The fixed inductors are components used in a variety of applications that require a fixed, stable current or voltage. The SPD62R-122M is a fixed inductor designed for DC/DC power conversion applications. It is ideal for applications such as DC to DC converters, power supplies, H-DACs, and voltage regulation modules.The SPD62R-122M is a multi-layer, non-toroidal inductor that provides a stable current and voltage when connected to the power source. Its construction features two vertical long ferrite rods inserted into the ceramic core. The ferrite rods are held in place by four metal pins which interlock and provide a maximum number of winding layers for good magnetic shielding. The ferrite rods are made out of nickel-zinc ferrite, and the outer casing is made out of an epoxy resin. This combination of materials allows the inductor to withstand a wide range of temperatures while providing high efficiency.The inductor is designed to operate at frequencies ranging from 15 kHz to 800 kHz. At the lower frequencies, the inductor is suitable for applications with high inductance, such as DC motors and power supplies. The higher frequencies make it suitable for applications where low inductance is required, such as H-DACs and switching regulators.The inductance is determined by the number of windings and the diameter of the ferrite rods. Along with this, the inductance value also depends on the dielectric constant, temperature coefficient, and winding insulation resistance.The SPD62R-122M features a low temperature coefficient, which provides excellent stability over a wide operating temperature range. It also features a high efficiency rate of up to 98 percent, which reduces power losses and increases power transfer from the source to the load.In addition, the inductor has a self-healing property. This means that the winding wires of the inductor are designed to automatically reconnect if they are disconnected due to an overload. This property is important as it increases the reliability of the component, especially in power conversion applications where the current can be high.The SPD62R-122M is an ideal choice for applications that require a fixed inductance and voltage with low noise levels. It is highly reliable and has a long life expectancy, due to its robust construction and self-healing property. Its high efficiency makes it suitable for power conversion applications where heat dissipation and power loss are of great concern. Finally, its low temperature coefficient makes it a good choice for applications in extreme temperature environments.
