Frequently Asked Questions
What inductance and Q factor does LQW18AN68NJ00D provide for RF circuit design?
The LQW18AN68NJ00D offers 68 nH nominal inductance with ±5% tolerance and a Q factor of 38. A high Q value reduces resistive losses in RF filter and matching networks, which is critical for maintaining signal integrity in designs operating above 100 MHz, such as Bluetooth or Zigbee antenna matching stages.
Can LQW18AN68NJ00D handle the current demands of a DC bias choke in a low-power RF module?
Yes, the component is rated for 340 mA DC current with a DC resistance of 0.38 Ω. At 340 mA, resistive power dissipation is approximately 49 mW, which is within safe limits for low-power RF module bias chokes. For current paths below 200 mA, the temperature rise remains well under 20 °C in typical PCB conditions.
How does the 0603 package of LQW18AN68NJ00D compare to larger 0805 inductors for high-density layouts?
The 0603 package (1608 metric, approximately 1.6 mm × 0.8 mm) occupies about 40% less PCB area than a standard 0805 component. This allows RF filter ladders with multiple inductors to fit within the tight footprint constraints of wearable devices and multi-band modules, where every square millimeter of board space is premium and component count per area can exceed 50 parts per cm².
What manufacturing lead time should engineers plan for when sourcing LQW18AN68NJ00D in production volumes?
Murata lists a factory lead time of 14 weeks for LQW18AN68NJ00D. Production planners should include this 14-week buffer in BOM freeze schedules and consider safety-stock levels of 4 to 8 weeks of consumption to avoid line stoppages. Authorized distributors often carry buffer stock that can reduce effective lead time for quantities up to a few thousand pieces.
