Key Features
- 43 nH inductance with only 0.29 Ω DC resistance in a compact 0603 (1608) package minimizes resistive losses in RF signal paths
- Wirewound chip construction on 1608 case size delivers stable inductance characteristics at RF frequencies for reliable filter and matching network performance
- RoHS-compliant lead-free construction (Pb-free) ensures compatibility with modern green manufacturing and wave or reflow solder processes
Applications
LQW18AN43NJ00D is optimally suited for RF impedance matching networks, bandpass filters, and LC tank circuits in wireless communication modules operating at frequencies from tens of MHz to several GHz. Its 43 nH inductance and low 0.29 Ω DC resistance make it an effective component in Bluetooth, Wi-Fi, and sub-GHz IoT front-end designs where efficient signal coupling and minimal insertion loss are critical. The compact 0603 footprint also fits noise suppression choke applications on high-speed PCB power rails in mobile and wearable devices.

Frequently Asked Questions
What inductance value and DC resistance does LQW18AN43NJ00D offer, and how does this affect RF circuit efficiency?
LQW18AN43NJ00D provides a nominal inductance of 43 nH with a DC resistance of 0.29 Ω in a 0603 (1608 metric) package. The low DCR minimizes resistive power loss in RF signal paths, making this inductor efficient for impedance matching and LC filter circuits operating at frequencies from 100 MHz to several GHz in wireless communication designs.
In which RF wireless bands is LQW18AN43NJ00D most suitable as a matching or filtering inductor?
With 43 nH inductance and wirewound chip construction, LQW18AN43NJ00D is well matched for RF circuits in the 433 MHz, 868 MHz, and 915 MHz sub-GHz ISM bands, as well as 2.4 GHz Bluetooth and Wi-Fi front-end matching networks. At these frequencies, 43 nH provides practical impedance values of 120 Ω to 670 Ω that suit antenna matching and bandpass filter designs.
How does the 0603 package size of LQW18AN43NJ00D benefit PCB layout in compact IoT and wearable device designs?
The 1608 (0603 imperial) case size of LQW18AN43NJ00D measures only 1.6 mm x 0.8 mm, allowing it to fit within tight PCB footprints on IoT modules and wearable devices where board area is limited to a few square centimeters. This compact footprint also enables close component placement to minimize parasitic inductance in RF matching network layouts.
Is LQW18AN43NJ00D a drop-in alternative to other 43 nH inductors in the LQW18 series, and what distinguishes the AN variant?
Yes, within the Murata LQW18 series, LQW18AN43NJ00D shares the same 0603 footprint and 43 nH nominal inductance with other LQW18 variants, making footprint-compatible substitution straightforward. The AN designation specifies a wirewound air-core construction with a ±5% inductance tolerance (J code), distinguishing it from tighter-tolerance variants and ensuring consistent RF performance across production lots.
