Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance for bulk energy storage and decoupling in power circuits.
• Low Loss / Dissipation Factor — tanδ = 0.10 measured at 20°C, 120 Hz, supporting efficient performance in AC and ripple environments.
• High Ripple Current Handling — Low-frequency ripple current 670 mA (120 Hz) and high-frequency ripple current 1.34 A (10 kHz) to support significant AC stress on power rails.
• Leakage Current — Specified leakage current of 235 µA after standard voltage application, enabling predictable standby and bias behavior.
• Wide Temperature & Long Endurance — Operating range −55°C to +105°C with a rated endurance of 5000 hours at 105°C for long-term stability in elevated-temperature environments.
• Automotive-Grade Qualification — AEC-Q200 rating noted in specifications for designs requiring component-level automotive qualification.
• Surface-Mount, Tape-Packaged — Radial can SMD package (φ12.5 × 13.5 mm) supplied in embossed carrier taping for automated pick-and-place assembly; vibration resistant.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.

Typical Applications

• Automotive power modules — Bulk energy storage and smoothing where a 50 V rating, 470 µF capacitance and AEC-Q200 qualification are required.
• Embedded power supplies — Output filtering and decoupling in DC–DC converters benefiting from the part’s high-frequency ripple capability (1.34 A at 10 kHz).
• Industrial control electronics — High-temperature operation up to 105°C and 5000-hour endurance for sustained performance in demanding environments.

Unique Advantages

• High-capacitance SMD form factor: 470 µF in a φ12.5 × 13.5 mm chip-type can provides significant bulk capacitance while supporting surface-mount assembly.
• Robust ripple performance: Dual-specified ripple currents (670 mA at 120 Hz and 1.34 A at 10 kHz) enable reliable handling of both low- and high-frequency ripple components.
• Long high-temperature life: 5000 hours at 105°C delivers proven endurance for extended operation in hot environments.
• Automotive-ready qualification: AEC-Q200 rating supports use in applications that require automotive-level component qualification.
• Predictable leakage and loss characteristics: Specified leakage current (235 µA) and low tanδ (0.10) support predictable circuit behavior and efficient performance.
• Manufacturing-friendly packaging: Embossed carrier taping and vibration resistance simplify automated placement and improve assembly yield.
