EMI/RFI filters are critical components in electronic systems, allowing the effective regulation of Electric and Magnetic interference, as well as providing a safe usage environment. The PEMI2STD/LT, 115 digital filter is a device specifically designed for applications which require higher stability and off-line isolation performance than is achievable with standard designs. Its increased performance capability is provided by the use of advanced circuitry which includes blocking capacitors, high-frequency inductors, and two resonant circuits. The device is capable of operating over a wide temperature range of -40 to +125 degrees Celsius, making it suitable for diverse applications.

The application field of the PEMI2STD/LT, 115 is broad, ranging from consumer electronics, smart homes, medical equipment, automotive components, telecommunications, and industrial control products. It can also be applied to a range of high voltage applications, such as those involving motors, variable frequency drives, aircraft, and light-rail power sources. In all of these applications, the filter provides a crucial layer of protection against electromagnetic interference, which can distort or damage circuitry.

The working principle of the PEMI2STD/LT, 115 relies on the use of several key components. To begin with, blocking capacitors are typically used to filter out high frequency components, such as those which are present in switching power supplies, and to act as a first line of defence against EMI. These are connected in series between the input and output of the filter, and present a low impedance path which is designed to effectively shield the devices behind it. Additionally, the use of high-frequency inductors improves the filter’s overall performance by reducing the amount of noise that is generated by the switching power supplies.

A key feature of the PEMI2STD/LT, 115 EMI/RFI filter is its two resonant circuits. The first uses the filter’s blocking capacitors to create an AC electrical circuit that has a specific resonance frequency. This frequency, typically in the range of 1 kHz to 10 kHz, is designed to reject any incoming radiation which is present in the same frequency range. The second resonant circuit operates at a much higher frequency, and is designed to reject any incoming radiation which is present in the range of 10 MHz to 18 GHz. Together, these two resonant circuits give the PEMI2STD/LT, 115 an incredibly wide frequency response, ensuring that even the most modern interference sources can be blocked effectively.

In summary, the PEMI2STD/LT, 115 digital filter is an ideal solution for a range of high voltage applications which require reliable EMI/RFI protection. Its advanced circuitry combines blocking capacitors, high-frequency inductors, and two resonant circuits to provide superior noise reduction and off-line isolation performance, whilst also being capable of operating over a wide temperature range. As such, the device is a prominent choice for a number of diverse application fields, from consumer electronics to industrial control systems.
