MB1350

Power Line Filter Modules

MB1350 is an advanced power line filter module that is designed to reduce electromagnetic interference (EMI) from electrical and electronic systems. This filter module is primarily used in power supplies, electric motors, and other equipment that generate high levels of noise. The MB1350 is an all-in-one filter module offering both line-to-chassis shielding and common-mode EMI filtering.

Application Field

The MB1350 is designed to reduce the amount of EMI produced by power supplies, electric motors, and other power-related equipment. The module is ideally suited for applications in computers, telecom equipment, HVAC, medical equipment, and industrial machinery. It can also be used in consumer appliances and home entertainment devices. In addition, the MB1350 can be used in various power-supply designs, including switched-mode power supplies, pulse-width modulators, and boost converters.

Working Principle

The MB1350 utilizes a series-pass capacitor-input filter design for EMI reduction. This design generally consists of two common-mode inductors and a series of capacitors. This combination of components allows the MB1350 to attenuate high-frequency electromagnetic noise to meet the requirements of CISPR-11 and CISPR-16-2-1. The filter provides a low-impedance ground path for EMI surges and reduces their effect. In addition, the filter also provides an effective shielding effect and suppresses the transfer of EMI from one circuit to another.

The MB1350 also utilizes an integrated line-to-chassis shielding feature. This feature helps to contain the EMI so that it is not transferred from the power line to any other area of the system. The integrated line-to-chassis shielding offers improved performance compared to traditional solutions, making it a more reliable and cost-effective option.

In addition, the MB1350 offers a range of input-voltage protection, including transient protection, over-voltage protection, and ESD protection. These features ensure that the module and its components remain operational in the presence of high voltage.

Overall, the MB1350 is an excellent power line filter module that offers efficient EMI reduction and line-to-chassis shielding. The module provides reliable protection and can help reduce costs associated with meeting electromagnetic compatibility requirements.
