✔ RoHS Compliant  /  ✔ SMD  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• High-Voltage Power Supplies: The 1kV rating and C0G/NP0 stability ensure reliable filtering in DC-DC converters and PFC stages.
• Snubber Networks: Low loss characteristics and tight 330pF ±1% make it ideal for damping voltage spikes in switching circuits.
• Medical & Industrial Sensors: Precision capacitance and thermal stability support accurate charge measurement in harsh environments.

Key Features & Advantages

• High Voltage Handling: Rated 1kV enables use in power stages without derating concerns.
• Ultra-Tight Tolerance: ±1% selection maintains circuit accuracy in timing and RC applications.
• Temperature Stable: C0G/NP0 dielectric provides near-zero capacitance drift over -55°C to +125°C.
