✔ RoHS Compliant / ✔ 0402 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- Wireless Communication Modules: The 9.4pF ±0.05pF tolerance ensures accurate impedance matching for Bluetooth/Wi‑Fi front‑ends, reducing signal reflection.
- VCO & PLL Oscillators: C0G/NP0 dielectric provides ultra‑stable capacitance over temperature and voltage, crucial for maintaining lock range and phase noise.
- High‑Speed Data Interfaces: 50V rating and small 0402 footprint enable AC‑coupling or DC‑blocking in SerDes lanes without compromising signal integrity.
Key Features & Advantages
- Extreme Capacitance Precision: ±0.05pF accuracy minimizes tuning effort in narrow‑band RF filters and matching networks.
- Class‑1 Dielectric Stability: C0G/NP0 exhibits capacitance change < ±30ppm/°C, ideal for temperature‑sensitive applications like GPS receivers.
- Compact 0402 Package: Saves board space in densely‑populated handheld or IoT designs while handling 50V without derating concerns.
Frequently Asked Questions
