Typical Applications & Why This Part Fits

• RF impedance matching networks: The ultra‑low capacitance tolerance (±0.05 pF) ensures consistent resonant frequency in 2.4 GHz and 5 GHz wireless modules.
• High‑speed digital decoupling: At 3.3 pF and 50 V rating, it effectively filters high‑frequency noise in SerDes or DDR memory power rails without impacting signal integrity.
• Sensor interface circuits: C0G’s nearly zero temperature coefficient (NP0) guarantees stable capacitance from –55 °C to +125 °C, essential for precision analog measurements.

Key Features & Advantages

• Tight ±0.05 pF tolerance: Enables repeatable performance across production batches, reducing the need for manual tuning.
• Murata’s GJM series construction: Low equivalent series resistance (ESR) and high self‑resonant frequency optimize performance in GHz‑range applications.
• Full 50 V DC rating: Offers reliable headroom even in 3.3 V or 5 V circuits, ensuring long‑term stability under voltage spikes.

Frequently Asked Questions
