What are the key features of LQW18AN5N6D10D?
- Tight ±0.5 nH absolute inductance tolerance enables precise RF impedance matching in GHz-range circuits where percentage tolerances are insufficient for accurate network design
- Very low 0.045 Ω DC resistance with 900 mA current rating supports high-current RF choke and power-supply bypass applications with minimal resistive loss
- Wire-wound ferrite core construction in 1608/0603 SMD package achieves Q factor of 38, balancing RF efficiency and compact footprint for GHz-band circuit integration
What is LQW18AN5N6D10D used for?
The LQW18AN5N6D10D is designed for RF impedance matching networks, harmonic filters, and LC tank circuits in the 1 GHz to 6 GHz range, including 5G NR sub-6 GHz, Wi-Fi 5 GHz, and LTE band circuits. Its absolute ±0.5 nH tolerance makes it particularly valuable in antenna tuning and duplexer filter designs where precise inductance values are required to hit narrow pass-band frequency targets. The 900 mA current rating and low DC resistance also allow its use as an RF choke in power amplifier bias feeds within space-constrained RF front-end modules.

Frequently Asked Questions
Why is the ±0.5 nH absolute tolerance of LQW18AN5N6D10D important for 5G filter design?
At 0.0056 µH, a ±0.5 nH tolerance corresponds to approximately ±9% of the nominal value, but more importantly it defines a fixed absolute spread regardless of the design frequency. In 5G NR sub-6 GHz bandpass filters where each inductor must land within ±0.5 nH of the target to keep insertion loss below 1 dB and maintain band-edge selectivity, this tight absolute tolerance avoids filter tuning iterations that ±10% percentage-tolerance inductors would require.
What DC current and resistance specs make LQW18AN5N6D10D suitable for RF PA bias feeds?
The LQW18AN5N6D10D handles up to 900 mA DC current with a DC resistance of only 0.045 Ω, causing less than 41 mV voltage drop at full rated current. These parameters allow it to serve as an RF choke in power amplifier bias networks where the inductor must deliver substantial DC bias to the PA transistor while blocking RF signals from entering the supply rail, all with negligible power dissipation in the choke itself.
At what frequency range does the 0.0056 µH inductance of LQW18AN5N6D10D provide useful RF reactance?
The 0.0056 µH (5.6 nH) inductance presents a reactance of approximately 35 Ω at 1 GHz, 88 Ω at 2.5 GHz, and 175 Ω at 5 GHz. This makes LQW18AN5N6D10D most useful for impedance matching and choke functions in the 1 GHz to 6 GHz frequency range covering LTE, Wi-Fi 5 GHz, and 5G sub-6 GHz bands where moderate inductive reactance is required in a small SMD package.
How does the 1608/0603 package size of LQW18AN5N6D10D compare to smaller 0402 RF inductors when choosing for a compact RF module?
The 1608/0603 package (1.6 mm × 0.8 mm, 1.28 mm² board area) is slightly larger than an 0402 (1.0 mm × 0.5 mm, 0.5 mm² board area), but LQW18AN5N6D10D offers the advantage of a higher Q factor of 38 and tighter ±0.5 nH absolute tolerance, which smaller 0402 inductors at this inductance value may not match. For RF modules where filter performance is more critical than the marginal board space saving, the 0603 package is the better choice.
