✔ RoHS Compliant  /  ✔ 0603 Package  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• RF Impedance Matching Networks: The ±0.05pF tight tolerance and C0G/NP0 stability ensure precise impedance tuning for antennas and filters in cellular, GPS, and Bluetooth modules, minimizing signal reflection.
• VCO & PLL Loop Filters: At 0.2pF, this capacitor enables fine frequency adjustments in voltage-controlled oscillators and phase-locked loops, where sub-picofarad values are critical for low phase noise and lock accuracy.
• High-Voltage Sensor Interfaces: With a 250V rating, it handles transient spikes in industrial sensor front-ends and test equipment, while C0G/NP0 dielectric ensures negligible capacitance shift under DC bias.

Key Features & Advantages

• Ultra-Tight ±0.05pF Tolerance: Provides unmatched repeatability in high-frequency designs, eliminating the need for manual tuning in production environments.
• C0G/NP0 Dielectric Class 1 Performance: Offers near-zero capacitance change with temperature (-55°C to +125°C) and voltage, making it ideal for resonant circuits and timing applications.
• 250V DC Rating in 0603 Size: Delivers high voltage handling in a compact footprint, saving board space in power-constrained RF and instrumentation designs.

Frequently Asked Questions

1. Q: What makes GQM1875C2ER20WB12D different from a standard 0603 MLCC?
   A: Its ±0.05pF tolerance and 250V rating are specialized for RF and high-voltage precision circuits—standard MLCCs typically offer looser tolerances (e.g., ±0.25pF or ±5%) and lower voltage ratings in the same package.
2. Q: Is GQM1875C2ER20WB12D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, meeting EU directive requirements for environmental safety.
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 for this ultra-low capacitance value.
