Frequently Asked Questions
What inductance value and tolerance does the LQW18AN91NJ00D provide for RF filter design?
The LQW18AN91NJ00D provides 91 nH of inductance with a ±5% tolerance (J-grade), giving designers a predictable impedance at RF frequencies. This makes it suitable for narrow-band filters and impedance matching networks in the 100 MHz to 500 MHz range.
How much DC current can the LQW18AN91NJ00D handle before saturation becomes a concern?
The component is rated for a maximum DC current (Idc) of 230 mA. At this current level, designers should verify inductance roll-off, particularly for circuits simultaneously carrying DC bias and RF signals, such as RF power amplifier bias feeds operating from 3.3 V supplies.
Which wireless or RF application circuits benefit most from the LQW18AN91NJ00D's Q factor of 34?
A Q factor of 34 at the rated frequency makes this inductor well-suited for Bluetooth 2.4 GHz front-end matching, RFID reader circuits, and narrowband LC resonators. Higher Q reduces insertion loss in the passband, improving receiver sensitivity by several tenths of a dB.
What is the physical package size and how does it compare to 0402 inductors for board layout?
The LQW18AN91NJ00D uses the 1608 metric (0603 imperial) package, measuring 1.6 mm × 0.8 mm. This is roughly 2.5 times the pad area of a 0402 component, offering easier PCB placement tolerances while still maintaining a compact enough footprint for dense RF module designs.
