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

Typical Applications & Why This Part Fits

• High-Voltage DC-DC Converters: The 1KV rating and C0G/NP0 dielectric ensure minimal capacitance change under bias, making it ideal for snubber and coupling circuits in 400V-800V bus architectures.
• RF & Power Amplifier Matching: With 470pF and low ESR characteristics of C0G/NP0, this capacitor provides stable impedance matching up to several hundred MHz without microphonic noise.
• Industrial Sensor Interfaces: The ±5% tight tolerance and 1206 footprint simplify calibration in precision analog front-ends, while 1KV headroom adds margin against transient surges.

Key Features & Advantages

• High Voltage in Compact 1206: Delivers 1KV DC rating within a standard 1206 SMD body, reducing board space versus larger case sizes.
• C0G/NP0 Class 1 Dielectric: Offers near-zero capacitance drift over temperature (-55°C to +125°C) and voltage, ensuring consistent circuit behavior.
• ±5% Tolerance for Precision: Tight capacitance control enables accurate filtering and timing without trimming or additional compensation components.

Frequently Asked Questions

1. Q: What makes GRM31A5C3A471JWA1D different from a standard MLCC?
   A: This part combines a 1KV voltage rating with C0G/NP0 stability in a 1206 package, whereas standard MLCCs often use X7R/X5R dielectrics that lose capacitance under DC bias.
2. Q: Is GRM31A5C3A471JWA1D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
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 with flexible quantities.
