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

Typical Applications & Why This Part Fits

• High-Frequency RF Circuits: The tight ±1% tolerance and C0G/NP0 dielectric ensure stable capacitance from -55°C to +125°C, critical for impedance matching in Bluetooth and Wi-Fi modules.
• Timing/OSC Bypass: 820pF at 50V provides low ESR and ultra-low leakage, making it ideal for crystal oscillator load capacitors where drift must be under 0.1%.
• Automotive Sensor Signal Conditioning: The robust 50V rating and small 0402 footprint suit noise decoupling in engine control units where board space is limited.

Key Features & Advantages

• Precision Tolerance: ±1% capacitance accuracy enables consistent circuit behavior without manual tuning, cutting production calibration time.
• C0G/NP0 Stability: Zero voltage coefficient and flat temperature response (±30ppm/°C) eliminate derating issues across operating conditions.
• Compact 0402 Size: Reduces PCB footprint by 60% compared to 0603 MLCCs, supporting dense layout in wearable IoT designs.
