| High Light | toroidal common mode choke ，high frequency common mode choke ，AC DC noise suppression choke | ||
The TRF series high-frequency toroidal common-mode choke uses a toroidal core and dual-winding design. Rated current covers 1.5A to 18A. Inductance ranges from 1mH to 120mH. Common-mode resonance frequency ranges from 100KHz to 3MHz. The product offers excellent mechanical strength, low DCR, and low temperature rise. It effectively eliminates electromagnetic noise in power and signal circuits. Multiple PCB mounting housings are available to suit different layout requirements. Operating temperature range: -40°C to +105°C. It is widely used in AC/DC and DC/DC line noise suppression, communication systems, automotive electronics, LCD/PDP TVs, and computer peripherals.
Q: What EMI standards does this product comply with?
A: The TRF series common-mode chokes comply with international EMI standards including FCC, VCCI, CISPR, and FTZ. They help your products pass conducted emission compliance tests and reduce electromagnetic interference on power and signal lines.
Q: What is the significance of the 100KHz-3MHz common-mode resonance frequency?
A: Common-mode chokes provide the highest common-mode impedance near the resonance frequency, achieving optimal noise suppression. The 100KHz-3MHz resonance frequency range covers the main conducted EMI frequency bands of switching power supplies and digital circuits, ensuring effective common-mode noise attenuation in critical frequency ranges.
Q: How does the +50%/-30% inductance tolerance affect selection?
A: This tolerance range means the actual inductance may be up to 50% higher or 30% lower than the nominal value. In EMI filtering applications, when selecting, ensure the inductance meets the minimum filtering requirements across the full temperature and operating current range. We recommend allowing sufficient margin in critical designs.
