Feature Highlights
● High Capacitance Density: Delivers substantial 10µF capacitance in the compact 0805 form factor measuring just 2.0mm × 1.25mm, achieving exceptional volumetric efficiency through advanced dielectric materials and thin-layer multilayer construction technology.
● X5R Temperature Stability: Maintains capacitance within ±15% across the -55°C to +85°C temperature range, providing predictable performance across typical consumer and industrial operating environments while balancing cost-effectiveness with thermal reliability.
● Robust Internal Construction: Employs nickel inner electrodes with proven multilayer stacking technology, delivering reliable performance under thermal cycling, mechanical stress, and voltage bias conditions typical of demanding electronic applications.
● Precision Tolerance: The ±10% (K tolerance) specification ensures tighter capacitance control compared to ±20% alternatives, critical for timing circuits, filters, and decoupling applications requiring predictable component values.
FAQ
Q: What DC bias derating considerations apply to this capacitor?
A: X5R dielectric capacitors experience significant capacitance reduction under applied DC bias voltage, and this effect intensifies with higher capacitance values in compact packages, so designers must consult Samsung's DC bias curves to verify effective capacitance at actual operating voltage, often derating to 30-50% of nominal value at rated voltage.
Q: How does the X5R dielectric compare to X7R for this application?
A: X5R offers equivalent capacitance stability (±15%) but limits maximum temperature to +85°C versus +125°C for X7R, making this component suitable for commercial applications while X7R alternatives are required for automotive or high-temperature industrial environments.
