FMAB NEO with overvoltage protection

SCHURTER expands the successful range of built-in filters for single-stage systems FMAB NEO with optionally available overvoltage protection (varistors). This is increasingly in demand, especially in regions with many thunderstorms. The single-stage filter series has a compact design with high performance at the same time.

Overvoltage pulses (e. g. lightning) often have a devastating effect on electronic circuits. This can range from malfunctions to complete destruction. In response to special customer requests, SCHURTER has therefore extended its popular and successful FMAB NEO filter family with varistor variants for surge protection. These variants are available on request. They have ENEC approvals for the entire current range as well as UL/CSA approvals from 1 A to 20 A.

The FMAB NEO filter family offers maximum flexibility with three different filter designs (N, P and Q). Design N has two large X-capacitors for particularly high symmetrical attenuation in the lower frequency range; Design P has two standard X-capacitors for high symmetrical attenuation, while Design Q with a single X-capacitor provides good symmetrical attenuation. The entire filter family has an extended temperature range from -40 °C to +100 °C.

The single-stage filter series has steel housings with a closed bottom. This effectively shields the filter, no matter how it is installed. The series is suitable for applications with high symmetric interferences – such as devices with semiconductors that control large outputs (e.g. professional coffee machines, devices with hot water supply, industrial electronics). The particularly compact filters are also ideally suited for medical and household appliances.
