<p>Fixed inductors are used in an array of applications and provide efficient magnetic energy storage. The CR75-470KC is one such example of a fixed inductor. This component is also referred to as a toroid inductor, and it is widely used in switched-mode power supplies and other applications where a constant current is needed. It is also useful in RF circuits, where its ability to suppress harmonics and transients is an added bonus.</p> <p>The CR75-470KC is a radial leaded, non-polarized, axially mounted, ferrite core toroidal inductor. It has a high maximum current rating of 0.07A/2W for a typical 470uH inductance. It has an inductance range of 4-360 uH, with a high self-resonant frequency of 6.5GHz. The component is available in two sizes, with the larger size being 48.6mm long and 18.2mm in diameter.</p> <p>The CR75-470KC operates at a wide temperature range of -40 to +90°C. It has a low thermal resistance of 10°C/W and is suitable for both common-mode and differential-mode suppression. It also has a low DCR for maximum efficiency and high impedance for maximum RF noise reduction. This makes it ideal for RF applications such as radio transmitter circuits, RF receivers, and circuit protection.</p> <p>The CR75-470KC has a unique working principle. It utilizes the properties of ferromagnetic materials to produce a steady “eddy” current, which is formed when a magnetic field created by electric current, passes through a conductor with low impedance. This magnetic field induces a voltage in the toroidal core, which increases with the current. The increased voltage produces a counter-emf, which opposes the original current, limiting the current flowing through the inductor. </p> <p>The CR75-470KC is a versatile component and is used in a variety of applications. It is often used in power supplies for voltage regulation, especially in switched-mode power supplies. It is also useful in RF and microwave circuits for impedance matching and harmonic filtering. Lastly, the CR75-470KC can be used for circuit protection in equipment such as amplifiers and radio transmitters.</p> <p>The CR75-470KC is a reliable and cost-effective component, and it is a great choice for those who need a steady, high power, DC current with minimal noise. Its low DCR and high impedance also make it suitable for RF applications. As such, it can be used in a range of applications, and it is a good choice for anyone who requires a fixed inductor.</p>
