outline
With the development of intelligent devices, the demand for various portable electronic devices emerges, which requires more miniaturization and more stable performance of components. In particular, as an important component of product power management application, inductance requires miniaturization on the premise of ensuring performance in the component design of intelligent equipment. After learning the market application demand, Xiangru Electronics developed a miniaturized integrated inductor XRTC252010S2R2MBCA suitable for small-size applications requiring large current, with an inductance value of 2.2μH, a size of only 2.5mm×2.0mm×1.0mm, and a typical rated current of up to 2.4A, which can meet the application demand of miniaturized power supply for various intelligent devices.

Innovative technology
Adopt integrated molding process to improve electromagnetic characteristics.
As shown in the structural diagram of Figure 3, XRTC252010S2R2MBCA adopts an integral molding process, and the external part is molded by metal powder, and the internal coil, electrode and T-core are encapsulated to form a stable electromagnetic structure, which reduces the magnetic leakage of the product and has more stable characteristics.

Strong current capacity and stable inductance characteristics.
As can be seen from Figure 4, XRTC252010S2R2MBCA maintains stable inductance characteristics, with a typical rated current of 2.4A, but the inductance value will be attenuated with the increase of current, so it is recommended to use it at a typical rated current. At the same time, under the condition of rated typical current, the temperature rise will not exceed 30℃, and the temperature will rise sharply under the condition of overcurrent, so it is necessary to pay special attention to the design and refer to the information in Figure 4.
Strong product reliability
XRTC252010S2R2MBCA of Xiangru Electronics is worthy of users' trust in reliability. Its insulation resistance is ≥100MΩ, and more than 90% of the electrode area is available for welding, which can form a firm connection with PCB. At the same time, the product passed the temperature test and impact test at -55℃~125℃, and there was no trace of deformation or damage on the surface. In addition, Xiangru Electronics also carried out humidity and life tests, and the inductance value changed within 10%. Through strict test data, the product has the ability of domestic independent replacement in the smart product industry, which is worthy of users' trust.
