Product Overview
Features
- Special internal plate architecture with opposing current paths for ultra‑low equivalent series inductance (ESL)
- Manufactured using multilayer ceramic capacitor (MLCC) processes for consistent electrical performance
- Bypass filter design that routes only unwanted noise to ground, not signal current
- Single ceramic element integrates multiple capacitive functions
- Optimized for balanced and twin‑line circuit configurations
- Compatible with standard surface‑mount PCB assembly methods
Benefits
- Improves high‑frequency noise suppression compared to conventional discrete capacitors
- Maintains stable capacitance over temperature by integrating capacitors within one ceramic structure
- Eliminates current‑handling limitations associated with feedthrough devices
- Simplifies EMI filter design by reducing component count and layout complexity
- Enhances performance in real‑world applications when properly mounted and grounded
Target Applications
- Balanced or twisted‑pair signal lines
- Motor drive and motor control interfaces
- Amplifier input filtering
- Noise suppression on differential data or control lines
- EMI control in compact PCB designs without bulkhead filtering
