MLCC GRM21A5C2E120JW01D

What is GRM21A5C2E120JW01D MLCC?

The GRM21A5C2E120JW01D is a Class 1 SMD capacitor manufactured by Murata (村田). Key specs include 12pF capacitance, 250V rated voltage, C0G/NP0 dielectric, and ±5% tolerance. RoHS compliant, it is designed for high-voltage decoupling and timing circuits where low drift and high stability are critical.

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

Typical Applications & Why This Part Fits

• Power Supply Filtering: The 250V rating handles line transients in DC-DC converters and PoE circuits, while the 0805 package saves board space.
• RF/Timing Circuits: C0G/NP0 dielectric provides ultra-low capacitance drift over temperature and voltage, ensuring accurate resonance and timing in oscillator tanks.
• Signal Coupling in High-Voltage Interfaces: 12pF value is ideal for AC coupling in CAN bus or sensor interfaces, with ±5% tolerance maintaining signal integrity.

Key Features & Advantages

• High Voltage in Compact Footprint: 250V rating in an 0805 case reduces component count in space-constrained designs.
• Class 1 Dielectric Stability: C0G/NP0 ensures capacitance change < ±30ppm/°C, ideal for precision applications.
• Low ESR/ESL: Murata’s multilayer construction offers low equivalent series resistance for efficient high-frequency decoupling.

Frequently Asked Questions

1. Q: What makes GRM21A5C2E120JW01D different from a standard X7R MLCC?
   A: It uses a C0G/NP0 dielectric, which provides near-zero capacitance variation with temperature and voltage, unlike X7R which can change by ±15%.
2. Q: Is GRM21A5C2E120JW01D 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 this 0805 capacitor.
