✔ RoHS Compliant / ✔ 0402 Package / ✔ Murata Quality / ✔ Long‑Term Supply
Typical Applications & Why This Part Fits
- RF Impedance Matching Networks: The 1.9pF value and tight ±0.05pF tolerance enable precise tuning of antenna matching circuits in IoT modules and wireless transceivers, minimizing return loss.
- High‑Frequency VCO & PLL Loops: C0G/NP0’s extremely low capacitance drift over temperature (–55°C to +125°C) and voltage ensures stable oscillator frequency, critical for 5G and satellite communication systems.
- Sensor Interface Filters: 50V rating provides robust headroom in battery‑powered or automotive sensor front-ends, while the 0402 footprint saves space on dense mixed‑signal PCBs.
Key Features & Advantages
- ±0.05pF Tight Tolerance: Guarantees highly repeatable circuit performance without the need for post‑production tuning, reducing manufacturing cost.
- C0G/NP0 Dielectric: Offers ultra‑low ESR and predictable, flat capacitance across temperature and DC bias – ideal for timing and filter applications.
- 0402 Small Form Factor: Enables high‑density placement in portable and space‑constrained designs while maintaining 50V voltage capability.
