Fixed inductors are electric components composed of a wire winded on an iron core in which a steady current passes through in a linear circuit. PM105‑681K is one type of fixed inductors. The inductor is a power inductor with a wide range of applications due to its high saturation current of 105A and small footprint.

This product features inductance of 680µH, maximum current of 105A and a nominal operating temperature range of −40°C to +105°C. It is RoHS compliant and has a high energy storage capacity. The external dimensions of the product are 27.0mm x 17.0mm x 14.8mm with a weight of only 22.4g making it suitable for space-constrained applications.

The PM105‑681K is ideal for applications such as computer monitors, switches, amplifiers, medical imaging systems, home theatre systems, consumer electronics, and motor speed control. This product is constructed with a superior magnetic shield to provide excellent EMI suppression. The magnetic material used also ensures low radiated magnetic noise.

The inductor\'s working principle is based on the law of induction, according to which a magnetic field is generated around a conductor when a current passes through it. The changing magnetic field induces a current in nearby conductive material, thus generating an electrical energy. The generated electrical energy in the inductor is dissipated without reaching the source, providing the required reliability and stability.

The PM105‑681K is manufactured using high quality materials which guarantee maximum performance and longer life of the product. The magnetic core is made of ferrites which coat with a plastic material for effective insulation and improved performance. The coils are made from an alloy for superior energy storage capacity.

Moreover, the product has excellent current handling ability due to optimized winding on the non-conductive core material. This guarantees minimal voltage ripple at high frequencies and low loss. The use of efficient power inductors helps to minimize size, weight, and cost without sacrificing performance.

In conclusion, the PM105‑681K fixed inductor from Power Magnetics is a reliable and versatile product which can be used in a variety of applications due to its excellent features. It offers excellent performance, maximum current handling capability, low loss, and high energy storage capacity. Its superior design increases the product’s efficiency and reliability, making it an ideal choice for designers who are looking for superior quality and performance in their components.
