✔ RoHS Compliant  /  ✔ 0805 Package  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• DC‑DC Converter Snubbers: The 250V rating and ±1% tolerance ensure reliable ringing suppression in high‑voltage power stages.
• High‑Frequency Timing Circuits: C0G/NP0 dielectric offers negligible capacitance change with temperature, maintaining oscillator accuracy.
• Sensor Interface Filtering: 220pF value combined with low ESR and tight tolerance reduces noise in 250V industrial sensors.

Key Features & Advantages

• High Voltage Rating (250V): Enables safe operation in power‑supply and automotive‑grade designs without derating concerns.
• ±1% Tolerance: Provides predictable performance for calibration‑critical and IMUs requiring exact capacitance.
• C0G/NP0 Dielectric: Ultra‑stable over temperature (–55°C to +125°C) and voltage, ideal for time‑constant circuits.
