Schurter FMBB EP Single-Phase EMC Block Filters are ultra-compact filters with high-performing attenuation. Schurter FMBB EP Filters are two-stage filters that are more powerful than typical filters. This performance allows FMBB EPP to meet the space constraints and performance requirements of state-of-the-art electronic devices. These filters provide exceptional common-mode attenuation at low frequency and common-mode and differential-mode attenuation over a wide frequency range, allowing the series to provide excellent broadband attenuation. FMBB EP is ideal for use in applications confronted with the most stubborn electromagnetic interference (EMI), such as any equipment with extremely fast semiconductor processing speeds at high switching frequencies.
