Key Features

• Capacitance & Voltage — 47 µF nominal capacitance rated at 63 V, with ±20% tolerance at 120 Hz, 20 °C.
• Conductive Polymer Construction — Solid polymer electrolyte provides low ESR and improved high-frequency performance compared to conventional electrolytics.
• Low ESR & High Ripple Handling — ESR 35 mΩ measured at 100 kHz; ripple current ratings of 750 mA at 120 Hz and 1.5 A at 100 kHz enable effective smoothing and decoupling under dynamic loads.
• High-Temperature Endurance — Designed for long life at elevated temperature: 4000 hours at 135 °C with endurance criteria that limit capacitance change to ±20% and ESR increase to 200% of initial values.
• Surface-Mount Package — Chip-type SMD (radial can SMD) for automated assembly and compact board-level integration; recommended land pattern dimensions 10.3 mm × 10.3 mm.
• Reflow Compatible — SMD type compatible with lead-free reflow soldering (260 °C peak) per series specification.
• Wide Temperature Range — Rated for continuous operation from -55 °C to +135 °C.
• Regulatory & Quality — RoHS compliant and AEC-Q200 qualified for applications requiring recognized reliability standards.
• Leakage Current Specification — After 2 minutes of rated-voltage application, leakage current is specified as not more than 0.03 CV (per datasheet procedure).

Typical Applications

• Automotive Electronics — Suitable for electronic control units and modules where AEC-Q200 qualification and high-temperature endurance are required.
• Power Supply Filtering — Low ESR and high ripple-current capability make it suitable for bulk filtering and decoupling in power rails and DC–DC converter outputs.
• High-Reliability Industrial Systems — Use in electronics operating in elevated-temperature environments that require stable capacitance and controlled leakage over long service life.

Unique Advantages

• Long High-Temperature Life: 4000 hours at 135 °C provides predictable end-of-life characteristics for mission-critical designs.
• High Ripple Performance: Low ESR (35 mΩ @100 kHz) plus up to 1.5 A ripple capability at high frequency reduce thermal stress and improve converter stability.
• AEC-Q200 Qualification: Recognized qualification supports selection for automotive-grade and similarly demanding applications.
• Reflow-Ready SMD Form Factor: Chip-type SMD construction and lead-free 260 °C reflow compatibility simplify assembly and support automated manufacturing.
• Stable Endurance Characteristics: Datasheet-specified limits on capacitance change, tan δ, ESR, and leakage after endurance and damp-heat testing provide verifiable reliability metrics.
