Product summary
Nowadays, the miniaturization design of electronic products is generally regarded as a consensus trend in the electronic industry, which has deeply promoted the evolution of its internal electronic components in a more compact and efficient direction. In the process of miniaturization of electronic products, engineers have to deal with a series of complex and severe challenges, including but not limited to the key problems such as the construction of efficient heat dissipation mechanism, the optimization of power management, the suppression of signal interference and the control of noise level. With its excellent independent research and development capability, Xiangru Electronics grandly launched the miniaturized integrated inductor XR0420-4R7M. With its miniaturized volume, high rated current carrying capacity, excellent electromagnetic shielding performance and extremely low energy consumption, this product has become an ideal choice for all kinds of miniaturized products with limited space, and is widely used in AV equipment, OA equipment, home appliances, information services and other electronic equipment.
Product features

Product advantage
1. Miniaturization design concept
XR0420-4R7M is small in size and high in dimensional accuracy, which perfectly meets the requirements of patch installation, effectively improves product integration and conforms to the development trend of miniaturization of modern electronic equipment.
2. Accurate perception
Inductance parameters are very important in circuit applications that require high accuracy of inductance values. XR0420-4R7M sensor uses the instrument Tonghui TH829A@25℃ 1KHz/0.3V, the measured value is 4.7μH, and the tolerance is controlled to 20%, which can ensure the high consistency of product sensitivity.
3, ultra-low DC impedance DCR
The product DCR uses the instrument Tonghui TH829A, and the maximum measured DC impedance of the circuit board is only 112 mω. The lower DCR effectively reduces the circuit loss and improves the working efficiency of the system.
4, high rated current
The rated current is measured at 2.2A with the instrument E1412A, and the tolerance is stable at 5%, which ensures excellent temperature rise current and saturation current characteristics in high-frequency and high-temperature environments.
5. Comprehensive technical data
Xiangru Electronics provides comprehensive technical data and detailed conditions of use, which increases the credibility of products and helps to enhance the trust and cooperation between users and manufacturers. Xiangru provides technical support, which can effectively solve the user's device selection and optimize product design, thus shortening the product development cycle and saving costs.
