The SPM5030T-R35M fixed inductor is a type of component designed for consumer electronics, automotive, and industrial applications. It is designed to provide signal filtering, as well as a range of other functions. It is a non-polarized device and can be used for many types of circuits, such as power supplies, voltage regulators, and audio amplifiers. This inductor is rated for 35 mmH resistance at 25ºC and has a maximum operating temperature of 125ºC.

The SPM5030T-R35M is a flat spiral winding of thick insulated wires. The ends of the winding are connected to a core of copper or ferrite material to form a complete circuit. The core and the winding are integrated and protected by an enclosed plastic or metal case. The case not only contains the parts but also protects the winding from damage due to vibration or harsh operating conditions.

The inductance value of the SPM5030T-R35M is determined by the number of turns of the coil and the core material used. By increasing the number of turns the inductance will increase, or if a ferrite core is used then the inductance will also be higher than if a copper core is used. In either case the current that can be supported by the inductor is still limited by the core material.

The SPM5030T-R35M is ideal for high frequency switch-mode power supplies, PFC, DC-DC converters, high-end audio amplifiers, and other PC board applications. Its small size also allows it to be used in tightly packed components, thus helping to minimize footprints in boards. The flat design is better suited for high density, high current applications as the uniform flat winding provides a more even magnetic field distribution around the inductor.

The working principle of the SPM5030T-R35M is simple. When a varying current or voltage is applied, the inductor will inject a counter electromotive force to oppose the changing current. This opposes the electrical change, causing the secondary voltage to lag behind the source voltage. By using the magnetic flux to oppose the input current, the inductor will effectively filter the input from the output.

The SPM5030T-R35M is an excellent choice for many consumer electronic and automotive applications. Its small size and high-frequency response make it an ideal choice for many of these applications as it can be mounted in tight spots to conserve space and still offer the level of performance needed. Its wide operating temperature range and low core saturation current make it suitable for a variety of applications in harsh environments.
