Panel Mount EMI Filters
Panel mount EMI (electromagnetic interference) filters provide feedthrough low‑pass filtering at a shielded bulkhead to block conducted noise while passing power or signals through the panel.

Product Overview
Features
- Feedthrough panel-mount construction for shielded enclosures and bulkheads
- Uses stable ceramic dielectrics (X7R and C0G/NP0), avoiding Z5U/Y5V materials
- High-frequency filtering performance specified to greater than 10 GHz
- Broad electrical offering including high capacitance values and high working voltages
- Multiple mechanical styles including solder-in “pin-and-disc” formats and threaded bolt-in version
- Multiple circuit configurations available (e.g., C, L‑C, Pi, T
Target Applications
- Power and signal line feedthroughs on shielded equipment enclosures
- Filtering at I/O bulkheads for control lines, sensors, and mixed-signal interfaces
- EMI suppression at chassis entries for high-speed electronics and RF-adjacent systems
- Noise reduction for cables entering/exiting metal housings in harsh electrical environments
- Partition/wall filtering between screened compartments in modular equipment

Design Tools
- Helps maintain EMC (electromagnetic compatibility) by reducing conducted emissions and susceptibility at the enclosure interface
- Preserves shielding integrity by filtering at the wall of the “Faraday cage,” not inside the box
- Delivers more consistent filtering over temperature and voltage than general-purpose ceramic dielectrics
- Supports compact, serviceable designs with multiple mounting styles for space and assembly constraints
- Enables higher-frequency noise attenuation without relying solely on additional shielding measures
- Simplifies filter selection with configuration options that match different source/load impedance conditions
