Designed for power supply and ballast use and specified for automotive applications, the UCY2E181MHD pairs high-frequency ripple capability with long endurance to support robust power conditioning in demanding environments.

Key Features

• Capacitance and Tolerance 180 µF nominal capacitance with ±20% tolerance measured at 120 Hz, 20°C.
• Rated Voltage 250 V DC rating suitable for medium-voltage power applications.
• High Ripple Current Capability Low-frequency ripple current of 1.11 A at 120 Hz and high-frequency ripple current of 2.22 A at 100 kHz, enabling improved filtering performance across a wide frequency range.
• Loss Characteristics Tangent of loss angle (tanδ) of 0.20 measured at 20°C, 120 Hz, supporting predictable ESR behavior in AC conditions.
• Leakage Current Rated leakage current of 1900 µA, specified after application of rated voltage.
• Operating Temperature and Endurance Wide operating range from −40°C to +105°C and rated for 12,000 hours at 105°C under DC bias plus rated ripple current.
• Mechanical Package Radial lead, can-style package with dimensions φ16 × 30.5 mm, lead spacing 7.5 mm (±0.5 mm) for through-hole mounting.
• Reliability and Compliance AEC-Q200 qualified for automotive-grade reliability and RoHS compliant.
• Packing Options Available in bulk (no terminal forming) and bag packing to suit production handling preferences.

Typical Applications

• Automotive electrical systems — Energy storage and smoothing in power subsystems where AEC-Q200 qualification and extended high-temperature life are required.
• Power supplies — Bulk filtering and ripple suppression in medium-voltage DC power supplies benefiting from high ripple current capability.
• Ballasts and lighting drives — AC ripple handling and endurance under continuous load for ballast circuits.

Unique Advantages

• High ripple endurance: Specified ripple currents of 1.11 A (120 Hz) and 2.22 A (100 kHz) reduce thermal stress and improve filtering in both low- and high-frequency applications.
• Long life at elevated temperature: Rated for 12,000 hours at 105°C, enabling sustained operation in hot environments and minimizing replacement frequency.
• Automotive-grade qualification: AEC-Q200 rating supports use in designs that demand automotive reliability and quality control.
• Compact radial package: φ16 × 30.5 mm can with 7.5 mm lead spacing simplifies through-hole mounting while conserving PCB area.
• Predictable electrical behavior: tanδ = 0.20 (20°C, 120 Hz) and specified leakage current provide consistent performance for circuit design and margining.
• RoHS compliant and packaging flexibility: Environmentally compliant materials and bulk or bag packing options for streamlined assembly handling.
