Introduction: Fixed inductors, also known as choke coils, are composed of wound wire around a ferrite or iron core. Much like a transformer, they are used to store and transfer energy between circuits, through inductive content.

CTX100-2-52M-R: The CTX100-2-52M-R is a fixed inductor specifically designed for very small size SMD applications. This component features a characteristic impedance of 100Ω and an inductance value of 2.52mH. The component has a maximum current rating of 8.2A and maximum DC resistance of 0.5Ω. Additionally, this product is able to withstand the soldering heat of 300 degrees Celsius for 10 seconds.

Application Field:

The CTX100-2-52M-R fixed inductor can be used in many different applications, depending on the desired characteristics. Common applications include:

• Power supply filtering and inrush current suppression in consumer electronics, such as PCs, servers and TVs.
• DC to DC converters.
• Inverters.
• Switching power supplies.
• EMI and EMI suppression circuits.
• Audio and digital circuits.
• Battery charging circuits.

Working Principle

As with many inductors, the CTX100-2-52M-R works by inducing a large back-EMF (electromotive force) in the circuit when a changing current passes through it. This back-EMF acts like a large resistor, limiting the current flow in the circuit, which causes a filtered power to flow through the circuit. Since the inductance of the component is fixed at 2.52mH, the resulting filtered power will be constant.

By this method, the inductor acts as a low-pass filter, allowing only low-frequency signals to pass through and blocking high-frequency signals. This helps to reduce or eliminate electromagnetic interference, which can cause damage to other components or degrade the signal quality. Additionally, the back-EMF also helps to reduce or eliminate voltage spikes or ripples, which could cause damage to other components.

In some cases, the CTX100-2-52M-R can be used as a voltage step-down transformer, to convert higher voltages into lower voltages, due to its high current rating and temperature resistant construction. This is especially useful in battery charging circuits, as well as inverters and switching power supplies, where a lower output voltage is desired.

Conclusion

The CTX100–2–52M–R is a fixed inductor ideal for use in very small SMD applications. Its low DC resistance, high current rating, and temperature resistance makes it suitable for use in many different types of applications. This component is most commonly used for power supply filtering and inrush current suppression, DC to DC converters, inverters, switching power supplies, EMI suppression circuits, audio and digital circuits, and battery charging circuits.
