Overview
The Bourns Inc. 4420P-601-250/181 is a surface-mount EMI filter circuit belonging to the 601 Series. It utilizes an RC (T-Type) network topology designed for signal line protection. The component features a rated voltage of 25V and integrates specific passive values: a resistance of 25 Ohms and a capacitance of 180 pF. It is housed in a 20-SOIC package with dimensions of 0.510 inches in length and 0.295 inches in width. This device functions as a low-pass filter to attenuate high-frequency noise.
Feature Summary
- Integrates a T-type RC network structure for compact signal filtering applications
- Provides low-pass filtering characteristics to suppress electromagnetic interference
- Designed for surface-mount assembly using standard SOIC footprint
Applications
- Signal line EMI suppression in electronic circuits
- High-frequency noise attenuation in data transmission paths
- Component integration within surface-mount PCB designs requiring compact filtering
Procurement Notes
Verify current availability status as this component may be subject to discontinuation or limited distribution channels. Confirm that the 20-SOIC package dimensions align with your PCB layout constraints. Ensure the 25V rated voltage meets the operational requirements of your target circuit environment before finalizing procurement decisions.
Selection Notes
Select this component when a compact, surface-mount solution is required for low-pass filtering on signal lines. The 25 Ohm resistance and 180 pF capacitance define its cutoff characteristics. Consider the 20-SOIC package size for board space limitations. Verify compatibility with automated pick-and-place equipment due to the specific reel packaging format.
Part Context
This part belongs to the Bourns 601 Series of EMI filter circuits. These components are engineered to provide reliable noise reduction in sensitive electronic systems. The series offers various configurations tailored for different impedance and capacitance requirements while maintaining a consistent surface-mount form factor for modern manufacturing processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official manufacturer resources for direct replacements or equivalent alternatives from other suppliers.
