Frequently Asked Questions (FAQ)
Q What core shapes and sizes are available for these DR inductors?
We offer a wide range of standard core shapes including DR4*6, DR6*8, DR8*10, DR9*12, DR10*12, DR14*15, and various DR RFB configurations. Custom sizes can also be accommodated.
Q Can I request custom Inductance and DC Resistance (DCR)?
Yes, custom designs for both Inductance and maximum DC Resistance are fully supported to meet your specific circuit requirements.
Q What material is used for the magnetic core?
The standard design utilizes high-performance PC40 series ferrite cores, optimized for low loss and high efficiency.
Q What switching frequency are these specifications based on?
The standard electronic specifications are designed and tested based on a switching frequency of 100KHz using a forward model.
Q Are the lead wire diameters (CD) standard across all sizes?
No, the lead wire diameter (CD) varies from 0.5mm to 1.0mm depending on the core shape and maximum current requirements to ensure optimal performance.
