Compact inductors for demanding circuits

Max Echo Technology is a renowned manufacturer of electronic components, founded in 1992 in Taichung, Taiwan. For over three decades, the company has continuously developed its expertise in the design and production of magnetic components, providing solutions that meet the demanding requirements of modern electronics. The production facility, located in the Taichung Precision Science Park, serves as a center for research and development, where innovative technologies in magnetic and ceramic materials are created, along with advanced multilayer printing and low-temperature co-firing processes.

As a distributor of Max Echo products, we offer a wide range of SMD inductors that combine precise manufacturing with excellent electrical performance. Max Echo SMD inductors are compact magnetic components designed for effective suppression of electromagnetic interference (EMI) and for shaping the frequency response of electronic circuits. Thanks to rigorous testing and the use of high-quality materials, they ensure stable operation over a wide temperature range, making them suitable for use in industrial, telecommunication, and power systems. Their design combines low power loss (low DCR) with predictable electrical characteristics, which is crucial in the design of power supplies, input filters, and signal paths.

Key Features

• Compact SMD sizes (0402, 0603, 0805) – save PCB space and fully compatible with surface-mount technology.
• Low DCR relative to inductance and rated current – minimizes power loss, essential in power supply circuits and filters.
• Wide range of inductance values and tolerances – from low nH for RF filters to hundreds of nH for low-pass filters and power circuits.
• Temperature stability – operating up to 125 °C (some models limited to 85 °C), ensuring reliable performance in demanding environments.
• Good RF performance – predictable inductance and impedance in specified frequency ranges, facilitating the design of filter circuits and signal paths.

Note: rated currents, DCR, and inductance values vary by model and should be considered when selecting components.

Applications

• RF input filters — 4.7 nH / 5.6 nH for impedance matching and interference suppression in radio frequency bands.
• EMI suppression / power filters — 15–220 nH for signal isolation and suppression of conducted disturbances.
• Analog and audio circuits — low-DCR inductors minimize losses while maintaining effective interference suppression.
• HF circuits and converters — lower nH values for resonant circuits and impedance matching.
• Measurement equipment and portable devices — ideal for applications requiring compact design, low weight, and minimal PCB footprint
