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

Typical Applications & Why This Part Fits

• RF Tuning & Impedance Matching: The ±1% tight tolerance and C0G/NP0 temperature characteristics ensure minimal capacitance drift across -55°C to +125°C, critical for maintaining resonance in 50Ω RF paths.
• High-Speed Signal Coupling: With 39pF value and stable dielectric, this cap provides predictable AC coupling for gigabit-rate data lines without introducing signal distortion or phase jitter.
• Precision Timing Circuits: The 50V DC rating combined with 0402 footprint suits compact oscillator designs where exact capacitance (39pF) defines oscillation frequency within ±1% accuracy.

Key Features & Advantages

• Ultra-Tight Tolerance (±1%): Enables design with tight electrical specifications, reducing the need for in-circuit trimming or calibration.
• Class 1 C0G/NP0 Dielectric: Offers virtually zero voltage and temperature coefficient, delivering predictable performance across environmental extremes.
• Miniature 0402 Package: Saves PCB space while maintaining high self-resonant frequency (SRF), ideal for dense RF and portable device layouts.

Frequently Asked Questions

1. Q: What makes GJM1555C1H390FB01D different from a standard MLCC?
   A: Unlike X7R or X5R dielectrics, this Murata part uses C0G/NP0 material, ensuring capacitance stability over voltage, temperature, and aging—essential for precision analog and RF applications.
2. Q: Is GJM1555C1H390FB01D 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 engineers.
