What is GJM1555C1HR25RB12D MLCC?
The GJM1555C1HR25RB12D is a high-frequency SMD capacitor manufactured by Murata. Key specs include 0.25pF capacitance, 50V rating, C0G/NP0 dielectric, and ±0.03pF tolerance. RoHS compliant, it is designed for precise RF impedance matching and stable timing circuits.
✔ RoHS Compliant / ✔ 0402 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Antenna Tuning: The ultra-low 0.25pF capacitance enables fine parasitic adjustment in 2.4GHz and 5GHz bands without shifting center frequency excessively.
- High-Frequency Filter Networks: The C0G/NP0 dielectric ensures <0.3% capacitance drift over -55°C to +125°C, critical for band-pass filter stability.
- VCO and PLL Loop Filters: The tight ±0.03pF tolerance minimizes phase noise variation in voltage-controlled oscillators operating at 50V bias.
Key Features & Advantages
- Ultra-Strict Tolerance (±0.03pF): Enables repeatable RF performance across production batches, reducing tuning effort in volume assembly.
- 50V Voltage Rating: Provides ample headroom for GaAs and GaN power amplifier bias circuits while maintaining 0402 footprint.
- Low ESR at GHz Frequencies: The C0G/NP0 construction delivers Q factor >1000 at 1GHz, minimizing insertion loss in signal paths.
Frequently Asked Questions
- Q: What makes GJM1555C1HR25RB12D different from a standard 0402 capacitor?
A: Its 0.25pF value paired with ±0.03pF tolerance is rare—standard parts typically offer ±0.05pF, making this suitable for sub-pF precision RF tuning. - Q: Is GJM1555C1HR25RB12D RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, meeting EU directive requirements. - 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 design verification.
