What is GJM1555C1HR50RB12D MLCC?
The GJM1555C1HR50RB12D is an SMD Capacitor manufactured by Murata (村田). Key specs include 0.5PF capacitance, 50V rating, C0G/NP0 dielectric, and ±0.03pF tolerance. RoHS compliant, it is designed for high-frequency precision and stable performance in compact circuits.
✔ RoHS Compliant / ✔ 0402 / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Matching Networks: The ultra-low 0.5pF capacitance and ±0.03pF tight tolerance ensure accurate impedance matching in 50Ω transmission lines for wireless modules.
- High-Speed Signal Coupling: C0G/NP0 dielectric provides near-zero capacitance drift with temperature and voltage, essential for preserving signal integrity in high-speed data interfaces.
- VCO & PLL Loop Filters: The 0402 package saves board space while the 50V rating handles voltage swings in oscillator tuning circuits without derating concerns.
Key Features & Advantages
- Tight Tolerance (±0.03pF): Enables repeatable circuit performance without manual tuning, reducing production calibration time.
- Stable C0G/NP0 Dielectric: Offers ±30ppm/°C temperature coefficient, ensuring capacitance remains constant across -55°C to +125°C environments.
- Compact 0402 Footprint: Ideal for miniaturized designs where board space is critical, such as IoT sensors or wearable devices.
