Additional Details

The NFM61T20T472T1M00 common mode choke utilizes a ferrite core and a balanced winding configuration to achieve its high common mode impedance and low differential mode impedance. The choke effectively attenuates common mode noise while allowing differential signals to pass through with minimal attenuation. This improves signal integrity and reduces the risk of EMI.

Technical Specifications (Typical):

• Inductance: 4700 µH
• Common Mode Impedance: 2000 Ohms (at 100 MHz)
• Differential Mode Impedance: 5 Ohms (at 100 MHz)
• Rated Current: 1000 mA
• DC Resistance (DCR): 0.2 Ohms
• Operating Temperature: -40°C to +85°C

The NFM61T20T472T1M00 is available in a standard surface mount package, making it easy to integrate into automated assembly processes. Its robust design and high-performance characteristics make it an excellent choice for common mode noise suppression in high-speed data interfaces.
