Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate optimize auxiliary inductors for high-frequency switching converters?

Frigate uses low-loss ferrite cores and compact multilayer winding designs to support frequencies above 100 kHz. This minimizes core losses and skin effect-related heating. The inductance remains stable across thermal and load variations. Each unit undergoes sweep-frequency response testing to verify consistent behavior under rapid switching conditions. 

What makes Frigate’s auxiliary inductors suitable for power supply isolation tasks?

Frigate designs auxiliary inductors with tight magnetic coupling and controlled leakage paths. This supports efficient energy transfer between primary and secondary circuits while maintaining isolation. Insulation systems follow IEC 61558 standards. Units are high-pot tested to ensure safety in control and gate-drive applications. 

How does Frigate address space constraints in control board layouts using auxiliary inductors?

Frigate engineers compact auxiliary inductors using toroidal and bobbin-based cores with low-profile winding geometries. The winding fill factor is maximized without compromising thermal margin. Products are available in multiple footprint configurations to fit dense PCBs. Thermal rise is limited using optimized copper usage and verified with airflow simulations. 

Can Frigate’s auxiliary inductors handle dual-function roles such as energy storage and filtering?

Frigate designs auxiliary inductors with stable inductance curves and low AC resistance across the operational range. This enables dual use as energy storage and EMI-filtering components. Magnetic materials are selected for minimal distortion under ripple current. Designs undergo combined load and noise rejection tests before release. 

What thermal design practices does Frigate follow for auxiliary inductor reliability?

Frigate selects thermal class H or N insulation based on application demands. Core materials have low eddy and hysteresis loss. The design limits hot spot formation through balanced winding distribution and verified heat sinking interface. Each part is endurance-tested at elevated ambient conditions to confirm thermal reliability without derating.
