The NFM840R01G470T1M00-63 is a Murata Electronics North America common mode choke. Common mode chokes are used to suppress common mode noise in electronic circuits, preventing interference from affecting the performance of the device or radiating to other devices.

Applications:

• USB interfaces
• HDMI interfaces
• LVDS lines
• Power line filtering
• Signal line noise suppression

Features:

• High Common Mode Impedance
• Low Differential Mode Impedance
• Small Size
• Surface Mount Device (SMD)
• RoHS Compliant

Benefits:

• Effective suppression of common mode noise improves signal integrity and reduces electromagnetic interference (EMI).
• Minimal impact on differential signals ensures that desired signals are not attenuated.
• The small size allows for placement in tight spaces on circuit boards.
• Surface mount design simplifies assembly processes and reduces manufacturing costs.
• RoHS compliance ensures that the component is environmentally friendly.

Technical Specifications:

The NFM840R01G470T1M00-63 has a common mode impedance of 47 Ohms at 100 MHz. The rated current is typically in the hundreds of milliamperes (mA), and the operating temperature range is generally from -40°C to +85°C. It comes in a small surface-mount package, making it suitable for high-density circuit boards. It is designed to filter out unwanted noise while allowing the desired signals to pass through with minimal distortion. These chokes are critical in ensuring electromagnetic compatibility (EMC) in electronic devices.
