  • Wirewound construction provides higher Q than multilayer inductors
  • 0603 compact footprint for high-density RF layouts

The LQW18AN62NG00D from Murata is a 62nH ±2% wirewound RF inductor in an 0603 (1608 metric) package, part of the LQW18AN_00 series. The Murata part numbering: LQW=LQW series (wirewound RF inductor), 18=size code (0603), A=wirewound type, N=tolerance (±2%), 62=inductance code (62nH), N=±2% again, G00=individual code, D=packaging (180mm paper taping, 4000pcs/reel). The wirewound construction provides significantly higher Q factor than multilayer inductors at the same inductance value, making it the preferred choice for loss-sensitive RF circuits. The ±2% tolerance ensures precise impedance matching in RF front-end modules. The 2.3GHz minimum SRF allows reliable operation up to approximately 1.5GHz (typically using inductors at less than 1/3 to 1/2 of SRF). The 280mA rated current and 0.51Ω DCR are suitable for RF signal paths with moderate current levels.

The LQW18AN62NG00D uses a wirewound construction where a fine insulated copper wire is wound around a ferrite core in a precision winding pattern. The ferrite core increases the inductance per unit volume compared to an air-core design, enabling 62nH in a compact 0603 package. The wirewound construction provides much higher Q factor than multilayer (thick-film) inductors because: (1) the wound wire has lower resistance than the thick-film electrode, (2) the ferrite core concentrates the magnetic flux, and (3) the wire spacing can be optimized for low parasitic capacitance. The self-resonant frequency (SRF) of 2.3GHz is determined by the parallel resonance of the inductance and the parasitic capacitance between windings. Above the SRF, the component behaves as a capacitor. The ±2% tolerance is achieved through precision winding equipment and laser trimming of the wire length.

  • 2.4GHz Bluetooth PA output 62nH matching inductor in L-network for 50Ω impedance
  • GPS L1 (1575MHz) LNA input 62nH matching inductor with Q=38 for low noise figure
  • UHF (400-500MHz) VCO tank inductor 62nH for stable oscillation frequency
  • Cellular (700-900MHz) RF front-end 62nH matching inductor for antenna switch module
  • Wi-Fi 2.4GHz LNA output 62nH inductor in Pi-network for impedance transformation
