35T0870-00H

Overview

The 35T0870-00H is a ferrite toroid core manufactured by Laird-Signal Integrity Products, belonging to the 35T series. It features an MnZn material composition suitable for electromagnetic interference suppression. The component has an outer diameter of 22.10 mm, an inner diameter of 13.72 mm, and a height of 6.35 mm. It is supplied in bulk packaging with a standard factory quantity of 720 units.

Feature Summary

• Utilizes MnZn ferrite material for effective high-frequency noise attenuation
• Toroidal geometry provides efficient magnetic flux containment
• Designed for through-hole winding applications on circuit boards

Applications

• Common mode choke cores for power supply lines
• EMI suppression in telecommunications equipment
• Filtering components in industrial control systems

Procurement Notes

Verify the specific MnZn material grade and impedance characteristics against the official Laird datasheet before integration. Confirm that the bulk packaging format aligns with your winding automation requirements. Ensure the physical dimensions match your mechanical constraints for the final assembly.

Selection Notes

Select this component when a toroidal shape is required for superior magnetic shielding compared to bead types. Consider the current carrying capacity of the wound wire rather than the core itself. Evaluate the operating frequency range to ensure the MnZn material properties provide adequate attenuation at the target noise frequencies.

Part Context

This part belongs to the Laird 35T series of ferrite cores, which are widely used for discrete inductor and transformer construction. The series offers various sizes to accommodate different winding counts and current levels. These cores are distinct from surface mount ferrite beads, offering higher flexibility for custom inductance values.

Replacement Considerations

Direct substitutes include other Laird 35T series toroids with identical dimensions but potentially different material grades. Cross-brand replacements require matching the outer diameter, inner diameter, and height precisely to fit existing tooling and fixtures.
