27A2024-0A2

Overview

The 27A2024-0A2 is a hinged snap-on ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 260 Ohms at 100 MHz. The component features a circular inner diameter of 0.514 inches (13.06 mm). Its outer dimensions are 1.142 inches in width and 1.166 inches in height, corresponding to 29.01 mm x 29.66 mm. The material designation for this core is Material 27.

Feature Summary

• Hinged snap-on design allows installation around existing cables without disconnection
• Provides high impedance attenuation for common mode noise suppression
• Constructed from Material 27 optimized for specific frequency filtering

Applications

• Suppression of electromagnetic interference on power cables
• Noise reduction on signal transmission lines
• Common mode choke applications for harnesses

Procurement Notes

Verify the cable diameter falls within the 0.514-inch inner dimension limit before procurement. Confirm that the application requires a hinged form factor rather than a split-core or slide-on type. Ensure the target frequency range aligns with the peak performance characteristics of Material 27 at 100 MHz. Check for any mechanical clearance constraints regarding the 1.142-inch width.

Selection Notes

Select this component when non-invasive installation on finished assemblies is required. The hinged design eliminates the need to thread cables through fixed cores. Choose Material 27 if the primary noise frequencies are addressed by its impedance profile. Compare physical dimensions against available space in the cable routing path. Consider the snap-on mechanism's retention strength for vibration environments.

Part Context

This ferrite core belongs to Laird-Signal Integrity Products' range of EMI suppression components. These cores are designed to attenuate high-frequency noise currents flowing on external conductors. The product line includes various materials and form factors to address diverse electromagnetic compatibility challenges in electronic systems.

Replacement Considerations

Direct substitutes must match the 260 Ohm impedance at 100 MHz and the 0.514-inch inner diameter. Alternative hinged cores using Material 27 should be evaluated for identical outer dimensions to ensure fit. Verify that any replacement maintains the same snap-on retention mechanism.
