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

Typical Applications & Why This Part Fits

• RF Tuning & Matching Networks: The 0.3pF value with ±0.05pF tolerance enables precise impedance matching in GHz-band wireless modules without introducing parasitic capacitance.
• High-Frequency Filter Circuits: C0G/NP0 dielectric ensures near-zero capacitance shift over temperature and voltage, critical for LC filters in base stations or satellite receivers.
• Timing & Oscillator Circuits: The 50V rating and ultra-low capacitance help maintain clean signal integrity in crystal oscillator load capacitors and PLL loop filters.

Key Features & Advantages

• Ultra-Low Capacitance (0.3pF): Offers minimal parasitic coupling, ideal for very-high-frequency bypass and coupling where standard values are too large.
• Tight ±0.05pF Tolerance: Guarantees repeatable circuit performance without manual tweaking, reducing production calibration cost.
• High Stability C0G/NP0: ±30ppm/°C temperature coefficient and negligible aging effect ensure long-term reliability in precision analog/RF designs.
