Frequently Asked Questions

What current and voltage ratings does the NFE31PT221D1E9L support?

The NFE31PT221D1E9L is rated for 6A continuous current and 25V working voltage. These ratings make it suitable for data-line filtering on interfaces such as USB 3.x and HDMI where both signal integrity and moderate current capacity are required.

How does the built-in ferrite bead help in the NFE31PT221D1E9L filter design?

The T-type circuit integrates a ferrite bead that adds inductive impedance in series with the data line, effectively blocking high-frequency noise above 100 MHz while passing the intended signal. Combined with the 220pF shunt capacitance, this forms a low-pass LC network that suppresses both common-mode and differential-mode EMI.

Is the NFE31PT221D1E9L suitable for high-speed USB or HDMI data lines?

Yes. The NFE31PT221D1E9L is classified as a data-line filter with a 220pF capacitance and 6A rating, making it appropriate for USB 2.0/3.0 and HDMI interfaces. Engineers should verify the filter's impedance curve against the specific data rate to ensure insertion loss remains within acceptable limits, typically below 1 dB at signal frequencies.

What package dimensions does the NFE31PT221D1E9L use, and how does that affect board layout?

The NFE31PT221D1E9L uses a surface-mount package with 1.6mm height, occupying minimal PCB area. This compact SMD footprint allows placement directly in the data signal path close to connectors, minimizing stub lengths and preserving signal integrity on high-speed interfaces.
