LQH32NH3R3J23L Typical application Circuitry

The LQH32NH3R3J23L is a fixed inductor component manufactured by Murata, primarily utilized in electronic circuits for its energy storage, signal filtering, and impedance matching capabilities. It's particularly relevant in applications such as power supply circuits, noise suppression in signal lines, and stabilizing the operations of sensitive electronic components.

LQH32NH3R3J23L Characteristics:

- Inductance: The LQH32NH3R3J23L provides an inductance of 3.3µH, suitable for circuits that require a moderate level of inductance.

- Current Capacity: It can manage a maximum current of 720mA.

- Resistance: The inductor has a DC resistance of 0.11Ω, which impacts the circuit's efficiency by causing power loss as heat.

- Form Factor: With a 1210 (3225 Metric) size, the LQH32NH3R3J23L is designed for surface-mount technology, making it a practical choice for compact PCB layouts.

Utilization in a Buck Converter Circuit:

The LQH32NH3R3J23L is often employed in buck converter circuits, which are used to step down voltage efficiently from a higher level to a lower level.

Circuit Connection Overview:

1. Integrating LQH32NH3R3J23L: In the buck converter, the LQH32NH3R3J23L is typically placed in series with the output. Connect the source voltage to the first terminal of the LQH32NH3R3J23L (pin 1), and connect its second terminal (pin 2) to the drain of the switching MOSFET.

2. MOSFET Configuration: A MOSFET serves as the switch in the circuit. The source of the MOSFET is connected to the ground, and its gate is connected to a PWM control signal.

3. Output Capacitor and Load: An output capacitor is connected in parallel with the load to the second terminal of the LQH32NH3R3J23L. This capacitor helps in smoothing out the output voltage.

4. Feedback Loop for Voltage Control: Implement a feedback mechanism, often involving a voltage divider connected to the output, feeding into a control circuit to ensure that the output voltage remains stable despite variations in the input voltage or load.

Design Considerations:

- Current Handling: Ensure that the current through the LQH32NH3R3J23L does not exceed 720mA to prevent inductor saturation and potential damage.

- Heat Dissipation Management: Given its 0.11Ω resistance, the LQH32NH3R3J23L will generate heat. Adequate thermal management strategies are crucial, particularly in compact designs or high-power applications.

- Frequency Consideration: The LQH32NH3R3J23L operates efficiently at specific frequencies. The switching frequency of the buck converter should be chosen by considering the inductor's characteristics to maximize efficiency.

- PCB Layout Planning: Although the LQH32NH3R3J23L is compact, ensure sufficient space is provided around it on the PCB to prevent interference with other components and to comply with the recommended footprint for optimal performance.

In conclusion, the LQH32NH3R3J23L is integral to various electronic circuits, especially in power conversion applications like buck converters where precise voltage regulation and efficient power handling are essential. The design and deployment of circuits incorporating the LQH32NH3R3J23L necessitate a comprehensive understanding of the circuit's requirements, considering factors such as power handling, thermal management, and the spatial arrangement of components.
