Fixed inductors, also known as "choke coils" or "coils," are electrical components commonly used in AC power supplies, power filtering networks, and other sensitive signal or power conditioning applications. The LQH32MN1R2M23L is a fixed inductor from Murata Electronics, specifically designed for common mode noise suppression

Application Field

The LQH32MN1R2M23L is a fixed inductor specifically designed for common mode noise suppression in digital signal lines and peripheral buses. It boasts low cost, low DC resistance, high reliability, and small size. This makes the LQH32MN1R2M23L ideal for digital processor applications and communication circuits, including wireless communication, radio systems, automotive navigation equipment, surveillance cameras, video game consoles, and more.

The small size of the LQH32MN1R2M23L makes it easy to mount in small devices and systems with limited space. Additionally, the low DC resistance minimizes power losses. In systems where thermal accuracy is essential, such as automotive systems, the wide temperature range (-40 to +125 degrees Celsius) of the LQH32MN1R2M23L helps to ensure stable operation over a variety of environmental conditions.

Working Principle

Fixed inductors use the property of inductance, which is a fundamental property of all electric fields. When a voltage is applied across an inductor, a current is produced when electric magnetic fields interact. The amount of current is proportional to the amount of voltage applied. By increasing the number of turns in the inductor coil, the amount of inductance can be increased, thus increasing the effectiveness of the inductor in noise suppression.

The LQH32MN1R2M23L is a double-wound, high-inductance monolith inductor. It uses two coils with the same number of turns, wound in opposite directions. This increases the inductance of the device without increasing its physical size, allowing it to provide better noise suppression in small spaces. Additionally, the core material provides additional shielding, further reducing conducted and radiated noise.

The LQH32MN1R2M23L also has frequency characteristics optimized for digital systems. The frequency response is not constant, but varies depending on the current. This helps reduce noise in digital systems by allowing the inductor to pass higher frequency signals while simultaneously blocking the transmission of lower frequency signals that may contain noise.

The LQH32MN1R2M23L is thus ideal for applications that need effective noise suppression without significantly increasing power consumption or the device’s physical size. The two coils combined with the optimized frequency response and shielding allow the device to provide reliable noise suppression in applications with high levels of electrical interference.
