The LDB15C201A1500 is a Murata common mode choke. Common mode chokes are electronic components designed to suppress common-mode noise in electronic circuits. They are commonly used in various applications to improve signal integrity and reduce electromagnetic interference (EMI). They are constructed with two identical inductors wound on a single core, such that the magnetic fields generated by differential-mode currents cancel each other out, while the magnetic fields generated by common-mode currents add together, creating a high impedance to common-mode noise.

Applications

• USB lines to filter common-mode noise.
• LVDS interfaces for signal integrity improvement.
• Power lines to suppress noise entering or leaving a device.
• Ethernet interfaces to meet EMI/EMC compliance requirements.
• Audio circuits to reduce unwanted noise and improve sound quality.

Features

• High common mode impedance
• Low differential mode impedance
• Compact size
• High current handling capability
• RoHS compliant

Benefits

• Effective suppression of common mode noise
• Minimal impact on differential mode signals
• Space-saving design for high-density applications
• Handles significant current without saturation
• Environmentally friendly

Additional Details

The LDB15C201A1500 is typically surface mountable. The specific inductance and impedance values can be found in the Murata datasheet. These chokes contribute to meeting stringent EMI/EMC regulations, improving the reliability and performance of electronic devices. Selection of a common mode choke depends on factors such as the frequency range of the noise, the required impedance, the current rating, and the physical size constraints. This part is often used to suppress noise generated by switching power supplies, microprocessors, and other digital circuits. Its compact size makes it suitable for integration into portable devices and other space-constrained applications.
