HFA187102-0A2

Overview

The HFA187102-0A2 is a hinged snap-on ferrite core designed for free-hanging cable applications. It provides high-frequency EMI suppression with an impedance of 220 Ohms at 300 MHz. The component features a circular inner diameter of 10.00 mm (0.394 inches) to accommodate round cables. Its physical dimensions include an outer diameter width of 22.88 mm, height of 21.84 mm, and total length of 32.77 mm. This split-core design allows for installation on existing wiring without disconnection.

Feature Summary

• Hinged snap-on mechanism enables easy installation on pre-existing cables
• Provides effective common and differential mode EMI suppression
• Free-hanging design suitable for round wire and cable applications

Applications

• High frequency EMI suppression on round cables
• Common mode noise filtering in wiring harnesses
• Differential mode noise reduction on existing circuits

Procurement Notes

Verify the inner diameter requirement matches the target cable size of 10.00 mm before procurement. Confirm that the hinged snap-on style is compatible with the assembly process. Ensure the application environment does not exceed the material temperature limits specified in the official datasheet. Check for RoHS compliance status if required by specific regional regulations.

Selection Notes

Select this component when non-invasive installation on existing cables is required. The 10 mm inner diameter dictates the maximum cable thickness it can accommodate. Consider the 220 Ohm impedance at 300 MHz for matching the target noise frequency spectrum. Evaluate the physical footprint constraints against the 32.77 mm length and 22.88 mm width dimensions.

Part Context

This part belongs to Laird-Signal Integrity Products' ferrite core lineup, specifically engineered for signal integrity and electromagnetic interference mitigation. Unlike chip beads or through-hole cores, this snap-on type serves as a retrofit solution for cable management systems where cutting wires is impractical or prohibited.

Replacement Considerations

HI1206T500R-10 is listed as a direct substitute for other Laird components but is a surface mount bead, not a ferrite core. No verified direct replacement part number is available for the HFA187102-0A2 in the provided documentation. Any substitution must match the 10 mm ID and snap-on mechanical form factor.
