Key Features

• Capacitance and Voltage — 820 µF rated capacitance with a 63 V rated voltage and ±20% tolerance provides bulk energy storage and smoothing for power rails.
• Low Impedance — Specified impedance of 86 mΩ supports effective filtering at power frequencies and reduces ripple on DC rails.
• High Ripple Current Capacity — Rated ripple current of 1.942 A at 120 Hz and 2.59 A at 10 kHz supports both low- and high-frequency ripple handling in switching environments.
• Loss Angle (tan δ) — tan δ of 0.09 measured at 20 °C, 120 Hz, enabling predictable dissipation characteristics for thermal and reliability planning.
• Leakage Current — Specified leakage current of 1,549.8 µA for predictable standby and bias behavior after voltage application.
• High Endurance — Life rating of 8000 hours at 105 °C under rated conditions for long-term stability in elevated-temperature environments.
• Robust Operating Range & Mechanical — Temperature range −55 °C to 105 °C; radial-lead can package with dimensions φ18 × 25 mm and 7.5 mm lead spacing (±0.5 mm).
• AEC-Q200 Rated — AEC-Q200 rating is specified in the product data, aligning the part with requirements for high-reliability electronic designs.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to suit production and prototyping workflows.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple current capacity make it suitable for output and bulk filtering in switching regulators.
• Automotive Electronics — AEC-Q200 rating and extended temperature endurance support use in automotive control modules and vehicle power systems.
• DC–DC Converters — High ripple handling and stable capacitance over temperature help stabilize DC–DC converter outputs and transient response.
• Industrial Power Systems — Long endurance at 105 °C and robust leakage/tan δ characteristics support continuous operation in industrial electronic equipment.

Unique Advantages

• Designed for High Duty Cycles: 8000 hours endurance at 105 °C provides predictable lifetime performance under sustained thermal stress.
• High-Frequency Performance: Specified ripple current at 10 kHz (2.59 A) and low impedance (86 mΩ) enable effective filtering across a broad frequency range.
• Compact Power Density: Miniature φ18 × 25 mm can packaging delivers substantial capacitance (820 µF) in a small footprint for space-constrained designs.
• Automotive-Grade Reliability: Inclusion of an AEC-Q200 rating supports qualification-conscious designs that require recognized reliability standards.
• Predictable Thermal Behavior: Measured tan δ (0.09 at 20 °C, 120 Hz) and specified leakage current allow accurate thermal and power-loss budgeting.
