SMD Coupled Inductor

Our SMD Coupled Inductors are engineered to meet the demanding requirements of modern power electronics, where compact size, high efficiency, and excellent EMI suppression are critical. By integrating two magnetically coupled windings into a single surface-mount package, these inductors provide superior current ripple cancellation and enhanced energy transfer efficiency.

Compared with traditional discrete inductors, a high current coupled inductor enables optimized power density while reducing component count and PCB area, making it ideal for space-constrained designs.

Key Features of Coupled Inductor SMD

• High Current Capability
  Designed to handle large DC currents with minimal saturation, suitable for power conversion and load regulation circuits.

• Enhanced EMI Performance
  Magnetic coupling helps suppress differential-mode noise, improving system EMC compliance. This makes the device a strong complement to EMI solutions such as a Power Line Common Mode Choke.

• Compact SMD Construction
  Fully compatible with automated reflow soldering processes, aligning well with modern SMD Inductor assembly requirements.

• Stable Inductance Over Temperature
  Ferrite Core materials ensure consistent electrical performance across a wide operating temperature range.

• Low DC Resistance (DCR)
  Reduced copper loss supports higher efficiency in high-current designs.

SMD ferrite bead inductor vs. Coupled Inductor

While a smd ferrite bead Inductor is primarily used for high-frequency noise suppression, a coupled inductor serves both energy storage and ripple reduction functions. This dual capability allows designers to simplify power stage layouts and improve overall efficiency in DC-DC converters.

Typical Applications

• DC-DC buck and boost converters

• Multiphase power supplies

• Automotive and industrial power modules

• POL (Point-of-Load) regulators

• High-current filtering stages in power distribution networks
