✔ RoHS Compliant  /  ✔ 0603  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Automotive under-hood electronics: The X8R dielectric rating ensures stable capacitance up to 150°C, matching the 50V rating for powertrain and engine control modules.
• DC-DC converter output filtering: 10000PF provides effective high-frequency noise suppression at 50V, while the 0603 footprint suits compact power designs.
• Industrial sensor interfaces: ±10% tolerance accommodates decoupling and coupling tasks where precise capacitance is less critical than voltage and temperature resilience.

Key Features & Advantages

• X8R dielectric stability: Maintains capacitance over -55°C to +150°C, enabling reliable operation in harsh thermal environments.
• 50V voltage rating: Offers a strong safety margin for 24V and 48V bus rails, reducing derating complexity.
• 0603 industry-standard package: Supports automated assembly and dense PCB layouts, simplifying supply chain logistics.
