MLCC GJM1555C1H120JB01D

What is GJM1555C1H120JB01D MLCC?

The GJM1555C1H120JB01D is a precision SMD capacitor from Murata. Key specs include 12 pF capacitance, 50 VDC rating, C0G/NP0 dielectric, and ±5% tolerance in a 0402 package. RoHS compliant, it is designed for high-frequency stability and minimal drift over temperature.

✔ RoHS Compliant  /  ✔ 0402 Package  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• RF Tuning & Impedance Matching: The 12 pF ±5% value and C0G/NP0 dielectric ensure precise, temperature-stable capacitance for RF circuits, oscillators, and filters where frequency drift must be minimized.
• High-Speed Digital Decoupling: The 50 V rating and tight tolerance allow reliable decoupling in FPGA, DSP, and high-speed ADC/DAC power rails, suppressing noise without significant capacitance variation.
• Sensor Interface & Timing Circuits: Low loss and ultra-stable C0G/NP0 characteristics make this capacitor ideal for timing capacitors in crystal oscillator load circuits and precision analog sensor front-ends.

Key Features & Advantages

• Ultra-Stable C0G/NP0 Dielectric: Capacitance variation is minimal across temperature (-55°C to +125°C), providing consistent performance in demanding environments.
• ±5% Tight Tolerance: Enables accurate filter cutoff frequencies, oscillator timing, and impedance matching without additional trimming or calibration.
• 50 V Rated Voltage: Offers robust headroom for both 3.3 V and 5 V logic systems, reducing derating concerns and improving long-term reliability.

Frequently Asked Questions

1. Q: What makes GJM1555C1H120JB01D different from a standard 0402 MLCC?
   A: This Murata part uses C0G/NP0 dielectric for near-zero temperature coefficient and ±5% tolerance, unlike general-purpose X7R or X5R parts that exhibit wide capacitance drift under voltage and temperature changes.
2. Q: Is GJM1555C1H120JB01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
3. 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 small-batch flexibility for engineering samples.
