28A1507-0A2

Overview

The 28A1507-0A2 is a split snap-on ferrite core manufactured by Laird-Signal Integrity Products. It provides EMI suppression for round cables with a maximum inner diameter of 0.276 inches (7.00 mm). The component exhibits an impedance of 123 Ohms at 100 MHz and utilizes material grade 28. Its physical dimensions include an outer diameter of 0.591 inches (15.00 mm) and a length of 0.709 inches (18.00 mm). Designed for free-hanging installation, it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Split hinged design allows for easy installation on existing cables without disconnection
• Provides broadband common and differential mode EMI suppression
• Constructed from material grade 28 for effective noise attenuation

Applications

• Suppression of electromagnetic interference on round cables
• Broadband noise filtering in signal integrity applications
• Post-production cable assembly modification

Procurement Notes

Verify the specific supplier documentation to confirm RoHS3 compliance status and REACH regulatory standing before integration. Ensure the target cable diameter does not exceed the 7.00 mm internal dimension to guarantee proper mechanical fit and magnetic circuit closure. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and current production status.

Selection Notes

Select this component when retrofitting EMI protection onto assembled cables is required. The split design eliminates the need to thread cables through solid cores. Confirm that the operating frequency range aligns with the 123 Ohm impedance characteristic at 100 MHz. Verify that the ambient temperature conditions remain within the specified -40°C to +125°C operational limits for reliable performance.

Part Context

This component belongs to the 28A series of cable ferrites from Laird-Signal Integrity Products. It serves as a modular alternative to solid ferrite cores, facilitating maintenance and assembly flexibility. The product line focuses on providing standardized EMI solutions for various cable diameters using consistent material properties across the series.

Replacement Considerations

Solid ferrite cores such as the 28B0157-100 offer similar material characteristics but require pre-assembly cable threading. Other split cores like the 28A2029-0A2 provide higher impedance values but accommodate larger cable diameters. Evaluate mechanical constraints and required attenuation levels when considering these alternatives.
