Fixed inductors are electrical components designed to resist the flow of current and store energy in a magnetic field. The MS75087-6ST is a type of fixed inductor, particularly a non-polarized surface mount wire-wound inductor designed for use in a variety of applications. This article will discuss the application field and working principle of the MS75087-6ST.

The MS75087-6ST is a wide-range current sense inductor. It is designed to accurately sense current levels over a wide range. It allows for precise current measurement, with minimal distortion of the rail, and is well-suited to current-limited applications. This includes power supply or battery management applications, and audio applications such as amplifiers, receivers, or portable speakers. The MS75087-6ST is also suitable for automotive applications, and can be used in a wide variety of other applications such as light-bulb dimmer circuits, fault detection in motor drive circuits, and DC-DC converters.

In terms of its physical design, the MS75087-6ST is composed of 6 strands of copper wire wound together around a magnetic core. It is 6.5mm in length and 4.3mm in width, and is available in a range of inductance values. It is rated for up to 2 watts of power and has an operating temperature range of -55 degrees Celsius to +125 degrees Celsius. It has a maximum DC current of 0.5A and a maximum AC current of 450mArms, with a peak flux density of 1.3 Tesla.

The MS75087-6ST also has very low noise levels and low stray fields. This means that it is capable of handling very small signals without distortion. It also has good high frequency response, with a self-resonance frequency of 25MHz and a minimum frequency of 500kHz. This makes it suitable for applications such as power supplies and audio amplifiers, where significant high frequency performance is required.

In terms of its working principle, the MS75087-6ST functions as an impedance ratio transformer. This means that it produces an output voltage proportional to the input current, by leveraging the relationship between current and magnetic flux. This is achieved through Faraday’s law of induction, which states that an electromotive force (EMF) is induced in a conductor when it is exposed to a changing magnetic field.

When current passes through the MS75087-6ST, it creates a magnetic flux that induces a voltage across the inductor’s two leads. This voltage is proportional to the current flowing through the inductor, and is what allows it to function as a current sense inductor. This is also what allows it to be used in applications such as power supplies, audio amplifiers, and motor drives, where accurate current sensing is required.

The MS75087-6ST is a versatile and reliable fixed inductor designed for use in a variety of applications. Its wide range current sensing capabilities, small size, and low noise levels make it an ideal choice for current-limited applications, applications requiring high frequency performance, and automotive applications. With its robust design and reliable performance, the MS75087-6ST is an ideal solution for applications demanding accurate current measurement over a wide range.
