Product Overview
Features
- Surface‑mount construction compatible with standard reflow soldering processes
- Low equivalent series inductance (ESL) compared with discrete capacitor solutions
- Available as 3‑terminal “C” filters, Pi‑configuration filters, and integrated X2Y components
- Uses stable ceramic dielectrics such as C0G/NP0 and X7R (no Z5U/Y5V)
- Broad capacitance and voltage ranges to support signal and power line filtering
- Designed for effective EMI attenuation across wide frequency ranges
Benefits
- Reduces conducted EMI on signal and power lines to help meet EMC regulatory requirements
- Saves PCB area by replacing multiple discrete components with a single device
- Improves high‑frequency noise suppression versus standard MLCC decoupling capacitors
- Simplifies manufacturing with standard pick‑and‑place and reflow assembly
- Supports consistent filtering performance over temperature, voltage, and time
Target Applications
- Signal line filtering on densely populated PCBs
- Power rail noise suppression in electronic modules
- EMI control for data, control, and sensor interfaces
- Filtering in applications where panel‑mount bulkheads are not available
- Supplementary filtering used alongside shielding measures
