The NFA21SL307V1A45L is a common mode choke from Murata Electronics North America. Common mode chokes are electronic components used to suppress common-mode noise in electronic circuits. Common-mode noise is unwanted electrical noise that appears equally on multiple signal lines with respect to ground. This choke is designed to attenuate that noise, improving signal integrity and reducing electromagnetic interference (EMI).

Applications:

• Suppression of common-mode noise in differential signal lines
• USB lines
• HDMI lines
• Ethernet lines
• Audio lines

Features:

• Compact size (2.0mm x 1.2mm)
• High common-mode impedance
• Low differential-mode impedance
• Surface mount device (SMD)
• Excellent noise suppression characteristics
• RoHS Compliant

Benefits:

• Reduced electromagnetic interference (EMI)
• Improved signal integrity
• Enhanced performance of electronic devices
• Simplified PCB layout due to its small size
• Easy to integrate into automated assembly processes
• Environmentally friendly due to RoHS compliance

The NFA21SL307V1A45L common mode choke is specifically designed for applications where minimizing both size and noise are critical. Its low differential-mode impedance ensures that the desired signal passes through with minimal attenuation, while the high common-mode impedance effectively blocks unwanted noise. Murata is a well-known and trusted manufacturer of electronic components and this part will reliably reduce noise in many applications.
