✔ RoHS Compliant  /  ✔ 0402  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• RF Tuning & Impedance Matching: The ±2% tight tolerance and C0G/NP0 stability ensure minimal drift in resonant circuits, making this 12PF capacitor ideal for wireless modules and filters.
• Timing & Oscillator Circuits: 50V rating and low capacitance variation over temperature (C0G) guarantee reliable oscillation in MCU clock lines and PLLs.
• High-Q, Low-Loss Decoupling: The 0402 footprint combined with NP0 dielectric enables ultra-low ESR bypassing in high-speed data converters and RF amplifiers.

Key Features & Advantages

• ±2% Capacitance Tolerance: Reduces design margin requirements and improves yield in precision analog and RF applications.
• C0G/NP0 Dielectric: Excellent temperature stability (±30ppm/°C) and negligible voltage coefficient, maintaining 12PF across operating conditions.
• 50V Rated Voltage: Provides headroom for power rail decoupling and signal coupling in 3.3V to 12V systems without derating concerns.
