Fixed inductors are a key component in many electronic circuits. From capacitors and resistors to transistors and diodes, they are all essential components of the electronic system. An inductor, by definition, is a two-terminal device that stores energy in a magnetic field when current flows through it. It consists of a coil of wire wound around a core material, usually ferrite or iron, which are immersed in a liquid or powder-based magnetic material. The coil of wire is the inductor’s windings.

In electronics, inductors are classified as either fixed inductors or variable inductors. Fixed inductors are relatively inexpensive compared to their variable inductors counterparts. They are also typically used in more basic applications. Fixed inductors typically feature larger diameters, which makes them useful for applications that require high inductance. The SL1923-103KR33-PF, for example, is a surface-mount fixed inductor that is ideal for applications such as switching power supplies, EMI filters, RF circuits, and battery chargers.

The SL1923-103KR33-PF is a wire-wound, unshielded, three-terminal surface-mount fixed inductor with a maximum operating temperature of 125°C. It has a 2.2mm maximum body diameter. This inductor features an inductance range from 10 to 330nH, a contact resistance between 0.67 ohm to 13 ohm, and a saturation current between 5.83A and 330mA. It has a low DC resistance and a low electrical noise of low frequencies. It is rated for up to 3.5A electrical current and is available in either a 0603 or 0805 package.

The working principle of the SL1923-103KR33-PF is relatively simple. When a direct current is applied to the inductor, a magnetic field is created, and the current also creates a voltage across the inductor (Lenz’s Law). The inductor stores the energy of the magnetic field and the current in the inductor also creates an induced voltage in the opposite direction (Ferromagnetic material). Thus, the voltage across the inductor will vary depending on the current applied. This is why the inductor acts as a filter in many applications.

The SL1923-103KR33-PF is suitable for an array of applications, including switched power supplies, DC-DC converters, EMI / RFI suppression, inductors for high-performance DC-DC converters, as well as battery chargers for laptops and other mobile devices. It is also useful in digital audio systems and frequency dividers. It can be used in circuits where high currents and high frequencies are required.

In summary, the SL1923-103KR33-PF is a wire-wound, unshielded fixed inductor with a maximum operating temperature of 125°C. It has a low DC resistance and low electrical noise of low frequencies. It is suitable for high current, high frequency applications such as switched power supplies, DC-DC converters, battery chargers, EMI / RFI suppression, and other applications. It is an ideal choice for electronic circuit designs that require high efficiency and low losses.
