1.Product Description

The 4R7M SMT Chip Inductor, with an inductance value of 4.7 microhenries (denoted as 4R7), is a prevalent surface - mount technology (SMT) component in the electronics industry. Engineered to endure substantial electrical currents, it's well - equipped to handle the power demands of numerous circuits. Its SMT chip design allows for easy integration into compact printed circuit boards (PCBs), making it a top choice for space - constrained applications like wearable devices, miniaturized medical electronics, and wireless modules. This inductor features a magnetic shielding design, effectively curbing electromagnetic interference (EMI) and ensuring stable operation even in noisy electrical environments. The "M" in its name typically indicates a certain tolerance level, providing reliability in performance. With low DC resistance, it minimizes power dissipation, enhancing the overall efficiency of the circuits it's incorporated into. It serves a pivotal role in power conversion circuits, such as DC - DC converters, for regulating current and voltage, and is also vital for filtering out high - frequency noise in various electronic systems, guaranteeing clean and stable power supply.

1.Excellent electrical performance guarantee
--Precise inductance matching: The inductance value of 4.7 microhenry (4R7) provides precise matching for various circuits. In the power supply filtering circuit, it can effectively filter out specific frequency interference signals, like in the switching power supply output, the accurate inductance value ensures that the high frequency noise is greatly attenuated, providing pure power for the load and guaranteeing the stable operation of the equipment.

--High current-carrying capacity: strong current-carrying capacity to meet the high-current requirements of various circuits. In the power amplifier circuit, it can stably transmit large current to ensure that the audio signal is not distorted and amplified, and maintain the circuit to work stably under different loads, avoiding performance degradation caused by insufficient current.

-Low power consumption operation: low DC resistance characteristics, greatly reducing the power loss when the current passes through. In long-time running electronic equipment, it reduces energy waste, lowers heat generation, prolongs the service life of the equipment, and improves energy utilization efficiency, which is in line with the requirements of energy saving and environmental protection.

2. Adapt to multiple application scenarios
--Compact space adaptation: SMD chip design makes it compact and easy to integrate into circuit boards with limited space. In wearable devices such as smartwatches, the inductor can effectively utilize the space in the narrow internal space to achieve a variety of functional circuit layouts, helping to miniaturize the product.

--Stable operation in complex environments: Magnetic shielding design effectively suppresses electromagnetic interference. In the complex electromagnetic environment in which industrial control equipment is located, it can ensure that it is free from external interference and work stably, while avoiding interference with other electronic components in the surrounding area to ensure the stable operation of the entire system.

3. Reliable product quality
--Stable and reliable performance: The specific tolerance level represented by “M” makes the inductance fluctuate within a certain range without affecting the normal function of the circuit. Under different temperature, humidity and other environmental conditions, the inductors can still maintain stable performance, reducing circuit failures caused by environmental changes and improving product reliability.

--Mature and durable process: Mature manufacturing process and high quality materials ensure that the product has good mechanical strength and electrical stability. In the process of product assembly, transportation and long-term use, it is not easy to appear pin breakage, performance degradation and other problems, reducing the product after-sales maintenance costs.
