❓ Frequently Asked Questions
What is the primary function of the UU series common mode choke?
The UU-9.8 and UU-10.5 series are designed to suppress electromagnetic interference (EMI) and common mode noise in power supply circuits and electronic equipment.
What does the "Vertical" bobbin type imply?
A vertical bobbin means the component is designed for vertical mounting on a PCB, which helps save horizontal board space in compact electronic designs.
How do I choose between UU-9.8 and UU-10.5 series?
The choice depends on your specific inductance and rated current requirements. UU-10.5 generally offers different current handling capabilities compared to the UU-9.8 series.
What does "TBD" represent in the DC Resistance specification?
TBD stands for "To Be Determined." This indicates that the specific resistance value depends on the final winding configuration and can be confirmed upon request.
Are these chokes suitable for high-current applications?
These series support rated currents up to 2.0A. For applications exceeding this, please consult our technical team for specialized high-current components.
What is the minimum inductance available for these series?
The minimum inductance is 0.2 mH for the UU-9.8 series and 0.6 mH for the UU-10.5 series, as shown in the specifications table.
