4420P-601-250/500L

Overview

The Bourns Inc. 4420P-601-250/500L is an EMI filter circuit belonging to the RC (T) network series. It features a surface-mount package with dimensions of 0.510 inches in length, 0.295 inches in width, and 0.114 inches in height. The component provides a resistance value of 25 ohms and a capacitance value of 50 picofarads.

Feature Summary

Provides electromagnetic interference filtering through an integrated RC T-network topology.

Applications

General electronic equipment requiring EMI suppression

Procurement Notes

This component is officially discontinued and no longer manufactured by Bourns Inc. Verification of availability should focus on surplus or secondary market sources rather than direct factory orders. Designers must confirm end-of-life status before finalizing specifications for new production runs.

Selection Notes

Engineers seeking alternatives should evaluate other components within the Bourns 4420P series that offer similar RC network configurations. Selection criteria should prioritize matching the required impedance characteristics and physical footprint constraints of the original design while ensuring current manufacturing availability.

Part Context

The 4420P series consists of surface-mount EMI filters designed for compact applications. This specific model utilizes a 20-SOIC package style, integrating passive components into a single unit to save board space compared to discrete implementations.

Replacement Considerations

Public confirmed substitute part numbers are not available due to the product's discontinuation status. Engineers must identify functionally equivalent RC networks from current active product lines.
