PEMI1QFN/RE,315 Filters

EMI/RFI filters are active or passive electronic filters designed to suppress electrical noise, such as conducted emissions or radiated emissions, from the power and/or sensor lines of an electrical device or system. They protect against interference from the outside environment, ensuring a reliable, safe, and technically correct operation for the device or system. There are several types of EMI/RFI filters, including LC, RC networks, and the PEMI1QFN/RE,315.

The PEMI1QFN/RE,315 is a fixed-frequency, wall-mounted, single-stage EMI/RFI filter. The filter utilizes a snap-on connection and features a carbon-loaded capacitance/resistance design and a built-in safety switch. Its frequency range is 65 kHz to 6 GHz, making it suitable for a wide range of applications. With its small footprint and lightweight design, the PEMI1QFN/RE,315 is also easy to install in a variety of locations.

The PEMI1QFN/RE,315 is commonly used in industrial applications that require the filtering of noise from power and/or sensor lines. It is especially suited for medium-sized installations, such as those found in food and beverage production facilities, process control systems, and machinery control systems. The filter is well-suited for both radiated and conducted noise suppression, and also features automatic overvoltage protection.

The working principle of the PEMI1QFN/RE,315 is based on capacitive filtering. The filter consists of ceramic discs containing a specific amount of charge, which are connected to the power line. As signals travel through the filter, the charge stored in the ceramic discs powers up and generates a sharp return signal that suppresses noise. The filter also utilizes an inductor, which reduces the impedance of the simultaneous positive and negative power lines, ensuring a smoother, more reliable signal.

The PEMI1QFN/RE,315 is an effective way to reduce the amount of electrical noise present in industrial applications. The filter’s small footprint and lightweight design make it ideal for a wide range of applications, and its capacitive filtering method ensures reliable and efficient noise suppression.
