MLCC GRM21A5C2E220JW01D

What is GRM21A5C2E220JW01D MLCC?

The GRM21A5C2E220JW01D is an SMD multilayer ceramic capacitor manufactured by Murata. Key specs include 22pF capacitance, 250V DC rating, C0G/NP0 dielectric, 0805 package, and ±5% tolerance. RoHS compliant, it is designed for high‑voltage, precision filtering where stable performance over temperature is critical.

✔ RoHS Compliant  /  ✔ 0805  /  ✔ MuRata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• High‑Voltage DC‑DC Converters: The 250V rating ensures reliable decoupling and snubbing in power stages where standard low‑voltage MLCCs would fail.
• RF Tuning & Matching Networks: C0G/NP0 dielectric provides virtually zero capacitance change with voltage and temperature, preserving resonance in VCOs and filters.
• Precision Timing Circuits: ±5% tolerance and excellent aging characteristics make it ideal for RC oscillators and delay lines that demand consistent 22pF value.

Key Features & Advantages

• High Voltage Rating (250V): Enables use in 48V bus, PoE, and industrial control circuits without derating concerns.
• Tight ±5% Tolerance: Reduces design margin waste, allowing more compact PCB layouts and fewer tuning steps in production.
• C0G/NP0 Dielectric: Ultra‑stable capacitance over –55°C to +125°C (< ±30 ppm/°C), eliminating temperature‑induced drift in sensitive analog paths.

Frequently Asked Questions

1. Q: What makes GRM21A5C2E220JW01D different from a standard 22pF MLCC?
   A: Its 250V voltage rating and strict C0G dielectric set it apart; most 22pF 0805 parts are rated only 50V or 100V and use X7R, which drifts with voltage.
2. Q: Is GRM21A5C2E220JW01D 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 for engineering samples.
