KEMET Ferrite Power Inductor, 1.2µH, 7.5A RMS

The KEMET SBC Series Ferrite Power Inductor is a high-performance component essential for modern electronic power management. Featuring a drum core construction with a nickel-zinc (NiZn) ferrite core, it is designed for efficiency and reliability in demanding circuits. This unshielded (magnetic non-shield type) inductor offers stable performance across a wide operating temperature range of up to +105°C, making it suitable for various industrial and consumer applications.

Engineered for power integrity, this inductor boasts a low DC resistance (maximum 0.01Ω), which minimises power loss and heat generation. Its key specifications include an inductance of 1.2µH with a tolerance of ±20%, an RMS current (Irms) rating of 7.5A, and a saturation current (Isat) of 9.8A, ensuring robust operation under load.

Typical Applications

This versatile component is a fundamental building block in power supply design. Its primary uses include:

• Integration into DC/DC converters for voltage step-down or step-up regulation.
• Serving as an effective noise filter to suppress electromagnetic interference (EMI) and ensure clean power delivery.
• Implementation in LED lighting drivers for stable current control.
• Use in telecommunications equipment such as xDSL modems.
• Incorporation into office machinery like copying machines.
• Application in consumer electronics including flat-screen televisions.
• Utilisation in smart grid technology for smart meters.
• General-purpose switch-mode power supplies (SMPS).

With its compact physical dimensions and proven ferrite core technology, the KEMET inductor provides a reliable and efficient solution for engineers designing compact, high-performance power circuits.
