Typical Applications & Why This Part Fits

• RF Impedance Matching Networks: With a tight ±0.05 pF tolerance and C0G/NP0 stability, this part ensures consistent impedance control across temperature in 2.4 GHz ISM band designs.
• VCO (Voltage Controlled Oscillator) Tank Circuits: The 2.1 pF value is ideal for fine-tuning resonant frequencies in low-phase-noise oscillators, while the 50 V rating handles transient peaks without derating.
• High-Speed Data Line Coupling: In 0402 footprint, its low parasitic inductance and stable capacitance suit DC-blocking in SerDes channels where exact coupling capacitance matters.

Key Features & Advantages

• Ultra-Tight Tolerance: ±0.05 pF ensures minimal variation in critical timing and matching circuits, reducing production calibration steps.
• C0G/NP0 Dielectric: Capacitance change of ±30 ppm/°C over -55 to +125 °C guarantees stable performance in temperature-varying environments.
• High-Q & Low ESR: Murata’s advanced ceramic process delivers low losses up to several GHz, making it suitable for RF filters and impedance transformers.

Frequently Asked Questions

1. Q: What makes GJM1555C1H2R1WB01D different from a standard 0402 capacitor?
   A: This Murata GJM series part offers an exceptionally tight ±0.05 pF tolerance and C0G/NP0 temperature stability, whereas general-purpose capacitors often have ±0.5 pF or X7R dielectrics that drift with temperature.
2. Q: Is GJM1555C1H2R1WB01D 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. Contact our sales team for flexible quantity requests.
