✔ RoHS Compliant  /  ✔ SMD  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• High-Voltage DC-DC Converters: The 630V rating allows reliable decoupling in power stages where transients exceed standard 50V/100V parts, while the C0G dielectric ensures minimal capacitance drift under bias.
• RF Matching Networks: With a tight ±5% tolerance and ultra-stable C0G/NP0 temperature coefficient, this MLCC maintains precise impedance in antenna matching and oscillator circuits.
• Snubber Circuits for Switching Supplies: The 1206 body supports adequate creepage distance for high-voltage snubbing, and the low-loss ceramic reduces self-heating during repetitive pulses.

Key Features & Advantages

• C0G/NP0 Dielectric: Offers near-zero capacitance change with temperature and voltage, ensuring long-term circuit stability in precision analog designs.
• 630V High-Voltage Rating: Suitable for industrial power supplies, automotive battery management, and other applications requiring robust insulation margins.
• 1206 Standard Footprint: Balances power handling capability with board space efficiency, simplifying layout in compact high-density designs.
