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

Typical Applications & Why This Part Fits

• RF Matching Networks: The ultra-low 0.9pF value with ±0.05pF tolerance ensures accurate impedance matching in LNA and antenna circuits without detuning.
• High-Frequency Oscillators: C0G/NP0 dielectric provides negligible capacitance drift over temperature and voltage, critical for stable LC tank and Pierce oscillator designs.
• Filter Coupling & Bypass: At 50V rating this capacitor handles DC bias in front-end filters; the 0402 footprint fits densely packed LTE/5G modules.

Key Features & Advantages

• Extremely Tight Tolerance (±0.05pF): Enables repeatable circuit performance in production without recalibration, ideal for high-precision RF designs.
• Temperature-Stable C0G/NP0: Capacitance change ≤ ±30ppm/°C; no voltage derating effect, maintaining consistent response from -55°C to +125°C.
• Compact 0402 Size: Saves board space while supporting 50V operation; suitable for miniaturized IoT, wearable, and portable wireless devices.
