Frequently Asked Questions
What is the main advantage of a wire wound common mode filter over other types?
The wire wound construction typically allows for higher common mode impedance and better high-frequency performance compared to multilayer chip types, making it more effective for suppressing EMI in critical signal integrity applications.
How do I interpret the impedance rating of 800Ω @100MHz?
This means the filter presents an impedance of 800Ω (typical) to common-mode noise currents at a frequency of 100MHz. A higher impedance at the noise frequency results in greater attenuation of that noise.
Can this filter handle higher currents for power line applications?
The rated current is 0.15A Max. It is designed for low-current signal or power lines. For higher current power rail filtering, please select a model with a correspondingly higher current rating.
What does "halogen-free" mean and why is it important?
Halogen-free means the product does not contain chlorine, bromine, or other halogens above certain thresholds. This is important for environmental safety and is often required in green electronics initiatives, as it reduces the emission of toxic gases in case of fire.
