Product Description

We offer designs from 10 μH to 10 mH that maintain shape under ripple-heavy conditions at 20–500 kHz. With high-flux cores and tight winding layouts, our inductors limit EMI and preserve thermal headroom in compact spaces.

Transient Response Time

<10μs (For rapid load changes)

Frequency Range

DC-1MHz (Stable across operating spectrum)

DC Resistance (DCR)

0.001-0.1Ω (Minimizes conduction losses)

Core Material

High-flux powdered iron (Low core loss at high ΔB)

Tolerance (%)

±10% standard (±5% precision option)

Temperature Range

-40°C to +125°C (Full performance range)

Mounting Style

Through-hole or SMD (Vibration-resistant)

Termination Type

Heavy-duty pins or solder pads (Up to 200A)

Diode Compatibility

Schottky/SiC/GaN (Low Qrr for fast switching)

Certification Standards

AEC-Q200 Grade 1, UL Recognized, RoHS

Technical Advantages

Our filter inductors operate at switching frequencies up to 500 kHz without increased core temperature. Low DCR winding paths reduce conduction drop and support continuous ripple current up to 200 A.

We use thermally stable insulation and offer termination options for surface or through-hole mountings. Units are qualified to AEC-Q200 Grade 1 and meet RoHS and UL material standards.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate minimize high-frequency ripple in boost converter filter inductors?

Frigate engineers its filter inductors with tight inductance tolerances and low core loss materials. This helps suppress output ripple generated at high PWM switching speeds. Coil geometry and interwinding spacing are selected to reduce parasitic capacitance. These inductors are tested with typical ripple current profiles found in boost converter applications to validate suppression efficiency.

What makes Frigate’s filter inductors suitable for compact boost converter layouts?

Frigate uses high-flux core shapes that support high current density in small footprints. The coil winding layout is designed to optimize space while keeping thermal buildup low. These inductors integrate well into power-dense converter topologies, including vertical mount and planar module configurations. Mechanical stability is verified through shock and vibration tests.

How does Frigate address thermal stress in continuous operation at elevated ambient temperatures?

Frigate selects thermally stable core materials and Class H insulation for extended high-temperature endurance. The copper fill ratio is controlled to reduce resistive losses under full load. Heat rise is modeled across worst-case airflow conditions, and every inductor design is validated through temperature cycling. This ensures stable operation at 110°C panel temperatures without derating.

 

Can Frigate customize boost converter inductors for high ripple current handling?

Frigate offers filter inductors with optimized core gap and winding geometry for ripple-heavy duty cycles. Saturation testing is conducted under full ripple swing to ensure inductance retention. Custom designs include reinforced terminations and thermal shielding to manage prolonged stress. This makes them ideal for converters with steep voltage step-up requirements.

How does Frigate ensure EMI compatibility in high-frequency boost converter applications?

Frigate designs its inductors with controlled stray field emissions and uses core materials that dampen HF ringing. The winding layout minimizes loop area, reducing noise injection into nearby traces. Each inductor undergoes conducted and radiated EMI assessment across the 150 kHz–30 MHz band. Results confirm compliance with key industrial converter EMI thresholds.
