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

Typical Applications & Why This Part Fits

• Automotive ECU Power Rails: With 50V rating and X7R stability, this 1.5 µF MLCC delivers reliable decoupling against voltage transients in 12V/48V vehicle boards.
• Industrial Sensor Modules: The 1206 footprint and ±10% tolerance allow compact filtering and energy storage in space-constrained sensor interfaces operating up to 125°C.
• Power Management ICs (PMICs): Its 1.5 µF value matches typical bulk capacitance requirements for input/output smoothing in DC-DC converters, maintaining low ESR across frequency.

Key Features & Advantages

• Wide Temperature Range: X7R dielectric ensures capacitance variation within ±15% from -55°C to +125°C, critical for under-hood automotive use.
• Compact 1206 Size: Balances high capacitance density with solder joint robustness, enabling denser PCB layouts without compromising mechanical strength.
• Murata Quality Assurance: Backed by rigorous AEC-Q200 qualification and lot traceability, reducing field failure risks in safety-critical applications.
