SM28R1133

Overview

The SM28R1133 is a solid flat ribbon cable ferrite core manufactured by LeaderTech. It features a hinged snap-on design for easy installation on cables without disconnection. The component is constructed from material designated as type 28, optimized for high-frequency noise suppression. It operates with an impedance of 245 Ohms measured at a test frequency of 100 MHz. The physical dimensions include an internal length of 52.1 mm and an external length of 58.4 mm. The external width is 28.6 mm, while the external height measures 8.4 mm. Internal height is specified at 1.3 mm. The product is supplied in bulk packaging.

Feature Summary

• Hinged snap-on construction allows for quick attachment to existing cable assemblies.
• Solid flat geometry designed specifically for ribbon cable applications.
• Utilizes type 28 ferrite material for effective electromagnetic interference suppression.

Applications

• Noise suppression on flat ribbon cables in electronic equipment
• Electromagnetic interference filtering in data transmission lines
• Cable assembly protection in industrial control systems

Procurement Notes

Verify the specific impedance value and material composition against the official LeaderTech datasheet before integration. Confirm that the hinged mechanism meets the mechanical retention requirements of the target assembly. Ensure compatibility with the ribbon cable thickness and width specifications. Check RoHS compliance status through the manufacturer's documentation. Validate the test frequency parameters for the intended application environment.

Selection Notes

Select this component when a non-invasive solution for ribbon cable noise reduction is required. The snap-on feature simplifies assembly compared to split cores that require fasteners. Consider the 245 Ohm impedance rating for matching the frequency range of the signals being filtered. Evaluate the physical envelope to ensure it fits within the available space constraints of the device chassis.
