What is GJM1555C1H190FB01D MLCC?
The GJM1555C1H190FB01D is a high-precision SMD capacitor manufactured by Murata. Key specs include capacitance of 19 pF, rated voltage of 50 V DC, C0G dielectric, and a tight tolerance of ±1%. RoHS compliant, it is designed for high-frequency stability and minimal capacitance drift in critical signal paths.
✔ RoHS Compliant / ✔ 0402 Package / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Impedance Matching Networks: The 19 pF ±1% value and C0G temperature characteristics ensure predictable resonance behavior across 50 V operating conditions, ideal for precision RF stages in wireless modules.
- VCO & PLL Loop Filters: Minimal voltage coefficient and ultra-stable capacitance over temperature make this 0402 MLCC suitable for keeping phase noise low in oscillator circuits where 19 pF sets the center frequency.
- Sensor Signal Conditioning: The ±1% tolerance avoids gain errors in capacitive divider circuits, while the 0402 footprint saves space on densely populated IoT sensor boards.
Key Features & Advantages
- Strict ±1% Tolerance: Tight capacitance accuracy eliminates the need for manual trimming in production, reducing calibration time and improving first-pass yield.
- C0G Class I Dielectric: Near-zero capacitance change with temperature and voltage, ensuring consistent filter cutoff frequencies even under real-world supply variations.
- 50 V Rating in 0402: Higher voltage headroom than typical 25 V parts provides robust margin for power rail decoupling or DC-blocking without increasing board footprint.
Frequently Asked Questions
- Q: What makes GJM1555C1H190FB01D different from a standard 0402 capacitor?
A: This Murata GJM series part guarantees ±1% tolerance and C0G stability, whereas standard 0402 MLCCs typically offer only ±5% or ±10% with X7R dielectric, making it suitable for precision RF and timing applications. - Q: Is GJM1555C1H190FB01D RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, fully compatible with reflow soldering processes. - 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 and flexible quantities for the 19 pF 50 V C0G 0402 capacitor.
