Patch SMD 1R9 Chip Power Inductor Flat Line High Current Integrated Inductor

 1.Product Description

A 1R9 Chip Power Inductor is a compact and highly efficient power - handling component in modern electronic circuits. The "1R9" denotes its inductance value, with "R" representing the decimal point, meaning it has an inductance of 1.9 microhenries (μH). This value is carefully calibrated to meet the specific requirements of power - related applications.

The "Chip" in its name indicates its surface - mount chip - type package. This design allows for easy integration onto printed circuit boards (PCBs), significantly reducing the overall size and weight of the circuit assembly. It takes up minimal space on the PCB, making it ideal for miniaturized electronic devices such as smartphones, tablets, and wearable electronics.

As a power inductor, it plays a crucial role in power management systems. In switching power supplies, which are widely used in various electronic devices to convert electrical energy efficiently, the 1R9 Chip Power Inductor stores and releases energy during the switching cycle. It helps to smooth out the current flow, reducing voltage ripple and ensuring a stable power output. This is essential for protecting sensitive electronic components from voltage fluctuations and ensuring the proper functioning of the entire device. Its high - current - handling capability also enables it to support power - hungry components in the circuit, making it a vital part of modern power - efficient electronic designs.

2.Application

1. Compact size, easy to integrate: Surface mount packaging has a very small volume and can occupy very little space on a printed circuit board (PCB), making it very suitable for small-sized electronic products with strict space requirements, such as smart watches, wireless headphones, etc. This compact size allows for high-density layout on PCBs, allowing electronic products to accommodate more functional modules in limited space, which helps achieve device lightweight and miniaturization.

2. Accurate inductance value and stable performance: The inductance value of 1.9 μ H has been precisely calibrated, providing stable inductance performance for various circuits. Accurate inductance value is crucial for stable power conversion and voltage regulation in DC-DC converters of power management circuits, helping to ensure stable power supply for electronic devices, reduce the impact of voltage fluctuations on device performance, and improve device stability and reliability.

3. Strong current carrying capacity: With high current carrying capacity, it can meet the power demand of high-power components in electronic devices. In the power supply circuit of components such as the central processing unit (CPU) in high-performance laptops that require high current, it can provide stable high current to ensure the normal operation of components under high load, without performance degradation due to insufficient current supply.

4. Low DC resistance and high efficiency: The low DC resistance reduces the heat loss generated when current passes through, reduces energy waste during transmission, and improves the overall efficiency of the circuit. Lower power consumption not only reduces energy consumption, but also reduces the heating problem during device operation, which helps to extend the service life of inductors and other components in the entire system.

5. Excellent frequency response and good filtering effect: It has excellent frequency response characteristics in high-frequency environments, especially in high-frequency switching power supplies. It can effectively filter out high-frequency noise and provide pure and stable power output for electronic components sensitive to electromagnetic interference, ensuring that electronic devices are not affected by high-frequency noise and maintaining good working conditions.
