Fixed inductors are components that primarily provide inductance in circuits, which are widely used to generate magnetic fields. The SRR0906-272YL is a fixed inductor that is amongst the popular inductors available in the industry. This article will discuss in detail the application field and working principle of the SRR0906-272YL.

Structural Characteristics

The SRR0906-272YL is a wire-wound SMD type inductor, having a size of 9.0x6.0x3.8 mm and an inductance of 27 uH. It uses the RoHS compliant SLL series ferrite core and features a high Q factor of approximately 23. This fixed inductor utilizes single layered shield form construction, in which secondary windings are placed near the primary winding, and the entire device is sealed in a plastic carrier. Moreover, its fine wire construction provides high resistance to external impacts.

Applications

The SRR0906-272YL is commonly used in pc board circuits with high frequency signals. The device has excellent high frequency characteristics due to its ferrite core and fine grounded construction, so it can be used in applications where high-frequency performance is required, such as audio and control equipment, as well as in mobile communication and automotive applications. The product is also perfect for small, portable electronic devices such as smartphones, tablets, and laptops.

Additionally, the SRR0906-272YL fixed inductor can be used to decouple signals, and for signal input and output. In a power supply circuit, the device can filter noise, eliminate overshoot, reduce ripple, and provide voltage regulation. It is also used in choke coils, EMI filters, transformers, resonant circuits, and other aerospace and military applications.

Working Principle

The SRR0906-272YL works by utilizing the basic principle of inductance, which states that an AC current produces a magnetic field around its wire conductor. This magnetic field creates a voltage across a coil, so the current changes the intensity of the magnetic field over time and this creates a potential difference. This voltage is referred to as inductance. Hence, when a current passes through the SRR0906-272YL, its core acts as an inductor and produces an imbalanced current flow.

Since the SRR0906-272YL has a sealed construction, its internal components are highly protected from external environmental influences. This helps it maintain its stable inductance even when exposed to high frequency, heat, and other high-stress conditions. Furthermore, its ferrite core features low electrical resistivity, which helps the inductor offer superior performance in a wide range of frequencies, as well as in extreme environmental conditions.

Conclusion

The SRR0906-272YL is a fixed inductor commonly used in audio and control device applications, as well as in small portable products such as smartphones, tablets, and laptops. It offers excellent high frequency performance due to its ferrite core and its sealed construction provides sturdy protection from external environmental conditions. Additionally, it can be used for signal decoupling, filtering, and regulation purposes.
