What are the key features of LQH32PN330MN0L?
- 33 µH inductance at ±20% tolerance for versatile power filtering and energy storage in switching regulators
- Magnetically shielded ferrite core construction minimizing EMI radiation and coupling to adjacent PCB components
- 1.38 Ω DC resistance enabling efficient power handling with controlled I²R losses in converter output stages
- Compact 1210 (3225) SMD package allowing high-density PCB placement in space-constrained power modules
What is LQH32PN330MN0L used for?
LQH32PN330MN0L is used as an output filter inductor in DC-DC buck and boost converters where 33 µH inductance reduces output current ripple at switching frequencies from 50 kHz to 300 kHz. Its magnetically shielded ferrite construction makes it well-suited for EMI-sensitive applications such as RF module power supplies and analog signal chain circuits where inductor flux leakage would increase noise floor. The 1210 package footprint and general-purpose rating also make it suitable for bulk choke filtering on low-current rails in industrial sensor boards and consumer electronics power stages.

Frequently Asked Questions
What inductance value and DC resistance does LQH32PN330MN0L provide, and how do these parameters affect converter efficiency?
LQH32PN330MN0L offers 33 µH nominal inductance with a DC resistance (DCR) of 1.38 Ω. At a continuous output current of 100 mA, the I²R loss in the inductor is approximately 13.8 mW, which is acceptable for low-current converters but limits efficiency at higher currents. For applications requiring currents above 200 mA, selecting a lower-DCR inductor in the same 1210 package with DCR below 0.5 Ω would reduce copper losses and improve overall converter efficiency by 1% to 3%.
Why does the magnetically shielded construction of LQH32PN330MN0L benefit RF and analog circuit designs?
The magnetically shielded ferrite core in LQH32PN330MN0L confines the inductor's magnetic flux within the core structure, reducing stray field radiation to less than 10% of the level produced by an unshielded wirewound inductor of similar inductance. This shielding is critical in RF module power supplies and audio circuit power rails where stray magnetic fields from an unshielded 33 µH choke operating at 100 kHz could couple into adjacent low-noise amplifier inputs and raise the system noise floor by several µV.
At what switching frequency range is a 33 µH inductor like LQH32PN330MN0L most effective in a buck converter?
A 33 µH inductor is most effective in buck converters operating at switching frequencies between 50 kHz and 300 kHz, where the inductance provides sufficient energy storage to maintain continuous conduction mode (CCM) at output currents above approximately 50 mA with a 5 V input and 3.3 V output. At frequencies above 500 kHz, the 1.38 Ω DCR and core losses of the LQH32PN330MN0L's ferrite material make smaller 4.7 µH to 10 µH inductors a more efficient choice, as the higher switching frequency reduces the required inductance for the same ripple current specification.
How does LQH32PN330MN0L's 1210 package compare to a 0805 inductor of similar inductance for power supply layout?
The 1210 (3225) package of LQH32PN330MN0L is 3.2 mm × 2.5 mm versus the 2.0 mm × 1.25 mm footprint of an 0805 inductor, providing approximately 60% more surface area for heat dissipation and allowing a larger core volume that supports the 33 µH inductance value at acceptable saturation current levels. A 33 µH 0805 inductor would typically have 40% lower saturation current and higher DCR above 2.5 Ω compared to LQH32PN330MN0L, making the 1210 package the practical minimum for 33 µH at DC currents above 80 mA.
