High-performance EMC common-mode inductor core (SYG2)

Performance characteristics

Outstanding high-frequency characteristics (µ(100 kHz) ≥ 30,000)
Flexible frequency characteristics: Different frequency response curves can be obtained by adjusting various levels of permeability.
Wider permeability adjustment range: The permeability µ (10 kHz) can be flexibly adjusted by modifying the production process (15,000–120,000).
Excellent temperature stability
Low loss, high Bs
An epoxy surface coating can be used to more effectively reduce the size of the magnetic core.

Scope of application

Switching power supply
UPS uninterruptible power supply
Common-mode filters for single-phase or three-phase power lines and various power sources
