Fixed Inductors

Fixed inductors are passive electronic components used to store energy in a magnetic field. These components consist of metal conductors wrapped around a core material, typically ferrite. The stored energy is proportional to the current or voltage applied to the inductor. Inductors are most commonly used for filtering signals, in power supplies, and motor control applications.The SP1812R-102K is a fixed inductor developed by TDK Corporation. The product is an axial leaded SMD power inductor with a high current rating of 102A and an inductance of 1.8µH. Its construction is a composite of four layers of ferrite and five layers of winding.The SP1812R-102K is ideal for use in a wide range of consumer electronic products. Its high current rating makes it suitable for high current PWM motor drives, SLICs, and switching power supplies. The small size of the component, combined with its low profile, makes it ideal for applications with limited board space.The SP1812R-102K employs a ferromagnetic core material to facilitate the storage of magnetomotive force. This magnetic field can be generated by the electric current present in the inductor or induced by electro-magnetic radiation. The stored energy creates a voltage across the coil which in turn induces a current in the component. This is the principle on which inductors operate. The component is designed to handle up to 102A of current without any operational problems. It is rated at a temperature range of -40°C to +85°C, with an operating frequency of up to 50kHz. Furthermore, the component is designed to handle a wide range of ripple current and is certified as UL, CSA, and VDE approved.When designing applications where the SP1812R-102K is used, it is important to take into account the component’s temperature rise characteristics. The voltage rating should also be taken into account, as any surge above the specified peak voltage can cause damage to the component. Furthermore, operating frequency should be limited to the component’s specified operating frequency to maximize performance. Overall, the SP1812R-102K is a reliable and efficient induction component that can be used in a variety of consumer electronic applications due to its high current rating, small size, and low profile. Its good temperature and surge voltage characteristics make it ideal for high-end applications, while its wide range of ripple current handling capabilities make it suitable for a range of consumer electronics.
