4420P-T06-250/500L

Overview

The Bourns 4420P-T06-250/500L is an RC (T-Type) EMI filter designed for surface mount applications. It integrates eight channels of filtering within a single package, featuring a resistance value of 25 Ohms and a capacitance of 50 pF per channel. The component utilizes a wide-body 20-SOIC footprint with a width of 7.50 mm (0.295 inches). This configuration supports first-order low-pass filtering characteristics to mitigate electromagnetic interference in high-density circuit designs.

Feature Summary

• Integrates eight independent filtering channels in a compact surface-mount package
• Provides first-order low-pass attenuation for signal integrity enhancement
• Utilizes T-type RC network topology for effective noise suppression

Applications

• High-speed digital interface protection
• Data line EMI suppression in consumer electronics
• Signal conditioning for communication ports

Procurement Notes

Verify the specific suffix 'L' indicates lead-free compliance and RoHS status against current manufacturer declarations. Confirm the package dimensions match the 20-SOIC wide-body specification. Ensure the resistance and capacitance values align with the design requirements for the target frequency range. Check for any end-of-life notifications or alternative recommendations from Bourns Inc.

Selection Notes

Select this component when multi-channel EMI filtering is required in space-constrained layouts. The integrated nature reduces board space compared to discrete components. Ensure the operating voltage and current ratings exceed the application's maximums. Consider the thermal performance of the wide-body package if significant power dissipation is expected during operation.

Part Context

This part belongs to Bourns' family of RC network filters, specifically designed for EMI suppression. The 4420P series offers various resistance and capacitance combinations to suit different impedance matching and filtering needs. These components are commonly used in data lines where signal integrity must be maintained while attenuating high-frequency noise.

Replacement Considerations

Consult Bourns official documentation for direct pin-compatible substitutes with identical electrical parameters. Verify that any alternative maintains the same 8-channel configuration and 20-SOIC wide-body package dimensions. Cross-reference tolerance and temperature coefficient specifications to ensure equivalent performance.
