UU 9.8 Vertical
INF
They meet the UL 94 V-0 flammability standard and climatic category 40/125/21, with an ambient temperature limit of 50℃, dielectric strength of >1500 V between windings, and stable electrical performance at 25℃.
Ultra-high common mode noise suppression up to 70dB, providing excellent anti-interference protection for small electronic systems
Extremely low stray inductance ratio, delivering precise and balanced attenuation for symmetrical interference signals
High-strength electrical isolation between windings, enhancing circuit safety and anti-breakdown performance
