SMD C Filters 1806J1000680MATE01
1806J1000680MATE01
SMD C Filters are 3‑terminal surface‑mount EMI filters that reduce conducted noise by shunting high‑frequency interference to ground while carrying the signal through internal electrodes.

Product Overview
Features
- 3‑terminal “C” filter construction with end‑to‑end short circuit and line‑to‑ground capacitance
- Manufactured using conventional MLCC processes (E01 / E07 / E17 series)
- Reduced internal inductance compared with standard 2‑terminal MLCCs
- Current‑carrying capability linked to electrode cross‑section and capacitance value
- Surface‑mount format compatible with standard PCB soldering methods
- Insertion loss characterized on controlled 50 Ω stripline test boards
Benefits
- Improves high‑frequency attenuation versus discrete 2‑terminal capacitors
- Enables more effective EMI suppression without increasing PCB footprint
- Supports predictable electrical performance when mounted per recommendations
- Simplifies signal‑line filtering by combining conduction and grounding in one device
- Allows design flexibility across signal and low‑current power lines
Target Applications
- Signal line EMI filtering on printed circuit boards
- Noise suppression for control, data, and sensor interfaces
- Filtering in compact electronics where panel‑mount solutions are not feasible
- Supplementary EMI control alongside shielding or partitioned PCB layouts
- High‑frequency noise reduction in mixed‑signal designs
