Typical Applications & Why This Part Fits

• RF Tuning & Matching Networks: The tight ±5% tolerance and C0G/NP0 characteristic ensure stable, predictable performance in impedance matching circuits for wireless modules operating at 250V peak levels.
• DC-DC Converter Snubbers: 250V voltage rating and low ESR/ESL of the 0805 body allow this 47pF cap to handle high-frequency ringing suppression in power supply designs without derating concerns.
• Timing & Oscillator Circuits: C0G/NP0 dielectric provides near-zero capacitance change over temperature and DC bias, preserving the accuracy of RC timing constants in industrial control loops.

Key Features & Advantages

• Ultra-Stable C0G/NP0 Dielectric: Capacitance variation is less than ±30ppm/°C, ensuring consistent filtering and timing across -55°C to +125°C operating range.
• High Voltage Rating in Compact 0805: 250V capability in a small footprint reduces board space while meeting isolation requirements for PoE and battery management systems.
• Murata Quality & Long-Term Reliability: Murata’s rigorous manufacturing processes guarantee low failure rates and excellent soldering performance for automated assembly.

Frequently Asked Questions

1. Q: What makes GRM21A5C2E470JW01D different from a standard X7R capacitor?
   A: Unlike X7R, the C0G/NP0 dielectric in this 47pF 250V MLCC exhibits virtually no capacitance change under DC bias or temperature variation, making it ideal for precision analog and RF circuits where stability is critical.
2. Q: Is GRM21A5C2E470JW01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, fully compatible with lead-free soldering profiles.
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 for the GRM21A5C2E470JW01D. Flexible quantities are available to match your design phase needs.
