Overview
The Bourns 4420P-T06-250/201L is a Surface Mount EMI filter circuit belonging to the 601 series. It utilizes an RC (T) network topology designed for signal integrity protection. The component features a wide body SOIC-20 package with 300-mil spacing, accommodating multiple filtering channels in a compact form factor. It operates within a temperature range of -10°C to +85°C and supports a maximum voltage rating of 25V. Key electrical specifications include a resistance value of 25 ohms and a capacitance of 200 picofarads per channel, providing attenuation characteristics such as 3dB at 21MHz.
Feature Summary
- Integrates RC T-network filtering topology for effective EMI suppression
- Utilizes thick film technology on a wide body surface mount substrate
- Provides multi-channel signal conditioning within a single compact package
Applications
- High-speed digital signal line protection
- EMI suppression in data communication interfaces
- Signal integrity enhancement in consumer electronics
Procurement Notes
This specific part number is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate that Mouser Electronics does not currently stock this item in relevant regions. Verification of availability should focus on secondary market suppliers or authorized distributors holding remaining inventory, as direct new production supply is discontinued.
Selection Notes
Designers requiring this specific RC configuration must account for the component's discontinuation status. Selection should prioritize verifying the exact package dimensions and electrical parameters against current design requirements. Due to the EOL status, alternative sourcing strategies or redesign efforts using available equivalent components are necessary for ongoing production needs.
Part Context
The 4420P series represents Bourns' lineup of surface mount resistor networks and EMI filters. This specific model falls under the category of EMI/RFI filters utilizing RC networks. It is engineered for applications demanding compact footprint solutions while maintaining signal quality through integrated passive filtering elements within a standardized SOIC-style housing.
Replacement Considerations
As the 4420P-T06-250/201L is discontinued, no official direct substitute part numbers are confirmed in public documentation. Engineers should evaluate other Bourns 601 series variants or generic RC filter arrays that match the required 25-ohm resistance and 200-pF capacitance values within compatible packages.
