EPCOS - TDK Electronics B82793C0113N201 Environmental and export classification status description

Overview The TDK Electronics B82793C0113N201 is a common-mode choke inductor designed to provide effective noise suppression and filtering in electronic circuits. It is part of the Electronic Filters category and is commonly used to reduce electromagnetic interference (EMI) in power lines and signal lines. Functions 1. Suppressing common-mode noise: The choke inductor filters out unwanted common-mode noise by impeding its flow along the power or signal lines. 2. Improving signal quality: By reducing interference, the common-mode choke can help improve the quality and reliability of signals in electronic circuits. Applications 1. Power supply filtering: Common-mode chokes are used to filter noise and improve the efficiency of power supplies. 2. Signal and data lines: They can be used in communication systems and data lines to reduce interference and enhance signal integrity. 3. Electric vehicles: Common-mode chokes are employed in electric vehicles to minimize EMI and maintain the reliability of critical systems. Alternative Components 1. Ferrite beads: These are similar to common-mode chokes and are often used for EMI suppression in electronic circuits. 2. RFI filters: Radio-frequency interference filters can also provide noise suppression in electronic systems. 3. Capacitors: Capacitors can be used in conjunction with inductors for more comprehensive filtering. Embedded Modules The common-mode choke may be integrated into larger modules or devices that require noise suppression, such as power supplies, motor drives, or communication equipment. Related Q&A 1. Q: How does a common-mode choke differ from a differential-mode choke? A: A common-mode choke filters noise that appears in common on both conductors, while a differential-mode choke suppresses noise that appears differentially between the conductors. 2. Q: What are the benefits of using a common-mode choke in a power supply? A: Common-mode chokes can help reduce EMI, improve power quality, and protect sensitive equipment from noise and interference. 3. Q: Can common-mode chokes be used in audio applications? A: Yes, common-mode chokes can be beneficial in audio applications to reduce noise and interference for clearer sound quality. 4. Q: How do you select the right common-mode choke for a specific application? A: Factors such as current rating, impedance characteristics, and frequency range should be considered when choosing a common-mode choke for a particular application. 5. Q: Are there any standards or guidelines to follow when incorporating common-mode chokes in electronic designs? A: Yes, there are industry standards and guidelines that recommend the use of common-mode chokes for EMI suppression in various electronic systems.
