SE25B0121

Overview

The SE25B0121 is a clamp-on ferrite core manufactured by Leader Tech Inc., designed for electromagnetic interference (EMI) suppression. It features a split-core design that allows installation around existing cables without disconnecting them. The component provides an impedance of 245 Ohms at 700 MHz. Its physical dimensions are specified as 25.70 mm in width and 1.50 mm in height, with an inner diameter accommodating cable sizes up to 1.012 inches wide. The outer dimensions measure 33.40 mm in width and 0.406 inches in height.

Feature Summary

• Split-core construction enables non-invasive attachment to existing wiring harnesses
• Provides high-frequency noise attenuation through magnetic material properties
• Free-hanging form factor suitable for flexible cable routing

Applications

• Suppression of common-mode noise on flat ribbon cables
• EMI filtering in computer peripheral connections
• Noise reduction in internal bus cabling within electronic enclosures

Procurement Notes

Verify the specific impedance value and frequency rating against the official datasheet before integration. Confirm that the cable cross-section fits within the specified inner diameter limits. Ensure the product meets required environmental standards for the intended deployment environment.

Selection Notes

Choose this component when non-destructive installation on pre-assembled cables is required. The split design avoids rewiring efforts. Verify that the target cable width does not exceed the maximum inner dimension to ensure proper magnetic coupling and effective noise suppression performance.
