Key Features

• Capacitance & Voltage — 150 µF rated capacitance with a 160 V working voltage and ±20% tolerance, providing stable energy storage for mid-voltage power circuits.
• High Ripple Current — 760 mA at 120 Hz (low frequency) and 1.52 A at 100 kHz (high frequency), enabling effective smoothing and decoupling in power supplies across a wide frequency range.
• Long Endurance — Rated life of 12,000 hours at 105°C, supporting long-term reliability under elevated temperature and continuous-load conditions.
• Temperature Range — Operating from −40°C to +105°C, suitable for applications with wide ambient variations.
• Loss Characteristics — tanδ (DF) up to 0.20 measured at 20°C, 120 Hz, for predictable dissipation characteristics in AC and ripple environments.
• Leakage Performance — Specified leakage current of 1,060 µA, consistent with robust DC performance and predictable standby losses.
• Compact Radial Package — φ12.5 × 25 mm can with 5.0 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assembly and hand-assembly or automated insertion options; available in bulk or bag packing.
• AEC-Q200 Qualified — Specified AEC-Q200 rating and explicit application listing for automotive use, supporting deployment in vehicle electronic modules.

Typical Applications

• Automotive Power Electronics — Energy buffering and ripple suppression in automotive ECUs and power modules that require AEC-Q200‑grade components.
• Power Supplies — Smoothing and decoupling in intermediate DC rails and power-supply outputs where elevated ripple currents occur.
• Ballast and Lamp Drivers — Filtering and energy storage for ballast circuits and lamp driver power stages as noted for the UCY series.

Unique Advantages

• Proven Endurance: 12,000‑hour life at 105°C reduces maintenance and replacement cycles in continuous-duty environments.
• High Frequency Capability: Rated high-frequency ripple current (1.52 A at 100 kHz) improves performance in switching and high-speed power stages.
• Automotive-Grade Qualification: AEC-Q200 designation aligns the part with automotive reliability expectations for vehicle electronics.
• Compact Footprint: φ12.5 × 25 mm can and 5 mm lead spacing deliver a space-efficient solution for through-hole designs.
• Wide Operating Range: −40°C to +105°C operation ensures stable function across harsh ambient conditions.
