Key Features

• Capacitance and Voltage: 180 µF nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20%.
• Low Impedance: Characteristic impedance of 294 mΩ to support reduced voltage ripple and better transient performance.
• High Ripple Current Capability: Low‑frequency ripple current 578.5 mA at 120 Hz and high‑frequency ripple current 890 mA at 10 kHz for effective smoothing in switching supplies.
• Long Endurance: Rated life of 5000 hours at 105°C to support extended operation in high‑temperature environments.
• Wide Temperature Range: Operating temperature from −55°C to 105°C for use across broad environmental conditions.
• Leakage and Losses: Leakage current specified at 340.2 µA and tangent of loss angle (tan δ) 0.09 measured at 20°C, 120 Hz.
• Package and Mounting: Radial lead can (φ10 × 20 mm) with 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing; mass production status.
• Automotive‑Grade Reliability: AEC‑Q200 rated for use in applications where component qualification to automotive passive requirements is required.

Typical Applications

• Switching Power Supplies: Bulk and output filtering where compact, low‑impedance capacitance reduces ripple and stabilizes converters.
• Power Conditioning: Decoupling and smoothing in power rails that require sustained ripple handling and leakage control.
