Fixed Inductors are an essential component of most electronic circuit designs. As the name suggests, the inductor is designed to hold a constant or variable amount of inductance over a predetermined frequency range. The CDRH10D48/ANP-8R7MC is a high-performance chip-sized tantalum surface-mount type of fixed inductor. It is a multi-layer ceramic core component, which has an excellent high frequency performance up to 12GHz with a minimum inductance of 47nH. This article aims to briefly describe the application field and working principle of the CDRH10D48/ANP-8R7MC.

Fixed inductors are useful for applications requiring a constant inductance over a wide frequency range. As the name implies, they are used to maintain the inductance of a circuit at a certain level or frequency without changes due to environmental conditions. Some of the most common applications of fixed inductors range from impedance matching of power supplies, filtering of high/low frequency signals, elimination of harmonics, and stability of voltage/current along a specific frequency range.

The CDRH10D48/ANP-8R7MC series fixed inductors are particularly suitable for RF applications. They offer a high Q-factor up to 33 at 1GHz, and a high self-resonance frequency of up to 12GHz. This makes them well suited for high-frequency tuning, impedance matching, and power supply filtering applications. The inductor also features an extremely low DCR of 0.2Ω, which ensures minimal power loss and improved signal-to-noise ratio.

The working principle of the CDRH10D48/ANP-8R7MC are simple. It is a passive component and makes use of the self-inductance of a coil to maintain a constant or variable inductance over a specific frequency range. When a current flows through the wire of an inductor, it creates a magnetic field which increases the inductance of the coil. This increases the self-inductance of the coil and decreases the opposition to changes in current. Therefore, the current can flow freely through the coil without generating a large voltage drop.

The CDRH10D48/ANP-8R7MC series fixed inductors are extremely reliable and can be easily fitted onto standard surface-mount pads. They also feature a stable inductance over temperature ranges, allowing them to be used in a variety of applications. The inductors are also resistant to moisture and have a low ESR rating. The low ESR ensures minimum power loss and improved signal-to-noise ratios.

In conclusion, the CDRH10D48/ANP-8R7MC series fixed inductors are a high-performance, chip-sized tantalum surface-mount type of fixed inductor. They are suitable for filtering and impedance matching applications, as well as high-frequency tuning. They offer a high Q-factor, stable inductance over temperature, and a low ESR rating, ensuring minimal power loss and improved signal-to-noise ratio. In addition, they are robust and reliable, making them a great choice for many different applications.
