Frequently Asked Questions
What are the primary applications for the UU-9.8 and UU-10.5 series chokes?
These common mode chokes are primarily used for noise suppression in switching power supplies, adapters, and various electronic devices to ensure electromagnetic compatibility (EMC).
What is the difference between the UU-9.8 and UU-10.5 core shapes?
The main difference lies in their physical dimensions and power handling capabilities. The UU-10.5 series generally offers a slightly larger footprint allowing for different inductance and current rating combinations compared to the UU-9.8.
Can these common mode chokes be customized for specific inductance values?
Yes, while the standard table shows common values from 0.2mH to 70mH, custom windings can be manufactured to meet specific electronic specifications.
What does "TBD" mean in the DC Resistance column?
"TBD" stands for "To Be Determined." It indicates that the specific resistance value depends on the final wire gauge and winding density used for that high-inductance configuration.
Are these chokes suitable for high-current applications?
The rated current for these series ranges from 0.1A up to 2.0A. For applications requiring higher than 2.0A, a larger core size or different series may be recommended.
What is the benefit of the vertical bobbin type?
The vertical bobbin design helps save valuable PCB real estate (footprint), making it ideal for compact power supply designs and high-density electronic assemblies.
