Fixed Inductors are used in various electronic circuits for a range of applications. The PM75-181K-RC is one such inductor with a variety of uses, from filtering and functions in RF (Radio Frequency) signal paths to high-voltage applications such as high-voltage generator coils. The PM75-181K-RC has a wide frequency range from 500kHz to 1 GHz. This makes it suitable for medical, automotive, aviation, telecommunications, and industrial applications.

Application Field

The PM75-181K-RC is suitable for a range of applications. It is commonly used for providing impedance in RF signal paths, including low-noise amplifier (LNA) matching and DC blocking circuits. It is also used for oscillator circuits, mobile and radio communication base station amplifiers, and wireless receivers. In automotive applications, it is used for antenna matching, audio circuits, and electric motor coils. It is also used in medical and aviation applications for antenna tweeter matching, noise filters, and feeder lines. Additionally, the PM75-181K-RC is used for high voltage generator circuits, DC-DC converter circuits, and energy storage circuits, which require high-power handling and high-voltage withstand capability.

Working Principle

The PM75-181K-RC works by using the inductance of a coil to mitigate the impact of unwanted RF signals, to shape the signal as it passes through the inductor, and to block the passage of DC current. The coil is made of a special high temperature permalloy material which increases the inductance for a given size as well providing the robustness needed in high-voltage applications. It also helps to reduce parasitic effects, such as skin effect, which can cause signal distortion. Additionally, the core material and coil structure are designed to reduce off-chip parasitic elements, such as stray capacitances and inductances, which can also cause signal distortions.

The PM75-181K-RC is a surface mount component, and it comes in a wide variety of mounting options, including through-hole, surface mount, and SMD (Surface-Mount-Device). For medical, automotive, and industrial applications, the device is available in lead/lead-free, nickel-barrier, and halogen-free packages.

The PM75-181K-RC is an ideal inductor for high-voltage applications. It is robust and its small size allows it to be used in a wide range of devices. Its wide range of frequencies and low parasitic elements make it ideal for applications which require precise RF signal shaping over a wide frequency range.
