The STRF016 series high-current SMD common-mode choke inductor is designed for DC-DC and AC-DC converter applications. The product uses a magnetic shield structure to effectively reduce EMI. It provides high common-mode impedance across a wide frequency range, delivering excellent EMI suppression performance. Multiple sizes and current ratings are available. Tape and reel packaging supports SMT automated placement and is compatible with reflow soldering. The operating temperature range is -40°C to +125°C (including self-temperature rise), suitable for various harsh environments. It is widely used in DC-DC/AC-DC converters, communication systems, automotive electronics, and LCD TVs.
A: The magnetic shield structure uses a closed magnetic circuit design to confine magnetic flux inside the core. It effectively reduces leakage flux and electromagnetic interference to nearby sensitive circuits. In high-density PCB layouts such as communication equipment and automotive electronics, shielded inductors significantly improve system EMC performance.
A: The STRF016 series provides high common-mode impedance across a wide frequency range, effectively attenuating common-mode noise current. Combined with the magnetic shield structure, the overall EMI performance is excellent. It is especially suitable for DC-DC and AC-DC power designs with strict EMI requirements.
A: IDC is defined as the DC current value that causes a temperature rise of approximately 40°C in the coil. In actual applications, ensure that the maximum operating ambient temperature plus self-temperature rise does not exceed 125°C. When selecting, allow sufficient margin to ensure long-term reliability.
A: It supports both vapour phase soldering and infrared reflow soldering SMT processes. Soldering heat resistance is 260°C for 10 seconds, compatible with lead-free reflow temperature profiles. Tape and reel packaging is suitable for automated placement lines.
