On the occasion of the second anniversary, breaking through the dilemma of low inductance values in small form-factor inductors
In the above, we mentioned that there are many kinds of inductors, such as integrated molding, NR magnetic adhesive winding type, precision winding type, laminated printing type, etc. Different kinds of power inductors are suitable for different terminal products. Among them, the small integrated inductor has the characteristics of large current and low internal resistance, and its overall characteristics are excellent. It is the best choice for high-performance miniaturized terminal products, but its disadvantage is that its inductance value is low, which cannot be applied to products with smaller current, such as Bluetooth headsets, smart wearable products and micro communication modules.
As far as inductance is concerned, the calculation formula of inductance value is l= (k × u × N × S)/l, where "N" represents the number of turns of coil, which has a square relationship with inductance value. Under the urgent need of inductance miniaturization, due to process limitations, the smaller the volume, the less the number of coils wound inside it will be, resulting in a sharp drop in inductance value. For smart wear, Internet of Things, Bluetooth headsets, portable microphones, micro communication modules and other terminal products, both small size and high inductance power inductors are needed to improve the overall performance, which has become a technical bottleneck.

To solve this problem, on the occasion of the second anniversary of its establishment, SCIENTIC launched SIRB Series small integrated power inductor with high inductance value, which supports the highest inductance value of 15uh at the size of 1608, which is more than three times higher than the previous highest inductance value of 4.7 uh at the size of 1608 small integrated power inductor in the world. In many miniaturized Internet of Things products, communication modules, wearable products, TWS headphones, neck-mounted headphones, microphones and other products, the output power is small, the switching frequency is relatively low, and besides core voltage, there are loads with higher voltages such as 1.8 V, 2.5 V and 3.3 V. According to the calculation formula of the optimal inductance range of the power inductance of the switching power supply, the voltage is directly proportional to the inductance value, and the load current is inversely proportional, so the inductance with high inductance value is needed to have better efficiency performance and more stable output voltage. The arrival of SIRB Series will redefine the selection principle of power inductor and bring better overall performance for such applications.
With the rapid development of electronic products and the outbreak of emerging markets such as Internet of Things, smart wear and smart home, the market demand for inductance products is steadily expanding. With the upgrading of product experience and richer functional applications, the number of inductors required by a single product is also multiplying, and inductor products still have broad development space in the future. SCIENTIC company, as a manufacturer in the field of inductors, has only been established for two years, but based on the professional R&D team and the spirit of scientific exploration, it constantly breaks through the existing product barriers, creates better power inductors, and provides better solutions for the application of end products.
