4420P-601-470/201L

Overview

The Bourns 4420P-601-470/201L is an 8-channel RC (T-Type) EMI filter network designed for surface-mount applications. It features a 20-SOIC package with a 7.50mm width. The component provides general-purpose low-pass filtering with a rated voltage of 25V. Each channel integrates a 47 Ohm resistor and a 200pF capacitor, forming a first-order filter structure to suppress electromagnetic interference in signal lines.

Feature Summary

• Provides eight independent channels for simultaneous signal conditioning within a single compact package.
• Utilizes T-type RC network topology to achieve effective low-pass filtering characteristics.
• Designed for surface-mount technology to facilitate automated assembly processes.

Applications

• General-purpose electromagnetic interference suppression
• Signal line protection in electronic circuits
• Low-pass filtering for data transmission lines

Procurement Notes

Verify the specific suffix designation carefully, as variations exist within the series. Confirm that the 47 Ohm resistance and 200pF capacitance values match the circuit requirements exactly. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the 20-SOIC footprint dimensions are compatible with the printed circuit board layout constraints.

Selection Notes

Select this component when multiple signal lines require identical low-pass filtering characteristics. The integrated design reduces board space compared to discrete components. Verify that the 25V rated voltage exceeds the maximum operating voltage of the signals being filtered. Consider the thermal performance and power dissipation capabilities relative to the expected current loads in the application environment.

Part Context

This part belongs to the Bourns 4420P series of resistor networks. The series offers various resistance and capacitance combinations to suit different frequency response needs.
