Overview
The Bourns Inc. 4118R-601-101/201L is a through-hole RC network filter belonging to the 601 series. It features a T-type configuration with a resistance of 100 Ohms and capacitance of 200 pF, rated for 25V. The component measures 0.965 inches in length by 0.300 inches in width (24.51mm x 7.62mm). Designed as a low-pass filter, it provides EMI/RFI suppression capabilities. This product is currently no longer manufactured.
Feature Summary
- Provides low-pass filtering functionality for signal integrity
- Utilizes a T-type RC network topology for noise reduction
- Constructed for through-hole mounting applications
Applications
- EMI/RFI suppression circuits
- Signal conditioning networks
- Low-pass filtering applications
Procurement Notes
This component is officially discontinued and no longer manufactured by Bourns Inc. Verification of availability should focus on surplus or secondary market sources rather than direct production channels. Confirm RoHS3 compliance status if required for specific regulatory environments. Ensure substitute components meet identical electrical specifications for resistance, capacitance, and package dimensions to maintain circuit performance.
Selection Notes
Select this part only if legacy compatibility is required, as it is end-of-life. Verify that the 100 Ohm resistance and 200 pF capacitance values align precisely with the original design requirements. Consider the physical footprint of 0.965" L x 0.300" W during PCB layout planning. Evaluate alternative modern equivalents from the same manufacturer family if new production is necessary.
Part Context
The 4118R-601-101/201L belongs to Bourns' 601 series of discrete RC networks. These components are designed for general-purpose EMI/RFI filtering in electronic assemblies. The series offers various resistance and capacitance combinations within a standardized DIP-style package format, facilitating easy integration into existing circuit designs requiring passive noise suppression.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the component is discontinued, engineers must identify equivalent RC networks with matching 100 Ohm/200 pF specifications and compatible through-hole packaging from other manufacturers or newer Bourns series.
