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

Typical Applications & Why This Part Fits

• RF Tuning Circuits: The ±1% ultra-tight tolerance and C0G/NP0 stability ensure precise frequency control in oscillators and filters, minimizing signal distortion.
• Sensor Reference Capacitors: 50V voltage rating provides ample headroom for industrial sensor interfaces, while the 330pF value suits capacitive sensing reference paths.
• High-Speed Digital Decoupling: The 0402 footprint saves PCB space near processor pins, and the stable NP0 dielectric guarantees consistent decoupling performance across -55°C to +125°C.

Key Features & Advantages

• ±1% Tight Tolerance: Enables high-accuracy circuit designs without the need for additional trimming or calibration.
• C0G/NP0 Dielectric: Virtually no capacitance change with temperature or voltage, ideal for frequency-critical designs.
• Compact 0402 Case Size: Reduces board footprint by up to 50% compared to 0603, enabling denser layouts in handheld and IoT modules.

Frequently Asked Questions

1. Q: What makes GRM1555C1H331FA01J different from a standard X7R capacitor?
