Fixed InductorsFixed inductor is an ideal component for power and RF electronic circuits which requires large current. Inductors are widely used in circuit filters, AC adaptors and power supplies, high-frequency oscillators and etc. SRP1235-1R8M is an inductor that belongs to the SRP1235 series, which is an radial components with built-in ferrite core.SRP1235-1R8M, as a high-power, low-profile, radial lead shield inductor, is suitable for a variety of applications in the 0~100MHz frequency range. It is usually used in power supplies, voltage regulators, step-down circuits, switching power supplies and etc.The SRP1235-1R8M can work stably under harsh environments, including high temperature and pressure. The temperature rating of SRP1235-1R8M is from -55°C to +125°C and the rated current is 1.8A. It is also resistant to moisture, dust and other contaminants and provides a stable inductance in the 0~100MHz frequency range.The main feature of SRP1235-1R8M is its large inductance value, which is 1.8 Henries, at a very low DC resistance of just 0.05 ohms. The large inductance allows this component to achieve high energy storage and current ripple control capabilities. SRP1235-1R8M also has a low saturation current and can be used in a wide range of operating conditions.SRP1235-1R8M consists of an outside cylindrical core made of epoxy resin and ferrite material. There are two sets of windings that are wound with copper or aluminum alloy wire. The windings are then encapsulated in a shell made of polypropylene plastic and insulated with epoxy. This provides the SRP1235-1R8M with superior protection to protect it from external damage such as moisture, corrosion, and short-circuit.The inductance of SRP1235-1R8M can be changed by varying the current passing through the component. When current flows through the SRP1235-1R8M the magnetic field created by the winding of wire will cause the inductance value to increase. However, when the current is removed, the inductance will decrease. Therefore, the SRP1235-1R8M can be used to regulate the power supply output current or to filter out unwanted noise in the circuit.SRP1235-1R8M can also be used in switching power supplies as an oscillator or as a filter inductor. It is mainly used in power supplies, voltage regulators, step-down circuits, switching power supplies, and other high power applications such as power amplifiers. It is used for smoothing current flow as well as providing energy storage for the circuit.In summary, the SRP1235-1R8M is a high-power, low-profile, radial lead shield inductor suitable for a variety of applications in the 0~100MHz frequency range. It is designed to provide high inductance and current ratings in a small form factor and is therefore ideal for applications that require high energy storage and current ripple control capabilities. Due to its resistance to moisture, dust and other contaminants, and its temperature rating of -55°C to +125°C, it is suitable for a variety of harsh environments.
