Key Features
- High Q factor of 40 at RF frequencies combined with only 0.05 Ω DC resistance minimizes insertion loss in low-impedance RF filtering and matching networks
- 1000 mA rated DC current capacity enables use in power management and high-current RF signal paths without saturation
- Wire-wound ferrite core construction in 2015/0805 SMD package provides stable 0.0188 µH inductance for high-frequency circuit designs
Applications
The LQW2BHN18NK13L is designed for low-impedance RF choke and impedance matching applications in wireless communication modules, cellular front-end circuits, and high-frequency power management designs. Its combination of high Q factor (40) and high current rating (1000 mA) makes it effective in noise suppression filters for power rails adjacent to sensitive RF circuitry. The 0805 SMD package suits automated assembly in compact RF modules for 5G, LTE, and Wi-Fi applications.

Frequently Asked Questions
What current can LQW2BHN18NK13L handle and how does that benefit RF power amplifier bias circuits?
The LQW2BHN18NK13L supports up to 1000 mA DC current with a very low 0.05 Ω DC resistance, making it ideal as an RF choke in power amplifier bias feeds where the inductor must pass large DC bias currents without significant voltage drop while blocking RF signals from the DC supply rail. This combination reduces bias network power loss and improves PA efficiency.
For which frequency ranges is the LQW2BHN18NK13L with 0.0188 µH inductance most effective as an RF choke?
At 0.0188 µH, the LQW2BHN18NK13L presents useful reactance starting above approximately 100 MHz, making it most effective as an RF choke in the 500 MHz to 6 GHz range covering cellular LTE, 5G sub-6 GHz, and Wi-Fi 2.4 GHz and 5 GHz bands. Its Q factor of 40 ensures low loss at these frequencies, maintaining signal integrity in RF front-end designs.
How does the ±10% inductance tolerance of LQW2BHN18NK13L impact impedance matching network design?
The ±10% tolerance on 0.0188 µH means the actual inductance may range from 0.0169 µH to 0.0207 µH. In narrow-band impedance matching networks targeting a specific frequency, this variation can shift the matched impedance by several ohms, so designers should simulate across the tolerance range or choose a tighter-tolerance variant if the application requires precise 50 Ω system matching within ±1 dB.
When should a designer choose the 2015/0805 package of LQW2BHN18NK13L instead of an 0402 RF inductor?
The 2015/0805 (2.0 mm × 1.5 mm) package of LQW2BHN18NK13L is preferred over 0402 inductors when the circuit requires 1000 mA current handling or when the higher Q factor of 40 is needed to achieve low insertion loss. The larger footprint at 3.0 mm² also improves thermal performance and mechanical solder joint reliability in applications subject to vibration or high-current thermal cycling.
