CM3032V301R-10 Filters

Common Mode Chokes (CMCs) are electromechanical devices used in a variety of electrical circuits or applications. They are designed to suppress or block high or wide frequency noise that is transmitted through a power conductor to a load, such as an electronic device or a control system. The CM3032V301R-10 is a type of CMC manufactured by Murata Power Solutions. This particular CMC is a surface mount ¾” by ½”, 10 turn choke designed to suppress common mode currents in applications with high power applications.

The significance of common mode current is that it can generate disruptive EMI (electromagnetic interference) that can interfere with the proper function of an electronic device or system. The CM3032V301R-10 is thus designed to suppress the common mode current generated by the power supply or other equipment and provide a high level of protection against unwanted EMI.

The application field of the CM3032V301R-10 is quite wide. It can be used in wireless communication systems, computer power supplies, intelligent instrumentation, lighting systems and LED lighting, automotive electronics, motor drives, industrial control, medical equipment, inverter equipment, and consumer electronics.

The working principle of the CM3032V301R-10 is based on the concept of impedance matching. It works by providing a low impedance path for the high frequency signals or noise while providing a high impedance path for the lower frequency signals. By providing this impedance mismatch, the unwanted EMI is effectively blocked while the useful signals are kept intact. The CM3032V301R-10 also provides a special type of shielding that limits the radiation field and reduces EMI radiation in the surrounding area.

The CM3032V301R-10 is rated for use in temperatures ranging from -40°C to 85°C with an operating voltage range from 5 to 300 VDC. It has an insertion loss of 0.4 dB at 100 MHz and a frequency range from 10 kHz to 200 MHz. The product comes with several safety features to ensure reliable operation, such as thermal protection, reverse polarity protection, and inrush current protection.

The CM3032V301R-10 is an excellent choice for high power applications requiring a high degree of EMI protection. Its wide application field and advanced working principle make it an ideal choice for protecting electronic devices and systems.
