Typical Applications & Why This Part Fits

• RF Tuning & Impedance Matching: The ultra-low 1.8pF capacitance and C0G class-1 dielectric ensure minimal drift with temperature and voltage, making it ideal for precise RF matching networks in wireless modules.
• High-Voltage DC-DC Converters: Rated at 100V in a compact 0402 package, this capacitor suits snubber circuits or feedback loops where stable, low-loss performance under high voltage is critical.
• Sensor Interface Circuits: The ±0.25pF tight tolerance allows accurate coupling or filtering in capacitive sensor conditioning, especially where environmental changes must not shift the nominal value.

Key Features & Advantages

• Class-1 C0G/NP0 Dielectric: Provides nearly zero capacitance change over temperature (-55°C to +125°C) and voltage, ensuring predictable circuit behavior in precision applications.
• High Voltage Rating in Small Footprint: 100V rating in a 0402 size saves board space while supporting power management designs that require higher voltage margins.
• Stringent Tolerance Control: ±0.25pF tolerance minimizes part-to-part variation, enabling consistent RF performance without additional tweaking or calibration steps.

Frequently Asked Questions

1. Q: What makes GRM1555C2A1R8CA01D different from a standard 1.8pF MLCC?
   A: Unlike generic X7R or X5R parts, this Murata MLCC uses a C0G dielectric and a ±0.25pF tolerance, offering far better temperature stability (ΔC≈±30ppm/°C) and tighter initial accuracy, which is essential for RF and timekeeping circuits.
2. Q: Is GRM1555C2A1R8CA01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, meeting current environmental regulations for electronic assemblies.
3. Q: What is the MOQ? Can we get small batches?
   A: We support small batch orders and fast BOM kitting support at SZYY, including small-quantity prototyping for design validation, ensuring flexibility even for low-volume runs.
