Having Doubts? Our FAQ

Check all our Frequently Asked Question

What materials are used in Planar Transformers, and how do they impact performance?

Planar Transformers feature ferrite cores and copper foil windings integrated into PCB layers, designed for high-frequency efficiency. These materials ensure low core losses and tight magnetic coupling, delivering 92-99% efficiency and reliable power in compact systems. Their construction also reduces parasitic effects, enhancing stability for your high-speed manufacturing applications.

How does frequency range affect the performance of Planar Transformers in our production?

Planar Transformers operate from 50 kHz to 3 MHz, tailored for high-frequency power conversion in modern electronics. This broad range supports faster switching and smaller component sizes, improving your production efficiency and product compactness. Selecting the right frequency compatibility ensures optimal performance without excess energy waste in your designs.

What role does compact design play in the effectiveness of Planar Transformers?

The slim profile of Planar Transformers, starting at 5 mm high, allows seamless integration into space-limited assemblies. This compactness reduces system bulk and simplifies your manufacturing process, ensuring consistent power delivery without compromising design flexibility. It also helps meet tight production deadlines by streamlining assembly in dense layouts.

Why is environmental resistance important for Planar Transformers in our facilities?

Planar Transformers withstand humidity up to 95% RH and temperature swings from -40°C to 150°C, critical for tough manufacturing environments. Their robust resistance prevents performance degradation, ensuring reliable operation and fewer replacements in your production lines. This durability supports uninterrupted workflows, even under demanding conditions.

What safety features should we prioritize in Planar Transformers for our equipment?

Look for Planar Transformers with optional overcurrent protection and thermal shutdown features to enhance operational safety. These safeguards cut power during faults, reducing risks of overheating or electrical issues in your high-frequency systems. Compliance with standards like IEC 61558-2-6 also ensures they meet rigorous safety requirements for your manufacturing needs.
