• Rated Voltage — 16 V DC rating suitable for low-voltage power rails.
• Low Impedance — Typical impedance of 44 mΩ for reduced voltage drop and improved ripple performance.
• Ripple Current Capability — Low-frequency ripple current 2.172 A (120 Hz) and high-frequency ripple current 2.555 A (10 kHz), enabling robust AC ripple handling in power circuits.
• Loss Characteristics — Dissipation factor (tan δ) 0.2 measured at 20°C, 120 Hz (specified for this part).
• Endurance — Rated life of 8,000 hours at 105°C under specified conditions.
• Temperature Range — Operating from -55°C to +105°C for broad environmental tolerance.
• Form Factor & Mounting — Radial lead, can-style package (φ16 × 25 mm), lead spacing 7.5 mm, designed for through-hole mounting.
• Leakage Current — Specified leakage current of 1,584 µA after rated voltage application.
• AEC‑Q200 Qualified — Rated for applications requiring AEC‑Q200 qualification.
• Packaging Options — Available in bulk (no terminal forming) and bag packing for flexible assembly workflows.

Typical Applications

• Switching Power Supplies — Filtering and smoothing on output rails in switching regulator designs, leveraging low impedance and high ripple capability.
• Automotive Electronics — Power filtering and energy buffering in automotive modules where AEC‑Q200 qualification is required.
• Power Rail Decoupling — Bulk capacitance and ripple handling for low-voltage DC power rails in embedded and control systems.

Unique Advantages

• High ripple endurance: Specified ripple currents at both low and high frequencies (2.172 A at 120 Hz, 2.555 A at 10 kHz) reduce stress on upstream regulation and improve hold-up performance.
• Long life at elevated temperature: 8,000 hours at 105°C supports longevity in thermally demanding applications.
• Compact radial can: φ16 × 25 mm package offers significant capacitance in a small footprint for space-constrained designs.
• Low series impedance: 44 mΩ impedance contributes to lower ripple voltage and improved efficiency in power conversion circuits.
• AEC‑Q200 qualification: Enables use in programs that require an established automotive component reliability standard.
• Wide operating range: -55°C to +105°C operation accommodates harsh environmental and temperature cycling conditions.
