1. Integrates the functions of three choke coils in compact size (reducing mounting space by 1/3):
(1) General-purpose common mode choke coil (for mains terminal interference voltage)
(2) General-purpose differential mode choke coil (for differential mode noise)
(3) Common mode choke coil for high-frequency noise (radiation noise)
2. Low Profile (H=<13mm)
1. Noise suppression circuits in AC power supplies and AC adapters
2. Noise suppression circuits required to handle not only mains terminal interference voltage, but also radiation noise in the FM band.
3. Low-profile versions of equipment such as lighting systems, flat panel displays, and audio products, especially digital amplifiers
