Fixed Inductors

Inductors are passive electronic components that are used to store energy in the form of an electrical current and magnetic field. A fixed inductor, also known as an inductor core, is a type of inductor that does not change its inductance value over time. The VLF504010MT-4R7M-CA, a part of the Vishay Intertechnology family of products, is an example of a fixed inductor.The VLF504010MT-4R7M-CA is a surface-mount, low-profile inductor. It is a loop-style device that is composed of a flat ferromagnetic core surrounded by a coil of conductor. It is designed for applications that require high impedance and low profile, such as circuit boards with limited space. The VLF504010MT-4R7M-CA has a rated inductance of 4.7 μH ±10%, a maximum current rating of 0.44 A, and a frequency range of up to 500 kHz. The working principle of the VLF504010MT-4R7M-CA is based on the guiding principle of electromagnetism. When a steady current passes through the coil, it creates a magnetic field which in turn induces a counter-electromotive force (emf) in the same coil. This back emf opposes the changing magnetic field, resulting in the protention of energy and creating an inductance. In a fixed inductor, the inductance remains fixed and does not vary with the changing current or voltage.The applications of the VLF504010MT-4R7M-CA are numerous. It is often used in electronic circuits as a buffer. When connected in series, it acts as a low-pass filter, allowing only low-frequency signals to pass through. It is also used in high-frequency switching circuits, in which it helps to reduce voltage spikes and control EMI. The VLF504010MT-4R7M-CA is also commonly used in power supplies, amplifiers, and oscillators.In conclusion, the VLF504010MT-4R7M-CA is a high-quality, low-profile inductor from Vishay Intertechnology. It is a fixed inductor whose inductance remains constant regardless of the changing current or voltage. The versatile applications of the VLF504010MT-4R7M-CA include buffer circuits, low-pass filters, high-frequency switching circuits, power supplies, amplifiers, and oscillators.
