LQH32CN4R7M33L Typical application Circuitry

The LQH32CN4R7M33L is a fixed inductor component manufactured by Murata, widely recognized for its application in electronic circuits where energy storage, signal smoothing, and impedance matching are crucial. It's especially prevalent in applications such as power supply circuits, noise suppression in signal lines, and in RF communication systems for its reliability and performance.

LQH32CN4R7M33L Parameters:

- Inductance: The LQH32CN4R7M33L has an inductance of 4.7µH, which is optimal for applications that require a lower level of inductance.

- Current Capacity: It is designed to handle a maximum current of 680mA.

- Resistance: The inductor exhibits a DC resistance of 0.12Ω, which can result in power dissipation as heat within the circuit.

- Form Factor: With a 1210 (3225 Metric) size, the LQH32CN4R7M33L is structured for surface-mount technology, making it a practical choice for compact PCB layouts.

Application in a Buck Converter Circuit:

The LQH32CN4R7M33L is commonly implemented in buck converter circuits, which are used to step down voltage efficiently from a higher voltage level to a lower voltage level.

Detailed Circuit Connection:

1. Placement of LQH32CN4R7M33L: In a buck converter, the LQH32CN4R7M33L is usually placed in series with the output. Connect the source voltage to the first terminal of the LQH32CN4R7M33L (pin 1), and connect its second terminal (pin 2) to the drain of the switching MOSFET.

2. MOSFET Integration: A MOSFET acts 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: Connect an output capacitor in parallel with the load to the second terminal of the LQH32CN4R7M33L. This capacitor helps in smoothing out the output voltage.

4. Feedback and Regulation: 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 Rating Compliance: Make sure that the current passing through the LQH32CN4R7M33L does not exceed 680mA to avoid core saturation and potential damage.

- Heat Dissipation Management: Given its 0.12Ω resistance, the LQH32CN4R7M33L will generate heat and thus require adequate thermal management, particularly in compact designs or high-power applications.

- Frequency Consideration: The LQH32CN4R7M33L operates efficiently at certain 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 LQH32CN4R7M33L 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 essence, the LQH32CN4R7M33L 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 LQH32CN4R7M33L necessitate a comprehensive understanding of the circuit's requirements, considering factors such as power handling, thermal management, and the spatial arrangement of components.
