Fixed InductorsFixed Inductors are components of electronics and electrical systems that generate, maintain, store or balance energy flows. These electrical elements are available in a variety of shapes, sizes and materials with different operating parameters, characteristics and ratings. One particular type of Fixed Inductors,SRN3015-100M, has an interesting application field and working principle that has been widely accepted in recent years.SRN3015-100M is a highly efficient, low-profile, low-resistance, high-inductance fixed inductor. It is based on a 4-layer printed circuit board and has a distinctive construction that includes two copper windings with cross-over between the two. The fixed inductor provides high performance in a compact form factor and is designed for a wide range of electronic applications requiring very low DCR and high Q in a wide range of inductance values. It is commonly used in switching power supply and DC-DC applications, radio frequency applications, switching amplifier circuits and many other analog and power conversion circuits.The working principle of SRN3015-100M is relatively simple and straightforward. The core of the fixed inductor is air-core and is wound with two strands of insulated copper. This structure provides very low series resistance and very high self-inductance. The two parts of the windings are separated by an isolation layer, which provides additional isolation and improved performance. The two winds are then connected together at the two ends with the help of through-hole technology. Finally, the inductor is housed in an epoxy-coated metal shield, which provides excellent protection to the inductor.The main features of SRN3015-100M are its low DC resistance (DCR) and high quality factor (Q). The DCR is extremely low and can be as low as 0.05 ohms. This low resistance helps to keep the circuit power loss as low as possible ensuring high efficiency. Furthermore, the fixed inductor has a very high Q-factor which is mainly affected by the number of turns, the core and the shield. The higher the number of turns, the higher the Q-factor and the better the inductance stability in the circuit. The core material and shield also play a role in the inductor’s quality factor and will significantly affect the overall performance of the circuit.SRN3015-100M fixed inductor is utilized in many analog and power conversion circuits, especially in switching power supply and DC-DC applications. It can be used in many circuits for filtering, choosing frequency, coupling, decoupling and impedance matching. Therefore, it provides highly efficient solutions for power conversion and delivers excellent performance in low-power applications. The fixed inductor is also highly efficient for high-frequency signals, which allow for the transfer of more power with less power loss.In conclusion, SRN3015-100M fixed inductor provides excellent performance in a variety of applications, from filtering, coupling, decoupling to power conversion. Its low DC resistance and high quality factor offers superior performance in low-power applications, as well as high-frequency signals. It provides highly efficient and cost effective solutions for a wide range of analog and power conversion circuits. Therefore, SRN3015-100M fixed inductor is very popular in many industries.
