HALA0600503R High-Frequency Air Core Inductor (7nH ± 20%, 5-20GHz)

Product Overview

The HALA0600503R is an ultra-miniature, high-precision Air Core Inductor specifically engineered for high-frequency RF, microwave, and millimeter-wave applications. With a recommended operating frequency of 5GHz to 20GHz, this 7nH air coil offers an exceptionally high Self-Resonant Frequency (SRF) and a superior Q-factor, making it the ideal choice for modern wireless telecommunications and RF front-end modules.

Featuring a 6-turn helical structure utilizing 0.05mm ultra-fine copper wire with a 0.3mm inner diameter, the HALA0600503R ensures minimal parasitic capacitance and maximum stability in demanding environments ranging from -55℃ to +125℃.

Key Features & Advantages

1.Microwave & Millimeter-Wave Optimized: Designed to deliver outstanding performance across the 5-20GHz band.
2.Ultra-Fine Precision Engineering: Built with 0.05mm high-conductivity copper wire and a precise 0.3mm inner diameter for tight tolerance control (7nH ± 20%).

RF Assembly & Installation Guidelines (Crucial for Engineers)

To ensure maximum RF signal integrity and minimize parasitic inductance when assembling the HALA0600503R on your PCB:

•Perpendicular Alignment: During assembly, mount the main coil body perpendicular to the RF signal transmission line. This orientation significantly reduces electromagnetic coupling and crosstalk.
•Minimize Lead Length: Keep the leads connecting the inductor to the transmission line trace as short as possible to prevent unwanted lead inductance from shifting the circuit's operating frequency.
•Mechanical Securing: After manual tuning and calibration, it is highly recommended to apply a small drop of low-dielectric RF glue/epoxy to secure the coil body to prevent detuning from physical vibration.

Typical Applications

Due to its ultra-high frequency response, the HALA0600503R is widely adopted by global Tier-1 hardware manufacturers in:

•5G Millimeter-Wave (mmWave) Communication Base Stations
•RF Front-End Modules (FEM) & Power Amplifiers (PA)
•Optical Transceivers (SFP+/QSFP modules)
•Satellite Communication (Satcom) Systems
•Professional & Aerospace Radar Systems
•High-Speed Broadband Test and Measurement Equipment
