Typical Applications & Why This Part Fits

• High-Frequency RF Tuning: The 5.1pF value with ±0.05pF tolerance ensures precise impedance matching in antenna and filter networks, critical for wireless modules.
• Oscillator & Timing Circuits: C0G/NP0 dielectric guarantees capacitance stability over temperature and voltage, ideal for crystal load capacitors and PLL loops.
• Medical & Instrumentation Sensors: Tight tolerance and miniature 0402 size allow dense PCB layouts while maintaining accurate capacitive sensing in portable diagnostic devices.

Key Features & Advantages

• Ultra-Precision Tolerance (±0.05pF): Enables consistent circuit performance without the need for manual tuning, reducing production calibration time.
• High Q & Low ESR: Murata’s GJM series delivers extremely low losses at GHz frequencies, improving signal integrity in RF paths.
• Stable C0G/NP0 Dielectric: Capacitance change is virtually nil across -55°C to +125°C and up to rated voltage, ensuring reliable operation in harsh environments.

Frequently Asked Questions

1. Q: What makes GJM1555C1H5R1WB01D different from a standard 0402 MLCC?
   A: This part offers a strict ±0.05pF tolerance and Murata’s GJM process for ultra-low parasitic effects, making it suitable for high-frequency designs where standard ±0.25pF parts would introduce unacceptable drift.
2. Q: Is GJM1555C1H5R1WB01D 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 flexible small-batch shipments for design verification.
