Resonators

Definition: A resonator is a passive electronic component that exhibits resonance at a specific frequency, commonly used for frequency stabilization in oscillators and timing circuits.

Types:

• Ceramic Resonators
• Crystal Resonators (e.g., Quartz)
• SAW Resonators (Surface Acoustic Wave)
• LC Resonators (Inductor-Capacitor based)

Applications:

• Clock generation in microcontrollers
• RF filters and matching networks
• Timing references in communication systems

Key Parameters:

• Resonant Frequency (Hz)
• Q Factor (Quality Factor)
• ESR (Equivalent Series Resistance)
• Load Capacitance (for crystals)
• Temperature Stability (ppm/°C)

Note: Crystal resonators offer higher precision and stability than ceramic resonators but are more expensive and fragile.
