4420P-601-820/201L

Overview

The Bourns 4420P-601-820/201L is a surface-mount EMI filter circuit belonging to the 601 series. It functions as an RC (T) network low-pass filter with eight channels, providing R = 82 Ohms and C = 200 pF per channel. The component operates within a voltage rating of 25V and an operating temperature range of 10°C to 85°C. It is housed in a 20-SOIC package with a width of 7.50mm.

Feature Summary

• Eight-channel RC T-network configuration for multi-line signal filtering
• Surface-mount design compatible with automated assembly processes
• Low-pass filtering capability for EMI/RFI suppression

Applications

• Multi-channel data line protection
• Signal integrity enhancement in high-speed interfaces

Procurement Notes

Verify the specific suffix 'L' against the manufacturer's current datasheet to confirm packaging details and compliance status. Check for end-of-life notifications or discontinuance alerts, as availability may be limited. Ensure the selected variant matches the required resistance and capacitance values for the target application.

Selection Notes

Select this component when eight independent low-pass filters are required in a single surface-mount package. Confirm that the 82 Ohm resistance and 200 pF capacitance meet the cutoff frequency requirements. Verify that the 25V rating and SOIC footprint fit the board layout constraints.

Part Context

This part belongs to Bourns' 601 series of EMI filter circuits. These components are designed for suppressing electromagnetic interference in digital signal lines. The series offers various resistance and capacitance combinations to suit different filtering needs while maintaining a compact form factor.

Replacement Considerations
