What is GRM21A5C2E221JW01D MLCC?
The GRM21A5C2E221JW01D is a SMD capacitor manufactured by Murata. Key specs include 220pF capacitance, 250V voltage rating, C0G/NP0 dielectric, and ±5% tolerance. RoHS compliant, it is designed for high-stability filtering and decoupling in compact circuits.
✔ RoHS Compliant / ✔ 0805 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- High-voltage DC-DC converters: The 250V rating and C0G/NP0 temperature stability ensure reliable input/output filtering under voltage stress.
- RF & communication modules: ±5% tolerance and low loss C0G dielectric maintain precise impedance matching in oscillator and PLL circuits.
- Automotive sensor interfaces: Stable capacitance over temperature (C0G/NP0) makes it ideal for harsh environment sensing and protection circuits.
Key Features & Advantages
- High voltage in compact 0805 case: 250V rating in a standard 0805 footprint saves board space while handling elevated potentials.
- Ultra-stable C0G/NP0 dielectric: Near-zero capacitance change with temperature and voltage, critical for timing and precision analog circuits.
- Tight ±5% tolerance: Reduces design margin overhead, enabling consistent performance across production batches.
Frequently Asked Questions
- Q: What makes GRM21A5C2E221JW01D different from a standard X7R MLCC?
A: Its C0G/NP0 dielectric provides far better temperature stability (±30ppm/°C) and no DC bias degradation, unlike X7R which can lose 30–50% capacitance under rated voltage. - Q: Is GRM21A5C2E221JW01D RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free. - 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 urgent development needs.
