Typical Applications & Why This Part Fits

• RF Matching Networks: The 3.4pF nominal value and ±0.25pF tolerance ensure precise impedance matching in LNA or filter stages for 2.4 GHz and 5 GHz bands.
• Oscillator & PLL Loop Filters: Its C0G/NP0 dielectric provides near-zero capacitance drift with temperature and voltage, critical for stable VCO frequency control.
• High-Speed Data Line Decoupling: At 3.4pF and 50V, this MLCC offers low parasitic inductance in 0402 package, effectively filtering noise on PCIe or DDR signal lines.

Key Features & Advantages

• Ultra-Tight Tolerance: The ±0.25pF rating guarantees repeatable performance across batches, reducing calibration needs in sensitive RF designs.
• Temperature-Stable Dielectric: C0G/NP0 ensures capacitance change less than ±30 ppm/°C, eliminating derating in harsh thermal environments.
• Compact 0402 Footprint: Saves board space while supporting a 50V rating, ideal for miniaturized IoT modules and wearable devices.

Frequently Asked Questions

1. Q: What makes GJM1555C1H3R4CB01D different from a standard 0402 3.3pF MLCC?
   A: This Murata GJM series part holds a ±0.25pF tolerance (vs. typical ±0.5pF) and uses C0G/NP0 dielectric, delivering lower ESR and higher Q factor for critical RF paths.
2. Q: Is GJM1555C1H3R4CB01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, making it suitable for global regulatory approvals.
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. A reel of 10,000 may be split for evaluation without MOQ penalties.
