and RF power amplifiers.
Featuring a resonant frequency (fres) of 332 MHz to 867 MHz, it maintains stable performance in high-frequency circuits above 4 MHz, outperforming standard inductors in high-speed electronic systems.
