RI4184

Overview

The Ranatec RI4184 is a dual USB 2.0 feedthrough filter designed for high-performance EMI/RFI suppression in applications requiring USB signal integrity. It supports two independent USB channels, each capable of supplying up to 2 A of current to connected devices. The component operates at data rates up to 480 Mbps, adhering to the USB 2.0 standard. As a passive LC network filter, it provides second-order band-pass filtering characteristics across four channels to mitigate electromagnetic interference while maintaining signal quality.

Feature Summary

• Dual-channel architecture supporting simultaneous connection of two USB devices
• Integrated EMI/RFI suppression using passive LC network technology
• High current capacity with 2 A supply capability per channel
• Panel-mountable design for secure mechanical integration

Applications

• Industrial control systems requiring isolated USB connectivity
• Medical equipment needing compliant USB interfaces
• Automotive infotainment and diagnostic ports
• Test and measurement instrumentation

Procurement Notes

Verify that the specific order matches the RI4184 part number, as Ranatec offers related variants such as the single-channel RI4185. Confirm panel mounting requirements and ensure compatibility with existing chassis designs. Check for any specific environmental ratings if operating in extreme conditions. Request official datasheets to validate electrical specifications against system requirements before finalizing procurement.

Selection Notes

Choose the RI4184 when dual USB 2.0 isolation is required within a single compact footprint. Select this model over the RI4185 if two separate device connections are necessary. Ensure the application does not exceed the 480 Mbps data rate limit or the 2 A current rating per channel. Consider mechanical constraints regarding panel thickness and mounting hole dimensions during the selection process.

Part Context

The RI4184 belongs to Ranatec's family of shielded feedthrough filters, which also includes the single-channel RI4185 and SuperSpeed USB 3.0 variants like the RI4192. These components are engineered for environments where electromagnetic compatibility is critical. The series utilizes passive filtering techniques to protect sensitive electronics from external noise while preventing internal emissions from affecting other systems.

Replacement Considerations

The Ranatec RI4185 serves as a functional substitute if only a single USB channel is needed, offering identical filtering performance but with reduced I/O capacity. No third-party cross-references are publicly confirmed for this specific dual-channel configuration.
