What is GRM42A7U3F101JW31L MLCC?
The GRM42A7U3F101JW31L is a multi-layer ceramic capacitor (MLCC) manufactured by Murata. Key specs include 100pF capacitance, 3.15kV rated voltage, U2J dielectric, 1808 package size, and ±5% tolerance. RoHS compliant, it is designed for high-voltage stability and low drift in demanding environments.
✔ RoHS Compliant / ✔ SMD / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- High-Voltage Snubber Circuits: The 3.15kV rating and U2J dielectric ensure reliable transient suppression without capacitance loss under DC bias.
- DC-DC Converter Feedback Networks: The 100pF ±5% tolerance provides precise frequency compensation, while U2J stability minimizes drift across temperature.
- Medical Imaging Power Supplies: The compact 1808 footprint saves board space, yet the 3.15kV withstand voltage meets safety isolation requirements.
Key Features & Advantages
- Ultra-High Voltage Rating: 3.15kV in a small 1808 package eliminates need for larger, more expensive solutions in high-density power modules.
- U2J Dielectric Stability: Near-linear temperature coefficient (±30ppm/°C) and negligible voltage coefficient ensure consistent performance for timing and filtering.
- Tight ±5% Tolerance: Enables accurate matching in resonant circuits and reduces calibration overhead for precision equipment.
