AS25B2030

Overview

The AS25B2030 is a hinged ferrite core manufactured by Leader Tech Inc., designed for electromagnetic interference (EMI) suppression on cables. It features a square shape with an inside diameter of 6.9 mm and an outside length of 32.1 mm. The component has an outside width of 20.1 mm and an outside height of 19.6 mm. It provides an impedance of 390 Ohms at 700 MHz. The unit weighs approximately 0.8 oz and is packaged in bulk quantities.

Feature Summary

• Hinged box sleeve snap design allows for easy installation onto existing cables without disconnection.
• Square cross-section geometry supports both round and flat cable configurations.
• Frequency-specific ferrite formulation targets EMI noise reduction in the high-frequency range.

Applications

• Suppression of electromagnetic interference on single cables within electronic assemblies.
• Noise filtering for data and power lines in communication equipment.
• EMI shielding for wires in industrial control systems.

Procurement Notes

Verify the specific impedance curve and frequency response characteristics against your application requirements using the official Leader Tech datasheet. Confirm that the 6.9 mm internal diameter accommodates the target cable bundle size with appropriate clearance. Ensure compliance with RoHS directives if required by your manufacturing standards. Check for any specific handling instructions regarding the hinge mechanism to prevent damage during installation.

Selection Notes

Select this part when a reusable, clamp-on solution is preferred over split-bead or solid-core alternatives. The 390 Ohm impedance at 700 MHz makes it suitable for higher frequency noise suppression compared to lower-impedance variants. Consider the physical dimensions to ensure adequate space around the cable path. Compare with similar models like SS25B2030 if adhesive mounting is not required, noting that the hinged design offers distinct installation advantages.

Part Context

This component belongs to the Leader Tech FerriShield line of ferrite cores, which are widely used for EMI shielding. The 'AS' prefix typically denotes a hinged or bisected style, allowing for post-assembly installation. These components are passive elements used to absorb high-frequency noise energy, converting it into heat, thereby reducing radiated emissions from cables.

Replacement Considerations

The SS25B2030 is a non-hinged variant with identical external dimensions and likely similar electrical properties, serving as a functional substitute if installation occurs before cable termination. Verify impedance curves match exactly, as material formulations can vary between specific suffixes even within the same dimensional family.
