Fixed inductors play an important role in capacitor-resistors-inductor (LRC) networks. There are many types of fixed inductors, ranging from very small coils to large temperature-controlled coils, some of which are air-cored and other ferrite-cored. The ISC1210ER2R7J is one example of a fixed inductor. It is a commercially available through-hole inductor with a wide range of applications.

ISM1210ER2R7J Application Field

The ISC1210ER2R7J is a compact surface-mount, low-profile distributed inductor. It is known for its low profile height of 2.7mm and low reactance. It has an inductance range of 1 uH to 10 uH with a tolerance of +/-10%. Its DC current rating is 8A, minimum and with a high saturation current of 20A, it can handle high power applications. It is ideal for use in DC/DC converters, low-voltage supply circuits, switch power supplies, computer motherboards, and as input/output chokes for DC/DC converters.

It is also a popular choice for high-frequency power converters such as inverter control circuits, high-frequency modulated oscillator circuits, and resonator circuits. It is often specified for the power supplies of computers, industrial equipment, medical equipment, and communications systems.

Working Principle

Fixed inductors store electrical energy as magnetic energy. This principle is also referred to as electromagnetic induction. When a voltage is applied to an inductor, a current flows which produces a magnetic field around the inductor. The energy stored in this magnetic field is directly proportional to the amount of current flowing through the inductor. When the current is switched off, the magnetic field collapses and energy is released as an electric current.

The ISC1210ER2R7J operates on the same principle, with the additional benefit of a low profile height which enables it to be placed in tight spaces in power circuits. The low profile makes it an ideal choice for use in recent applications such as smart phones, portable media players, and other devices that require a lot of power but lack room for large components.

The ISC1210ER2R7J is also designed for operations with high frequencies, up to 500MHz in some cases. The high self-resonance of this particular inductor means that it is suitable for high-frequency applications, such as RC filter circuits. It provides excellent stability for the filters in these circuits, allowing the user to achieve the desired frequency response.

The winding of the ISC1210ER2R7J is compliant with the RoHS Directive 2011/65/EU. This means that the materials used in the manufacturing of the inductor are free of hazardous substances and it is therefore safe for use in circuits operating at high temperatures.

Conclusion

The ISC1210ER2R7J by ISL is a low-profile, surface-mount distributed inductor with a wide range of applications. It has a low reactance, a high current rating, and is suitable for use in high-frequency power converter circuits. The RoHS compliant winding ensures that it is safe to use in circuits operating at high temperatures. As a result, the ISC1210ER2R7J is a versatile and reliable fixed inductor, suitable for a range of applications.
