If you’re in the market for a reliable, cost-effective fixed inductor with an even distribution of inductance and a compact form factor, you’ll be pleased with the performance of the PL8509 series of fixed inductors. These inductors, developed by Pulse Electronics, provide the excellent power inductance and stability that require minimal physical space while still delivering results at a remarkably low cost.This series of fixed inductors is particularly well-suited to both commercial and industrial applications, such as switching regulators, resonant circuit applications, and overvoltage protection. It’s also a functional option when used in parallel with transistors for improved power efficiency.As far as construction is concerned, the PL8509 series is a high-permeability material ranging in value from 2.2uH to 47uH and can handle up to 1.5A in direct current. It also boasts low dc resistance when compared to other inductor models, meaning that it’s an ideal choice for users who need to transfer a high level of power while conserving energy.In terms of working principles, the PL8509 series of fixed inductors utilize the basic premise of inductance to transfer and limit the flow of electricity. Specifically, a fixed inductor generates an electromagnetic field around it when exposed to a varying current as it passes through the core of the device. As the current increases, the magnetic field generated by the current in the coil also increases. This effect is called inductance and is monitored and measured in henry units.The resulting ability of the PL8509 series to store energy is what makes it a reliable choice for applications that need to protect and transfer a steady and controlled flow of current, including motor control, digital isolators, and voltage regulators.In terms of their form factor, the PL8509 series of fixed inductors are available in three separate sizes—0603, 0805, and 1206. In any of these form factors, users will find a reliable and cost-effective inductor that can handle a range of power needs, typically between 150mA and 1.5A, while also providing outstanding durability and resistive performance.Performance-wise, the PL8509 series can handle temperatures ranging from -55°C to +125°C, and the inductance response curve remains steady and reliable regardless of the temperature fluctuations. This ensures that users will get the same reliable performance for years to come.All in all, the PL8509 series of fixed inductors is a reliable, cost-effective option for users who need to protect and transfer a steady and controlled current. Its high permeability materials, efficient form factor, excellent performance, and durability make it the optimal solution for commercial and industrial applications. Whether you need to protect against overvoltage, use it for digital isolators, or for motor control, the PL8509 series is a trustworthy product that will get the job done right.
