High Current Inductor
Single Winding, HC1
SMD Device
Description:
• 125°C Maximum total operating temperature
• Designed for high current, low voltage applications
• Low DCR, high efficiency
• Foil construction for higher frequency circuit designs
• Suited for IR and vapor reflow solder
• Frequency range 1kHz to 1MHz
• Ferrite core material
Dimensions - mm
