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

Typical Applications & Why This Part Fits

• Power Supply Filtering: The 1KV rating and C0G/NP0 dielectric ensure minimal capacitance change under high DC bias, making it ideal for snubber circuits in switching power supplies.
• Telecom Infrastructure: With 330PF capacitance and ±5% tolerance, it provides precise coupling and decoupling in RF modules where frequency stability is critical.
• Industrial DC-DC Converters: The 1206 package offers robust mechanical strength and low ESR, suitable for high-voltage bus capacitors in industrial converters operating up to 1KV.

Key Features & Advantages

• High Voltage Capability: Rated for 1KV, it handles stringent insulation requirements in automotive and industrial power stages.
• Temperature-Stable Dielectric: C0G/NP0 ensures nearly zero capacitance drift from -55°C to +125°C, critical for timing circuits.
• Low Loss & High Q: Excellent for resonant tank circuits and high-frequency applications where minimal dissipation is required.
