CW28B1937

Overview

The CW28B1937 is a hinged ferrite core manufactured by Leader Tech Inc., designed for electromagnetic interference suppression on cables. Constructed from material grade 28, this component provides an impedance of 117 ohms at 100 MHz. It features a round shape with a hinged clamp design for easy installation around existing wiring. The internal diameter measures 10.21 mm, while the external dimensions are approximately 28.60 mm in diameter and 14.00 mm in length. The unit is supplied in bulk packaging.

Feature Summary

• Hinged clamp design allows for installation around pre-existing cables without disconnection
• Utilizes grade 28 ferrite material for effective high-frequency noise attenuation
• Round cross-section geometry accommodates standard cylindrical cable profiles

Applications

• Suppression of electromagnetic interference on communication cables
• Noise reduction on power supply lines in electronic enclosures
• EMI filtering for interconnect cables in circuit board assemblies

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before integration. Confirm that the hinged mechanism meets the mechanical retention requirements of the target assembly. Ensure compatibility with the cable outer diameter range specified by the manufacturer to maintain optimal magnetic coupling and shielding effectiveness.

Selection Notes

Select this component when a non-invasive installation method is required for cable-mounted ferrites. The hinged design offers convenience over snap-fit or split-core variants that may require cable removal. Consider the 117-ohm impedance profile at 100 MHz to ensure it aligns with the frequency spectrum of the noise sources present in the application environment.

Part Context

Leader Tech Inc. specializes in EMI shielding solutions for circuit boards and interconnect cables. This ferrite core belongs to their line of cable-mounted suppressors, which are engineered to mitigate conducted emissions. The product supports compliance with electromagnetic compatibility standards by attenuating high-frequency noise on signal and power lines within electronic systems.

Replacement Considerations

Cross-reference part numbers such as TC28B0937 or CF28B1937 for similar ferrite cores. Verify that substitute components match the critical parameters of 117 ohms impedance at 100 MHz and compatible internal diameter dimensions to ensure equivalent performance in the final assembly.
