✔ RoHS Compliant  /  ✔ SMD  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Power Supply Output Filtering: The 100V rating and C0G/NP0 stability ensure accurate decoupling in high-voltage DC-DC converters, minimizing ripple without capacitance loss under bias.
• Automotive ECU Sensor Signal Conditioning: ±5% tolerance and low temperature drift of C0G make this capacitor ideal for precision analog circuits where capacitance stability is critical across temperature extremes.
• Industrial Control Interface Protection: The 1206 package provides robust mechanical strength for applications subject to vibration, while the 0.1µF value offers effective EMI suppression on control lines.

Key Features & Advantages

• High Voltage Rating (100V): Enables use in circuits with elevated operating voltages, reducing the need for series stacking and simplifying board layout.
• C0G/NP0 Dielectric: Ultra-stable capacitance over temperature (-55 to +125°C) and voltage, with negligible aging for long-term reliability.
• Compact 1206 Package: Balanced size for manual assembly and automated pick-and-place, supporting dense PCB designs without sacrificing performance.

Frequently Asked Questions

1. Q: What makes GRT31C5C2A104JA12L different from a standard X7R capacitor?
