What is GRM1887U1A303JA01J MLCC?
The GRM1887U1A303JA01J is a multilayer ceramic capacitor (MLCC) manufactured by Murata. Key specs include 30000pF capacitance, 10V rated voltage, U2J dielectric, and ±5% tolerance. RoHS compliant, it is designed for stable, low-loss coupling and decoupling in space-constrained circuits.
✔ RoHS Compliant / ✔ 0603 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- High-frequency RF modules: U2J dielectric offers extremely low capacitance change over temperature and voltage, preserving signal integrity in 30000pF filter stages.
- Timing and oscillator circuits: The ±5% tolerance ensures tight control of RC time constants, while the 10V rating comfortably covers 3.3V or 5V logic rails.
- Ultra-compact IoT designs: The 0603 package saves board space, and the 30000pF value supplies adequate bypass capacitance for low-power wireless sensors.
Key Features & Advantages
- Stable U2J dielectric: Capacitance varies less than ±0.3% per volt and < ±1% from -55 to +125°C, outperforming X7R in precision applications.
- Lead-free & halogen-free: Fully RoHS compliant and compatible with RoHS manufacturing processes, meeting environmental standards.
- Small 0603 footprint: Fits dense PCB layouts while delivering 30000pF, reducing component height and enabling slimmer product designs.
Frequently Asked Questions
- Q: What makes GRM1887U1A303JA01J different from a standard X7R capacitor?
A: X7R changes capacitance dramatically under DC bias and temperature, whereas U2J maintains near-constant value: ideal for timing and filter circuits requiring 30000pF accuracy. - Q: Is GRM1887U1A303JA01J 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.
