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

Typical Applications & Why This Part Fits

• RF Impedance Matching: The ±0.05pF tolerance ensures negligible deviation from target inductance in antenna or filter matching networks, critical for 2.4 GHz and 5 GHz bands.
• High-Frequency Decoupling: C0G/NP0 provides flat capacitance over temperature and frequency, making this 4.3pF MLCC ideal for VCO or PLL supply noise filtering.
• Timing Circuits: In precision oscillators or timer ICs, the 4.3pF value with 50V rating and minimal drift delivers consistent pulse generation in compact 0402 format.

Key Features & Advantages

• Ultra-Tight Tolerance (±0.05pF): Enables repeatable performance in resonant circuits without manual tuning, reducing production cost.
• C0G/NP0 Dielectric: Offers near-zero capacitance change from -55°C to +125°C, ensuring stable operation in variable thermal environments.
• 40 V margin – 50V Rating: Provides ample headroom for 3.3V/5V logic rails, enhancing long-term reliability under voltage spikes.
• 0402 Miniature Footprint: Saves PCB real estate while maintaining high self-resonant frequency, perfect for dense IoT modules.
