35U1260-320

Overview

The 35U1260-320 is a cable ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 42 Ohms at 5 MHz. The component features an inner diameter of 0.717 inches (18.20 mm) and an outer diameter of 1.260 inches (32.00 mm). Its physical dimensions are 0.157 inches in height (4.00 mm) and 0.315 inches in height (8.00 mm). This passive electromagnetic interference filter is designed for surface mounting on cables to suppress noise.

Feature Summary

• Provides 42 Ohms impedance at 5 MHz for effective noise suppression
• Designed for direct application on cables as a ferrite core
• Constructed with specific inner and outer diameters for secure cable fitment

Applications

• Cable noise filtering
• Electromagnetic interference suppression
• Signal integrity enhancement on wiring harnesses

Procurement Notes

Verify the exact dimensional requirements against the target cable diameter before procurement. Confirm that the 42 Ohm impedance at 5 MHz aligns with the specific frequency spectrum of the interference being mitigated. Ensure the physical form factor matches the available space in the assembly. Check for any specific environmental ratings if the deployment involves extreme temperatures or harsh conditions.

Selection Notes

Select this component when a high-impedance ferrite solution is required specifically at the 5 MHz frequency range. The choice depends heavily on matching the cable's outer diameter to the core's inner diameter of 0.717 inches. Consider the physical size constraints, as the core has a substantial footprint compared to smaller chip beads. Evaluate whether the fixed impedance characteristic meets the system's EMI reduction targets without affecting signal integrity.

Part Context

This part belongs to the cable ferrite category within Laird-Signal Integrity Products' portfolio. Unlike surface-mount chip beads, these cores are intended for wrapping around existing cables. They serve as a straightforward method for adding bulk attenuation to noisy lines without requiring PCB layout changes. The product line focuses on providing robust shielding solutions for various industrial and commercial applications.

Replacement Considerations

Direct substitutes must match the 42 Ohm @ 5 MHz specification and the 0.717-inch inner diameter. Alternative brands may offer similar impedance profiles but require verification of physical dimensions to ensure compatibility with the existing cable assembly.
