The component operates within a frequency range of 25 MHz to 300 MHz and supports temperatures from -55°C to 125°C. Physical dimensions include an internal length of 26.67 mm, external length of 34.4 mm, external width of 12.7 mm, internal height of 1.91 mm, and external height of 6.35 mm.

Feature Summary

• Split design accommodates multi-conductor flat cables
• Utilizes 43-grade material for high-frequency applications
• Functions as a common-mode choke for EMI suppression

Applications

• High-frequency common-mode chokes
• Flat cable electromagnetic interference suppression
• Inductive applications requiring noise reduction

Procurement Notes

Verify the specific impedance value against official datasheets, as sources indicate variations between 34 ohms and 50 ohms at 100 MHz. Confirm that the physical dimensions match the required flat cable width. Ensure the 43-grade material specification aligns with the target frequency range of 25 MHz to 300 MHz for the intended application.

Selection Notes

Select this component when suppressing noise on flat ribbon cables in the VHF/UHF range. The split construction allows installation without disconnecting cables. The 43 material composition offers optimal performance for broadband noise attenuation. Verify compatibility with the specific cable thickness and width constraints defined by the internal and external dimensions.
