The UCY2D151MHD3 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCY series. It is a radial lead, polarized can designed for high ripple current and extended life in demanding power applications.

Optimized for power-supply and ballast use and specified for automotive applications, this part combines a 150 µF capacitance at 200 V with high ripple performance and long endurance for sustained operation up to 105°C.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a rated voltage of 200 V and capacitance tolerance of ±20%.
• High Ripple Current — Low-frequency ripple current rated at 945 mA (120 Hz) and high-frequency ripple current rated at 1.89 A (100 kHz), supporting demanding power-conditioning tasks.
• Long Life / Endurance — Load-life specification of 12,000 hours at +105°C under rated DC bias plus rated ripple current, enabling extended field service life.
• Electrical Loss & Leakage — Tangent of loss angle (tan δ) specified at 0.20 (20°C, 120 Hz) and leakage current listed at 1,300 µA, allowing predictable performance in filter and smoothing circuits.
• Temperature Range — Rated for operation from −40°C to +105°C to cover wide environmental conditions.
• Compact Radial Package — Metal can radial lead package with dimensions φ16 × 25L and 7.5 mm lead spacing, available in bulk (no terminal forming) or bag packing.
• Standards & Compliance — AEC‑Q200 qualified and RoHS compliant, aligning with automotive and environmental requirements.

Typical Applications

• Power supplies — Bulk decoupling and smoothing where high ripple current capability and long life at elevated temperatures are required.
• Ballast circuits — Suited to ballast and lamp-driver applications that demand stable capacitance and reliable endurance under continuous AC ripple.
• Automotive power electronics — Applicable in automotive systems that require components with AEC‑Q200 qualification and operation to +105°C.

Unique Advantages

• High ripple handling: Specified ripple currents at both low and high frequencies enable effective filtering across a wide frequency range.
• Extended high-temperature life: 12,000-hour endurance at 105°C provides confidence for long-duration, high-heat deployments.
• Compact radial form factor: φ16 × 25L can and 7.5 mm lead spacing deliver a small footprint for space-constrained power designs.
• Predictable electrical behavior: Specified tan δ and leakage current values support reliable circuit modeling and margining in design.
• Automotive-grade qualification: AEC‑Q200 qualification and RoHS compliance reduce qualification overhead for automotive-related projects.
• Packaging versatility: Available in bulk or bag packing to suit prototyping and production needs.
