Typical Applications & Why This Part Fits

• RF Matching Networks: The ultra-low capacitance value (3.2 pF) and tight ±0.05 pF tolerance ensure precise impedance matching in 2.4 GHz and 5 GHz wireless modules, minimizing signal reflection.
• VCO & PLL Loop Filters: C0G/NP0 dielectric provides near-zero voltage and temperature coefficient, making this capacitor ideal for maintaining stable oscillator frequency under varying bias conditions.
• High-Speed Digital Decoupling: The 0402 package combined with 50V rating allows dense PCB layouts near high-speed ICs, delivering clean power supply rejection without parasitic resonance.

Key Features & Advantages

• Ultra-Stable C0G Dielectric: Capacitance change is less than ±30 ppm/°C over the operating range, ensuring predictable RF performance across temperature extremes.
• Low Equivalent Series Resistance (ESR): Murata’s advanced thin-film electrode technology achieves exceptionally low ESR, reducing heat generation and insertion loss in RF paths.
• Tight ±0.05 pF Tolerance: Enables fewer calibration iterations during production, cutting test time and cost in high-volume wireless devices.
