Fixed Inductors

A fixed inductor, also known as a radio frequency choke, is an electronic component used in many electronics circuits. It is made up of a core of two wires, a rolled up wire, and a capacitor. It works by blocking certain frequencies while allowing others to pass through. The UP1B-470-R fixed inductor is a common type of fixed inductor. It is manufactured by Vishay Semiconductor and is found in many types of electrical and electronic devices.

UP1B-470-R Application Field

The UP1B-470-R fixed inductor is used in a variety of applications. Commonly, it is used in diode-bridge rectifier circuits, in parallel connection with diodes to reduce high harmonic distortion, and in circuit designs to reduce the impedance of high frequency signals. It is also often used in high frequency switching circuits like buck converters, and to provide efficient and frequent high frequency DC choke attenuation. Additionally, it is used in variable frequency converters to maintain an even level of AC voltage or current.

UP1B-470-R Working Principle

The UP1B-470-R fixed inductor works in the same way that all inductors work. It blocks certain frequencies while allowing others to pass through. The device contains a core of two wires that are coiled together around a ferromagnetic material. When electric current is passed through the wires, it produces a magnetic field with lines of flux, which generate an opposing voltage that is proportional to the rate of change of current flow. This opposing voltage limits the flow of current to the coil, providing resistance. Due to its high resistance, the UP1B-470-R fixed inductor blocks high frequency signals and allows lower frequency signals to pass through.

UP1B-470-R Specifications

The UP1B-470-R fixed inductor has a single inductance of 470uH. It can handle a maximum power rating of 960mW with a temperature stability of +/- 20%. The maximum winding temperature is 400°C and the insulation resistance is 1000 megohms minimum at 500V DC. The operating temperature range is -25°C to +85°C.

Final Thoughts

The UP1B-470-R fixed inductor is a versatile component, used in a variety of applications. It works by blocking certain higher frequencies while allowing lower frequencies to pass through. Due to its high resistance, it can reduce harmonic distortion and provide high frequency DC choke attenuation. It is able to operate efficiently over a wide temperature range, making it an ideal choice for many circuits.
