Fixed Inductors

Fixed inductors, or fixed-value inductors, are electronic components that have a specific inductance and hence a specific purpose. AISM-1210-2R7K-T is one such fixed inductors, and in this article we’ll be discussing its application field as well as its working principle.

AISM-1210-2R7K-T Application Field

AISM-1210-2R7K-T is a multi-layer air-core inductor component optimized for use in micro-electronic applications. It features both high inductance and low DCR values ranging from 3.9 – 7.8 µH, with the DCR falling in the range of 2-12mΩ. This range makes it suitable for a variety of applications, both in terms of powered and unpowered devices, as follows:

• Audio/speech equipment, such as amplifiers, headsets, and noise cancelling devices.
• RC filters for low-frequency response.
• DC-DC down converters.
• Low-frequency high-amplitude signal amplifier.
• High-current switching.
• Modems or such applications where high-speed data transfer is required.
• High-frequency communication applications.
• Data converters.
• The design of high-precision low-voltage analog circuits.

AISM-1210-2R7K-T Working Principle

AISM-1210-2R7K-T fixed inductors utilize the principle of inductance to generate a magnetic field from current. When a current is applied to the inductor, it creates a magnetic field. This magnetic field interacts with the current, creating a counter force on the current, called inductance. This counter force will reduce the rate of current flow if the current is changing, and can also be used to store energy.

The inductance of the AISM-1210-2R7K-T is measured in units of ohms, with each ohm representing a unit of stored energy in the magnetic field. The DCR (Direct Current Resistance) of AISM-1210-2R7K-T ranges from 2-12mΩ, which is less than the in-circuit values of other inductors, allowing the AISM-1210-2R7K-T to convert energy more efficiently and with a lower resistance.

The the AISM-1210-2R7K-T also features a high quality factor, allowing for efficient transduction between current and magnetic fields. This allows the inductor to be used in applications with higher frequency and voltage requirements, such as audio and video applications.

Conclusion

In conclusion, fixed inductors, such as the AISM-1210-2R7K-T, are widely used in a variety of applications, due to their low DCR, high quality factor, and high inductance. With its range of features, the AISM-1210-2R7K-T can be used for both powered and unpowered devices, in a variety of high-frequency or low-voltage applications.
