PM638S-330-RC

Fixed Inductors

Fixed inductors are electronic components composed of basic inductors and some additional elements, usually used for resonant circuit applications. As their name suggests, they are fixed, meaning they cannot be adjusted or re-tuned. They are most commonly used in applications involving power conversion, such as power supplies, power converters, and inverters. They are also used in many signal processing and communication systems to add frequency-selective filtering or signal shaping.

PM638S-330-RC Application Field and Working Principle

The PM638S-330-RC is a fixed inductor, designed for use in switching power supplies. It is composed of a core and a coil wrapped around it with a ferrite magnetic material. This core material has a high saturation flux density, which allows for higher current handling and low losses at high frequencies. The primary function of the PM638S-330-RC is to store energy during high-frequency operation. This is done by creating a magnetic field around the core. As current is passed through the inductor, a magnetic field is created, which stores the energy until the current is removed.

The PM638S-330-RC is designed for use in low power applications. This inductor is typically used in switching power converters operating at frequencies above 100 kHz. It is also suitable for use in communication systems, such as Wi-Fi and 3G/4G/5G networks. Additionally, it can be used in low noise signal processing applications, such as analog-to-digital converters.

The PM638S-330-RC is constructed using either surface mount or through-hole construction techniques. The body of the inductor is made from molded thermoplastic, while the lead wires/pins are made from copper/nickel plated steel alloy. It features a low DC resistance and is designed to generate minimal noise or EMI. It is rated for operation up to 1 MHz, with an operating temperature range of -40 to 85ºC.

In summary, the PM638S-330-RC is a fixed inductor designed for use in switching power supplies and other related applications. It features a high saturation flux density along with a low DC resistance. Additionally, it can be used in communication systems, signal processing applications, and other related applications.
