Product Description
Product Overview
This series of surface-mount inductors offers a compact and ultra-thin design with high power handling capabilities, high saturation, and low resistance. Featuring a magnetic-resin shielded structure, these inductors significantly reduce buzz noise and magnetic leakage, providing strong anti-EMI performance. They offer a rated current over 30% higher than traditional inductors of the same size and operate across a wide frequency range up to 5MHz. These products are RoHS and halogen-free compliant, making them an environmentally conscious choice for various electronic applications.
