KEMET SBC Series Ferrite Power Inductor, 3.3mH, Unshielded

The KEMET SBC Series Ferrite Power Inductor is a high-performance component engineered for demanding power management applications. With an inductance of 3.3 millihenries (mH), this unshielded inductor is built on a robust drum core construction using a nickel-zinc (NiZn) ferrite core, offering excellent magnetic properties and thermal stability. Its magnetic non-shield type design makes it a versatile and cost-effective choice for a wide range of circuit layouts.

Key to its reliable operation is its ability to handle significant current loads, with an RMS current (Irms) rating of 360mA and a saturation current (Isat) of 630mA. This ensures stable performance in switching circuits without core saturation. The inductor features a low maximum DC resistance of 3.51 ohms, which helps to minimise power loss and heat generation during operation.

Designed for durability, it operates within a temperature range of up to +105°C, making it suitable for environments where consistent performance under thermal stress is required. Its compact dimensions allow for efficient use of board space in modern electronic designs.

Typical Applications

This ferrite power inductor is a fundamental component in power conversion and noise filtration circuits. Its primary uses include:

• DC/DC converters for efficient voltage step-up or step-down.
• Noise filters in power supply lines to suppress electromagnetic interference (EMI).
• LED lighting drivers and power systems.
• Telecommunications equipment such as xDSL modems.
• Office machinery including copying machines.
• Consumer electronics like flat-screen televisions.
• Smart metering and monitoring systems.
• General-purpose switched-mode power supplies (SMPS).
