4120R-601-101/201L

Overview

The Bourns 4120R-601-101/201L is an eight-channel RC T-type EMI filter designed for electromagnetic interference suppression. It features a resistance value of 100 Ohms and a capacitance of 200 pF per channel. The component utilizes a 20-pin DIP package with a 0.300-inch (7.62mm) body width. Termination style is through-hole, suitable for standard PCB mounting.

Feature Summary

• Eight independent channels for multi-line signal filtering
• T-type RC network topology for effective noise attenuation
• Through-hole DIP packaging for robust mechanical stability

Applications

• General-purpose electronic equipment EMI suppression
• Multi-channel data line protection
• Signal integrity enhancement in noisy environments

Procurement Notes

Verify the exact suffix /201L against the manufacturer's current datasheet to confirm pinout and tolerance specifications. Check for obsolete status or lifecycle changes before finalizing procurement plans. Ensure compatibility with existing PCB footprints and assembly processes.

Selection Notes

Select this component when eight-channel low-pass filtering is required for digital or analog signals. The 100 Ohm resistance and 200 pF capacitance define the cutoff frequency characteristics. Consider thermal management and physical space constraints associated with the 20-DIP package during design integration.

Part Context

This part belongs to the Bourns 4120R series of RC networks. These components are engineered for compact EMI/RFI filtering solutions. The series offers various resistance and capacitance combinations to suit different signal frequencies and impedance requirements across multiple channels.

Replacement Considerations

Consult official Bourns documentation for direct substitutes. Verify that any alternative maintains the same 8-channel configuration, 100 Ohm resistance, 200 pF capacitance, and 20-DIP footprint to ensure functional equivalence.
