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

Typical Applications & Why This Part Fits

• RF Tuning & Matching Networks: The 0.9pF ultra-low capacitance and NP0 (C0G) temperature stability ensure precise impedance matching in RF front-end modules, minimizing signal loss.
• High-Voltage Coupling: With a 200V rating in a tiny 0402 footprint, it decouples high-voltage bias lines in test equipment or power amplifiers where board space is limited.
• Resonant Circuit Compensation: The tight ±0.1pF tolerance allows accurate frequency setting in oscillators and filters, maintaining consistent performance across temperature changes.

Key Features & Advantages

• Ultra-Low Capacitance (0.9pF): Enables extremely high-frequency coupling without loading the signal, ideal for GHz-range circuits.
• NP0 Dielectric: Provides near-zero capacitance drift with temperature and voltage, ensuring stable circuit behavior.
• High Voltage (200V) in 0402: Handles elevated bias voltages where standard low-voltage MLCCs would fail, all within a minimal board footprint.

Frequently Asked Questions

1. Q: What makes GQM1555C2DR90BB01D different from a standard MLCC?
   A: Unlike general-purpose MLCCs, this part offers an extremely low capacitance value (0.9pF) combined with a high voltage rating (200V) and NP0 stability, making it suitable for RF and precision applications where standard capacitors cannot meet tolerance or voltage demands.
2. Q: Is GQM1555C2DR90BB01D 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. Flexible quantities are available for engineering samples.
