Würth Elektronik 744232090

The Würth Elektronik 744232090 is a common-mode choke designed for noise suppression in differential signaling applications. It is primarily used in various electronic circuits to reduce electromagnetic interference (EMI) and improve signal integrity. Functions - Noise Suppression: The choke filters out high-frequency noise that can affect the performance of sensitive electronic components. - Impedance Matching: It helps in achieving better impedance matching in signal transmission lines. - EMI Filtering: The component reduces electromagnetic interference by filtering common-mode signals, which are noise that appears equally on both lines of a differential pair. Applications - Data Communication: Commonly used in Ethernet, USB, and other data transmission standards where signal integrity is crucial. - Power Supply Filtering: Useful in power supply circuits to filter out noise that could affect the performance of the power system. - Consumer Electronics: Employed in devices like televisions, audio equipment, and mobile devices to improve overall performance and compliance with EMI standards. Alternative Parts 1. Bourns SRR-120-220M: Another common-mode choke with similar filtering capabilities that could be used in various applications. 2. Murata 7446: A ferrite core common-mode choke for differential pairs, suitable for EMI suppression. 3. Taiyo Yuden BK085CM330: A compact common-mode choke that provides effective noise suppression. Embedded Modules Würth Elektronik also offers a range of embedded modules that can integrate common-mode chokes into PCB designs, making it easier for engineers to include noise filtering in their systems. Q&A Q1: What is the primary purpose of the Würth Elektronik 744232090? A1: The primary purpose of the Würth Elektronik 744232090 is to filter out high-frequency noise from differential signals, thereby improving signal integrity and reducing electromagnetic interference (EMI). Q2: In which applications is the Würth Elektronik 744232090 typically used? A2: It is typically used in data communication applications such as Ethernet and USB connections, power supply noise filtering, and various consumer electronics to ensure better performance and compliance with EMI standards. Q3: How does a common-mode choke differ from a regular inductor? A3: A common-mode choke is specifically designed to suppress noise that appears equally on both conductors of a differential signal, while a regular inductor does not have this filtering capability for common-mode signals and is generally used for energy storage or filtering in different contexts. Q4: Are there alternative products similar to the Würth Elektronik 744232090? A4: Yes, alternatives include components like the Bourns SRR-120-220M, Murata 7446, and Taiyo Yuden BK085CM330, which offer similar functions of EMI suppression and signal integrity improvement. Q5: What design considerations should be taken into account when using the 744232090 in a PCB layout? A5: When integrating the 744232090 into a PCB layout, consider factors such as the layout's grounding strategy, the proximity to noisy components or traces, the trace impedance, and ensuring the common-mode choke is placed in series with the differential signal lines to effectively filter noise.
