UCY2D151MHD

The UCY2D151MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can designed for demanding power applications. It provides 150 µF capacitance at 200 V with a compact φ12.5 × 35.5 mm package and 5 mm lead spacing.

Engineered for high ripple environments and extended operational life, this AEC‑Q200 qualified device targets automotive and industrial power-supply applications that require robust ripple handling, broad temperature range, and long-term endurance.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance at 200 V, with tolerance ±20% (–20% to +20%) measured at 120 Hz, 20°C.
• High Ripple Current — Low-frequency ripple current rated 965 mA at 120 Hz and high-frequency ripple current 1.93 A at 100 kHz, improving performance in switching and high-frequency power stages.
• Low Loss (tan δ) — Dissipation factor (tan δ) 0.20 measured at 120 Hz, 20°C, for controlled ESR and thermal behavior.
• Long Life Endurance — Rated for 12,000 hours at 105°C under D.C. bias plus rated ripple current; endurance limits specify capacitance within ±20% and leakage not exceeding initial values after test.
• Leakage Current — Specified leakage current 1,300 µA (after 1 minute at rated voltage, 20°C), consistent with the series leakage formula (0.04CV + 100 µA).
• Temperature Range — Operates from –40°C to +105°C, suitable for wide ambient conditions.
• Package & Mounting — Radial lead can, φ12.5 mm diameter × 35.5 mm length, lead spacing 5.0 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Standards & Compliance — AEC‑Q200 qualified and RoHS compliant for regulated applications.

Typical Applications

• Power Supplies — Bulk filtering and smoothing in DC power supplies and intermediate bus capacitors where high ripple current and long life are required.
• Automotive Electronics — Power conditioning and decoupling in automotive control modules and power subsystems, supported by AEC‑Q200 qualification.
• Ballasts and Industrial Power — Energy storage and ripple handling in ballast circuits and industrial power equipment as indicated by the UCY series guidance.

Unique Advantages

• High ripple capability: 1.93 A at 100 kHz and frequency-dependent coefficients allow predictable performance across switching frequencies.
• Extended operational life: 12,000-hour endurance at 105°C supports long-term reliability in continuous-load environments.
• AEC‑Q200 qualified: Qualification suitable for automotive-grade design requirements and rigorous reliability expectations.
• Compact radial form factor: φ12.5 × 35.5 mm can with 5 mm lead spacing provides a space-efficient solution for through-hole assemblies.
• Measured leakage specification: Leakage current limited to 1,300 µA (per part data), allowing predictable bias and standby current planning.
• Regulatory compliance: RoHS-compliant construction aligns with environmental regulations.
