FAQ
Q: What is the inductance range of the STR0602 series?
A: The STR0602 series covers an inductance range from 10µH to 300µH, covering a wide range of applications from small inductance values to medium inductance values. Lower inductance values are suitable for high-frequency filtering applications, while higher inductance values are suitable for low-frequency common-mode interference suppression.
Q: What are the advantages of single-layer winding?
A: Single-layer winding eliminates inter-layer parasitic capacitance. It provides higher common-mode impedance and more stable filtering performance across a wide frequency range. The single-layer structure also offers better heat dissipation and more consistent winding, making it suitable for power designs with strict EMI suppression requirements.
