Fixed inductors are components designed to introduce inductance into a circuit. The CDR10D48MNNP-470NC (also referred to as the ‘CDR’ hereafter) is no exception. It is an SMD (Surface Mount Device), power inductor that is commonly used for a range of power supply applications, including power-hungry chipsets such as the Intel® Core (TM) i7 processor.

The CDR offers a maximum operating temperature of up to 125°C, which is well above the operating temperatures of most components. This makes it particularly suitable for more thermally demanding environments, such as in automotive applications. It also offers a maximum current of up to 47.0A, making it a powerful inductor for its size.

The CDR is constructed from an advanced nanocrystalline magnetic material, which allows for a high amount of current to be transferred across the inductor while still providing superior thermal and mechanical performance. The body of the component is an anodized copper shell, which not only provides a high degree of mechanical robustness, but also allows for efficient heat dissipation.

The CDR is available in two different versions: a through-hole version, and a surface-mount version. In either case, the inductor features a 4-pin design, with two pins serving as the power supply input, and two pins serving as the power output. The construction of the pins allows for a full electrical contact between the pins and the PCB (Printed Circuit Board), providing improved power efficiency.

On the working principle side of things, the CDR operates using standard inductor operation. Inductors are passive devices that oppose any changes in current flow, meaning current flowing through them takes time to increase or decrease. By doing this, the inductor stores energy in the form of a magnetic field, which is then released back to the circuit when the current flow is reversed, providing a more stable power supply with low noise.

The CDR is typically used to supply power to critical components such as control ICs. In this application, it helps to ensure that the component receives a stable voltage, as the inductor helps to regulate any voltage instabilities that may be present in the power grid. The CDR is also used to keep power levels stable when the engine is running, helping to reduce the risk of damaging components due to power fluctuations.

The CDR is also commonly used in automotive electronics, where it can help to reduce interference caused by power fluctuations from the battery or alternator. This helps to improve the performance and reliability of the vehicle’s electronics, and improve the safety of its passengers.

All in all, the CDR10D48MNNP-470NC is a powerful and versatile fixed inductor that can be used in a variety of applications. Its high current rating and robust construction make it well-suited for demanding environments, while its high operating temperature rating makes it a great choice for automotive applications. With its 4-pin design, it can provide reliable power delivery and regulation, making it an ideal choice for power supply applications.
