SDR1030-220M

Fixed inductors are electrical components designed to provide a near-constant current when powered at a given frequency. A fixed inductor is sometimes referred to as a coil due to its physical structure, and is most commonly found in radios, televisions, and other electronic devices. In general, the main function of a fixed inductor is to provide inductive reactance, or an opposition to alternating current that is proportional to frequency, and the output voltage is directly related to the input power. The SDR1030-220M is a type of fixed inductor specifically designed for applications in the range of 10kHz to 30MHz.

The SDR1030-220M has a coreless construction consisting of a carbon-filled ferrite material and an efficient combination of windings for optimum inductance and quality factor (Q). The product has a low insertion loss, making it an excellent choice for medium power applications. Additionally, its frequency range from 10kHz to 30MHz makes it suitable for mobile communications and short-range applications such as HF radio.

The operating principle of the SDR1030-220M is based on Faraday\'s law of induction, which states that when the current through a conductor changes, a magnetic field is created around the conductor that induces an electric field in its vicinity. This electric field is also known as an EMF, or electromotive force, which acts upon both moving and stationary charges and can be used to create a voltage. In the case of the SDR1030-220M, this voltage is generated by changing the current through the inductor itself, thus creating an oscillating magnetic field, which induces a voltage in a capacitor connected in series with the inductor.

As the frequency of the current changes, so does the EMF generated by the inductor, creating a frequency-dependent effect. This frequency-dependent effect is known as inductive reactance, which can be used to create a filter-like effect when two or more inductors are connected in series. The SDR1030-220M is designed to take advantage of this effect, allowing for accurate and predictable results when used in short-range applications.

Furthermore, the SDR1030-220M is designed for medium-power applications, meaning that it can handle up to 220mA of current without damaging the component. This makes it a good choice for applications that require moderate levels of power, such as cell phone antennas, wireless communication components, and other short-range applications. The product is also highly resistant to thermal shock and shorts, ensuring long-term reliable operation.

In short, the SDR1030-220M is a fixed inductor specifically designed for applications in the range of 10kHz to 30MHz. It is constructed of a carbon-filled ferrite material and an efficient combination of windings for optimum inductance and Q factor, resulting in low insertion loss. Its operating principle is based on Faraday\'s law of induction, which produces an EMF proportional to the frequency of the current, resulting in a frequency-dependent effect known as inductive reactance. Additionally, it is designed for medium-power applications up to 220mA, making it a good choice for cell phone antennas, wireless communication components, and other short-range applications.
