Key Features

• Capacitance & Voltage: 330 µF rated at 25 V, with ±20% tolerance for bulk energy storage and decoupling.
• Low ESR: 20 mΩ equivalent series resistance measured at 100 kHz, improving power delivery efficiency and reducing losses.
• High Ripple Current: Rated ripple current of 4.6 A at 100 kHz and 2.3 A at 120 Hz, enabling effective smoothing under high-frequency switching conditions.
• Wide Temperature Range: Guaranteed operation from -55°C to 125°C to cover harsh thermal environments.
• Long Life at Elevated Temperature: 4000 hours life rating at 125°C under specified endurance test conditions.
• AEC-Q200 Qualification: Meets AEC-Q200 requirements for high-reliability automotive use.
• SMD Chip Package: Surface-mount, radial can-style SMD with body dimensions approximately 1.0 cm × 1.0 cm and recommended land pattern 1.03 cm × 1.03 cm.
• Reflow Compatible: Compatible with lead-free reflow soldering; peak temperature up to 260°C supported per product specifications.
• Leakage Current Specification: Leakage current not more than 0.03CV after 2 minutes' application of rated voltage, per datasheet conditioning.
• RoHS Compliant: Conforms to RoHS directive requirements.

Typical Applications

• Automotive power electronics: Use where AEC-Q200 qualification and high ripple handling are required for power rail smoothing and decoupling in vehicle systems.
• Engine and ECU modules: Support for control units that demand stable capacitance across -55°C to 125°C and long endurance at elevated temperature.
• Infotainment and body electronics: SMD form factor and low ESR enable compact board layouts and efficient filtering in in-vehicle electronic subsystems.

Unique Advantages

• Automotive-grade reliability: AEC-Q200 compliance and a 4000-hour life at 125°C provide confidence for long-term in-vehicle deployments.
• High ripple tolerance: Rated ripple currents up to 4.6 A at 100 kHz reduce heat build-up and improve performance on switching power supplies.
• Efficient power delivery: Low ESR (20 mΩ at 100 kHz) minimizes losses and supports tighter voltage regulation in power-sensitive circuits.
• Compact SMD footprint: 1.0 cm × 1.0 cm package and defined land pattern simplify PCB layout and enable dense board integration.
• Robust soldering profile: Compatibility with lead-free reflow up to 260°C supports modern assembly processes without special handling.
• Stable performance across temperature: Tight impedance and ESR characteristics across -55°C to 125°C help maintain filtering and decoupling effectiveness in extreme conditions.
