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

Typical Applications & Why This Part Fits

• RF Impedance Matching: The tight ±0.05pF tolerance ensures minimal deviation in matching networks for Bluetooth and Wi-Fi modules, preserving signal integrity.
• High-Frequency Bypass: C0G/NP0 dielectric offers low ESR and stable capacitance up to 50V, ideal for decoupling in oscillator and PLL circuits.
• Precision Timing: Excellent temperature stability (ΔC ±30ppm/°C) makes this capacitor suitable for timing and filter circuits in IoT sensor nodes.

Key Features & Advantages

• Ultra-Tight Tolerance: ±0.05pF enables accurate capacitance in sensitive RF and analog circuits where standard ±0.1pF or ±0.25pF devices fall short.
• Low Voltage Coefficient: C0G/NP0 material maintains constant capacitance regardless of applied DC bias, critical for voltage-controlled oscillators.
• Compact 0402 Footprint: The miniature size supports high-density PCB layouts in portable and space-constrained designs.

Frequently Asked Questions
