Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure stable inductance in air core inductors at high frequencies?

Frigate uses precision-wound coils with optimized pitch and spacing to reduce parasitic capacitance and maintain stable inductance. The absence of magnetic core eliminates hysteresis and saturation issues. Each unit is tested across a wide frequency spectrum to verify consistent performance in RF and high-speed digital systems. 

What makes Frigate’s air core inductors suitable for high-power RF applications?

Frigate designs these inductors with thick-gauge conductors and controlled spacing to handle high current without thermal drift. The open construction supports efficient heat dissipation and limits skin effect at elevated frequencies. Frigate validates performance using vector network analysis to confirm Q-factor and current handling capacity. 

 

How does Frigate minimize electromagnetic coupling in dense PCB layouts using air core inductors?

Frigate applies vertical coil geometries and low-profile designs to reduce magnetic field interference with nearby components. Shielding techniques and layout guidance are provided when needed. Each inductor is tested for coupling behavior under representative board densities to ensure compatibility with compact system architectures. 

Are Frigate’s air core inductors effective in pulse circuits requiring fast response times?

Frigate’s air core inductors exhibit minimal energy storage delay due to their non-saturating structure and low inductive time constants. The winding geometry reduces transient voltage spikes. Frigate evaluates response times under pulsed signal conditions to confirm fast magnetic behavior and waveform stability. 

What steps does Frigate take to ensure mechanical durability in air core inductor designs?

Frigate secures the windings using resin coatings and structural supports to prevent vibration-induced wire fatigue. Spacer materials resist thermal deformation during operation. All designs undergo vibration and thermal cycling tests to validate mechanical integrity for automotive, aerospace, and telecom-grade environments.
