4420P-601-820/201

Overview

The Bourns 4420P-601-820/201 is an RC (T-Type) EMI filter circuit designed for surface-mount applications. It features eight independent channels, each configured with a resistance of 82 Ohms and capacitance of 200 pF to form first-order low-pass filters. 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 is rated for 25V. This device suppresses electromagnetic interference in electronic circuits.

Feature Summary

• Eight-channel RC network configuration for multi-line signal filtering
• Surface-mount design compatible with automated assembly processes
• First-order low-pass filtering characteristics for EMI suppression

Applications

• Electromagnetic interference suppression in electronic devices

Procurement Notes

Verify the specific suffix and tolerance requirements against the official datasheet before procurement. Confirm that the 20-SOIC footprint matches the target PCB layout. Ensure the operating temperature range meets the environmental specifications of the final application. Check for RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when eight isolated low-pass filter paths are required in a compact surface-mount package. The 82 Ohm resistance and 200 pF capacitance values define the cutoff frequency characteristics. Consider the 25V rating and thermal limits during system design. Verify compatibility with existing board space constraints due to the SOIC package dimensions.
