KEMET SBC Series Ferrite Power Inductor 220µH 1.1A

The KEMET SBC Series Ferrite Power Inductor is a robust, drum-core component designed for demanding power conversion applications. With an inductance of 220µH, it is engineered to provide stable energy storage and filtering, making it a key component in modern electronic circuits.

Constructed with a high-performance nickel-zinc (NiZn) ferrite core, this unshielded inductor offers excellent magnetic properties for efficient operation. It is rated for a maximum RMS current of 1.1A and a saturation current of 2.3A, ensuring reliable performance under significant load conditions. Its low DC resistance of a maximum 0.33ohm helps to minimise power loss and heat generation.

This component is built to endure, with an operating temperature range extending up to +105°C, making it suitable for use in environments where heat management is critical. The compact dimensions allow for efficient use of board space in densely packed designs.

Applications

Ferrite power inductors like this are versatile and essential for smoothing current and filtering noise in a wide range of power supply circuits. Typical uses include:

• DC/DC converters for efficient voltage step-down or step-up.
• Noise filters in power lines to ensure clean, stable power delivery.
• LED lighting drivers and control systems.
• Telecommunications equipment such as xDSL modems.
• Office equipment including photocopiers.
• Consumer electronics like flat-screen televisions.
• Smart meter power management circuits.
• General-purpose switched-mode power supplies (SMPS).
