MLCC GRM31A5C2J101FW01D

What is GRM31A5C2J101FW01D MLCC?

The GRM31A5C2J101FW01D is a high-voltage SMD capacitor manufactured by Murata. Key specs include 100pF capacitance, 630V rated voltage, C0G/NP0 dielectric, and ±1% tolerance in a 1206 package. RoHS compliant, it is designed for precision high-voltage circuits requiring stable capacitance over temperature and bias.

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

Typical Applications & Why This Part Fits

• High-Voltage DC-DC Converters: The 630V rating provides ample margin for snubber and filter networks in flyback and boost converters, while the C0G dielectric minimizes capacitance loss under voltage.
• Precision Timing & Oscillator Circuits: ±1% tolerance and a <±30ppm/°C temperature coefficient ensure consistent frequency stability in crystal oscillator load capacitors and PLL filter paths.
• Industrial Sensor Interfaces: 100pF small capacitance effectively couples high-frequency signals while blocking DC bias, and the 1206 package supports reliable soldering in automated assembly lines.

Key Features & Advantages

• 630V High Voltage Rating: Delivers robust headroom for transient spikes and continuous operation in 48V or higher rail systems.
• C0G/NP0 Dielectric: Nearly zero capacitance shift with temperature and voltage, enabling repeatable performance in analog and RF circuits.
• ±1% Tight Tolerance: Reduces design margin requirements and improves yield in impedance-sensitive networks.
