UCY2E121MHD

The UCY2E121MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for demanding power applications. It provides 120 µF capacitance at a 250 V rating with a polarized radial-lead package and is targeted for power-supply, ballast and automotive electronics where long life and high ripple handling are required.

Key performance highlights include high ripple-current capability across frequency, long endurance at elevated temperature, AEC-Q200 qualification, and RoHS compliance—making it suitable for designs that require robust, long-lived bulk capacitance in a compact form.

Key Features

• Electrical Performance: Rated capacitance 120 µF with tolerance ±20% and rated voltage 250 V; low dissipation factor (tan δ) of 0.20 measured at 20°C, 120 Hz.
• High Ripple-Current Capability: Handles 845 mA ripple at 120 Hz and 1.69 A at 100 kHz, enabling improved smoothing and decoupling across low and high-frequency power rails.
• Long Endurance at Elevated Temperature: Designed for 12,000 hours of load life at +105°C under DC bias plus rated ripple current (series-level endurance per datasheet).
• Mechanical Package: Radial lead can, size φ16 × 25L with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and robust PCB placement.
• Leakage and Reliability: Specified leakage current up to 1,300 µA and performance characteristics traceable to the UCY series datasheet.
• Compliance & Qualification: AEC-Q200 qualified and RoHS compliant for regulated environments and automotive-grade development.
• Packaging Options: Available in bulk (no terminal forming) or bag packing to support production and prototyping workflows.

Typical Applications

• Power Supplies: Bulk smoothing and energy storage for switch-mode power supplies and linear regulators, benefiting from high ripple tolerance and low dissipation.
• Ballasts and Lighting Drivers: Designed for ballast-type applications where sustained ripple and elevated operating temperature endurance are required.
• Automotive Electronics: Suitable for automotive electronic modules requiring AEC-Q200 qualified capacitors for power filtering and decoupling.
• DC–DC Converters and Motor Drives: Decoupling and energy buffering in converters and drive circuits that demand robust ripple current handling over a wide frequency range.

Unique Advantages

• High-frequency and low-frequency ripple capability: Specified ripple current at 120 Hz and 100 kHz lets a single component cover a broad range of power-noise mitigation needs.
• Extended high-temperature life: 12,000-hour endurance at +105°C supports long service intervals and reliable performance under thermal stress.
• AEC-Q200 qualification: Enables use in regulated and reliability-focused automotive designs where component qualification is required.
• Compact radial can format: φ16 × 25L can with 7.5 mm lead spacing provides a space-efficient solution for through-hole PCB layouts.
• RoHS compliant: Meets regulatory requirements for restricted substances in electronic assemblies.
• Practical packaging choices: Bulk and bag packing options simplify procurement for prototypes and volume production alike.
