The MAX7427EUA+ is an high-performance, electric-field interference (EFI) filter module. This ultra-compact active filter is designed for use in EFI and signal integrity applications, such as power supply, Pulse Width Modulation (PWM), PLC, motor control, disconnect switches, etc. It can filter out higher-order harmonics to reduce electrical noise, and is suitable for a wide range of applications.

MAX7427EUA+ Application Field

The MAX7427EUA+ active filter module is designed to reduce the high-order harmonics of power electronic devices. The device is ideal for applications such as power supply, Pulse Width Modulation (PWM), PLC, motor control, disconnect switches, etc. This product has an integrated 3-wire EMI filter, eliminating the need for an external filter.

The MAX7427EUA+ is a low-power solution, consuming only 0.26W during operation, thus ensuring efficient energy savings and making it suitable for applications that require low power consumption. The device is available in the industry-standard 3-pin package, and can be easily integrated into existing circuitry.

MAX7427EUA+ Working Principle

The MAX7427EUA+ active filter module works by using high-performance filter elements to lower higher-order harmonics and improve signal integrity. The filter elements are designed to provide an impedance of up to 45 ohms over the wide frequency range from dc to 1GHz. This will ensure high-performance filtering while consuming very little power.

The MAX7427EUA+ active filter module also features an integrated EMI shield. This shield can block up to 20 dB of interference and ensures that the signal is preserved even in noisy environments. The module is also equipped with an over-voltage protection that can withstand up to 6V static spikes.

The MAX7427EUA+ active filter module is RoHs-compliant, making it suitable for use in green-friendly applications. The device is also offered with a wide range of temperature qualifications and can safely operate at temperatures from -40°C to 125°C.

In addition to its high-performance features, the MAX7427EUA+ also offers a wide range of certification and safety approvals. It is UL, cUL, and CE-approved, and is certified to meet the safety requirements of IEC60730-2-14, CSA C22.2, and EN 609501-1. This ensures that the device meets the highest industry standards of quality and performance.
