What are the key features of LQM21NNR22K10D?

0.22 µH nominal inductance with ±10% tolerance in a compact 0805 (2012 metric) SMT package for space-efficient placement
Magnetically shielded ferrite core construction reduces EMI coupling to adjacent components on dense PCBs
Low 0.38 ohm DC resistance minimizes power dissipation in RF filtering and DC-DC converter input/output circuits
Suitable for RF and general-purpose applications including noise suppression, power decoupling, and impedance matching

What is LQM21NNR22K10D used for?

The LQM21NNR22K10D is well suited for RF noise filtering, impedance matching networks, and power line decoupling in wireless communication modules, Bluetooth, Wi-Fi, and IoT nodes requiring a compact 0.22 µH inductor. Its magnetically shielded design prevents flux leakage from disturbing neighboring components in high-density 0805 SMT layouts. This inductor is also used in DC-DC converter input/output filtering and general-purpose RF circuit designs where stable inductance and low DC resistance are required.

Frequently Asked Questions

What inductance value and tolerance does the LQM21NNR22K10D offer in its 0805 SMT package?

The LQM21NNR22K10D delivers 0.22 µH nominal inductance at ±10% tolerance with a DC resistance of 0.38 ohm in a compact 0805 SMT footprint, making it suitable for RF noise filtering, power decoupling, and general-purpose inductor applications in wireless communication and IoT circuit designs.

Which wireless and RF module designs benefit most from the magnetically shielded construction of the LQM21NNR22K10D?

Wi-Fi, Bluetooth, and Zigbee module designs operating above 100 MHz benefit most from the magnetically shielded ferrite core, which contains flux and prevents the 0.22 µH inductor from coupling interference into adjacent sensitive RF traces and analog circuits in compact multi-layer PCB assemblies.

How does the LQM21NNR22K10D compare to unshielded 0805 inductors for DC-DC converter noise suppression?

The shielded ferrite core in the LQM21NNR22K10D confines magnetic flux and reduces radiated EMI compared to unshielded wire-wound 0805 inductors, while its 0.22 µH value and 0.38 ohm DC resistance effectively suppress switching noise on 5 V DC-DC converter output rails without contributing excessive conduction losses.
