4420P-601-101/101

Overview

The Bourns Inc. 4420P-601-101/101 is an RC (T-Type) EMI filter circuit designed for surface mount applications. It features a first-order low-pass configuration with eight independent channels. Each channel integrates a resistor of 100 Ohms and a capacitor of 100 picofarads to suppress electromagnetic interference. The component is housed in a 20-SOIC package with a width of 7.50 mm. It operates within a temperature range of -10°C to 85°C and does not include electrostatic discharge protection.

Feature Summary

• Eight-channel T-type RC network architecture for multi-line signal conditioning
• First-order low-pass filtering topology integrated into a single surface-mount package
• Fixed 100 Ohm resistance and 100 picofarad capacitance per channel for consistent attenuation characteristics

Applications

• Electromagnetic interference suppression in high-density digital circuits
• Signal integrity management in data transmission lines
• Noise reduction in multi-channel peripheral interfaces

Procurement Notes

Verify the specific suffix designation, as variants such as the 4420P-601-101/101L are documented as end-of-life products by the manufacturer. Confirm current availability status through authorized distributors, as discontinuation notices may affect supply chain stability. Ensure the ordering part number matches the required tolerance and packaging specifications exactly.

Selection Notes

Select this component when a compact, multi-channel solution is required for first-order low-pass filtering without the need for discrete component placement. The fixed 100 Ohm and 100 picofarad values suit applications requiring specific cutoff frequencies for noise suppression. Consider the 20-SOIC footprint for board space constraints and verify that the absence of built-in ESD protection aligns with the system's overall safety requirements.

Part Context

This component belongs to the Bourns 4420P series of RC filter networks. These devices are engineered to provide reliable EMI/RFI suppression in electronic systems where multiple signal lines require simultaneous filtering. The series utilizes standard resistor-capacitor topologies integrated into monolithic packages to simplify assembly and improve consistency across production runs.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific model are not available in the provided documentation. Verify compatibility with alternative RC networks based on channel count, package dimensions, and electrical parameters before substitution.
