4420P-601-250/101

Overview

The Bourns Inc. 4420P-601-250/101 is an eight-channel RC (T-Type) EMI filter circuit designed for surface-mount applications. It functions as a first-order low-pass filter to suppress electronic noise in signal lines. The component features integrated resistors with a nominal value of 25 ohms and capacitors rated at 100 picofarads per channel. This configuration provides effective attenuation of high-frequency interference while maintaining signal integrity across multiple channels within a compact footprint.

Feature Summary

• Eight-channel T-type RC network architecture for multi-line filtering
• First-order low-pass response for electronic noise suppression
• Surface-mount design for automated assembly integration

Applications

• Signal line filtering in electronic equipment
• EMI suppression in data transmission interfaces
• Noise reduction in professional audio signal paths

Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number may be discontinued or subject to limited availability. Confirm that the RoHS non-compliant status aligns with your manufacturing regulations. Ensure the surface-mount package dimensions match your PCB layout requirements. Validate that the 25-ohm resistance and 100-picofarad capacitance values meet the circuit design specifications for the intended application.

Selection Notes

Select this component when multi-channel EMI filtering is required in a compact form factor. The T-type RC topology offers a balance between insertion loss and signal attenuation. Consider the surface-mount package type for automated placement processes. Evaluate the electrical parameters against the target frequency range to ensure adequate noise suppression without excessive signal degradation.
