Fixed Inductors

Fixed inductors are passive electric components used for filtering, decoupling, controlling, energy storing and timing applications. Fixed inductors are also known as coils and chokes, and are widely used in industrial and consumer electronics. The fixed inductors used for these purposes are usually rated for a specific amount of current, and can be constructed from a variety of materials, such as copper wire, ferrite, iron, and other conductive materials.

PM20S-R15M application field and working principle

The PM20S-R15M is a popular fixed inductor from Philips, commonly used in communications and control circuits for a variety of applications. This fixed inductor is small in size and exhibits excellent independence of DC bias, which makes it suitable for use in power supplies for distributed systems. It also has a high rated AC current and is well-suited for use in high-frequency power supplies and DC-DC converters.

In terms of its working principle, the PM20S-R15M operates by storing AC or DC current in a magnetic field created by the inductor, which creates a counter electromotive force, or ‘back EMF’. This back EMF reduces the amount of current flowing through the inductor, acting as an AC or DC current limiter. This makes the PM20S-R15M ideal for use in applications such as telecommunications, automatic control, automation, consumer electronics, and more.

The PM20S-R15M is also able to handle a wide range of temperatures, from -40°C to +105°C. Additionally, the PM20S-R15M offers a variety of secondary features, such as a high-temperature reflow solderable construction and lead-free compliant design. This makes the PM20S-R15M an excellent choice for use in applications that require reliable performance over an extended temperature range.

The PM20S-R15M is an excellent choice for a wide variety of applications, offering a small size, low cost, and reliable performance. With its high rated AC current and excellent temperature performance, the PM20S-R15M is suitable for use in distributed systems, power supplies, and other applications that require a reliable inductor.
