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

Typical Applications & Why This Part Fits

• High-Voltage Snubber Circuits: The 1kV rating and C0G/NP0 dielectric provide low loss and minimal capacitance change under DC bias, ideal for suppressing voltage spikes in power supplies.
• DC-DC Converter Output Filtering: 100pF with ±5% tolerance ensures precise filtering of high-frequency noise, while the 1206 package withstands the thermal stress of compact converters.
• RF Coupling & Decoupling: C0G/NP0 offers excellent frequency stability, making this MLCC suitable for RF paths where consistent low ESR is critical at 1kV.

Key Features & Advantages

• High Voltage Capability (1kV): Enables use in industrial and automotive subsystems without derating concerns, even in 480VAC environments.
• C0G/NP0 Dielectric: Near-zero temperature coefficient (±30ppm/°C) guarantees capacitance remains stable from -55°C to +125°C, vital for timing and precision circuits.
• 1206 Surface-Mount Package: Standard footprint supports automated assembly and offers good power dissipation, balancing size and performance for high-voltage designs.

Frequently Asked Questions

1. Q: What makes GRM31A5C3A101JW01D different from a standard 100pF MLCC?
   A: This Murata part combines a 1kV rating with C0G/NP0 dielectric, whereas standard 100pF capacitors typically have lower voltage ratings (e.g., 50V or 100V) and may use X7R. The ±5% tolerance further ensures tight accuracy for high-reliability needs.
2. Q: Is GRM31A5C3A101JW01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, meeting EU environmental directives.
3. Q: What is the MOQ? Can we get small batches?
   A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply. Flexible quantities are available to match your project phase.
