HALA0800503R Air Core Inductor: 11nH, 8-Turn RF Coil (4–20 GHz)
Why Choose the HALA0800503R for High-Frequency RF Applications?
In high-frequency RF front-ends, power amplifiers, and millimeter-wave (mmWave) systems, standard SMD chip inductors often fail due to core losses and low Self-Resonant Frequency (SRF). The HALA0800503R Air Core Inductor resolves this bottleneck.
By utilizing an air-core (hollow-core) design, this micro-spring coil eliminates magnetic saturation and core-induced distortions. Wound with precisely 8 turns of 0.05mm high-conductivity enameled wire, it delivers a stable 11 nH ± 20% inductance with an ultra-high Q-factor across the 4 GHz to 20 GHz frequency band.

Engineering Mounting & PCB Layout Best Practices
To ensure the HALA0800503R operates at its peak performance without introducing unwanted parasitic capacitance, RF design engineers must follow these guidelines:
•Avoid Solder Bridging at the Base: The leads are tinned to the root. Ensure precision soldering to avoid solder run-up onto the active turns.
•Perpendicular PCB Placement: Always mount the helical coil axis perpendicular to the RF signal microstrip/stripline. This drastically minimizes unwanted electromagnetic coupling.
•Keep Leads Ultra-Short: Although the lead length is ≥8.0mm,prune them to the minimum necessary length on the PCB to prevent parasitic lead inductance.
•Post-Tuning Immobilization: Once the RF circuit tuning is finalized, apply a drop of low-loss, low-dielectric RF glue to secure the 8-turn body against physical shock.

FAQ
Q1: Can I request customized turns or lead lengths for the HALA0800503R?
A: Yes. We provide flexible custom winding services. While the standard HALA0800503R has 8 turns with leads ≥ 8.0mm, we can adjust the turn count, wire diameter, and pitch to meet your specific RF matching needs.
Q2: What is the shelf life and storage recommendation for these micro air coils?
A: Because the leads are tinned to the root, they must be stored at 20–25℃ and 40%–60% RH to prevent tarnish or oxidation. Under these conditions, the shelf life is 1 year.
Q3: What is the lead time for batch B2B orders?
A: We keep standard stock of HALA0800503R for rapid prototyping. For bulk wholesale orders, lead times typically range from 1 to 2 weeks depending on the quantity.
