UCY2E151MHD

The UCY2E151MHD is a miniature, high‑reliability aluminum electrolytic capacitor in a radial lead can designed for demanding power applications. As part of Nichicon’s UCY series, it combines a compact φ18×25 mm package and radial lead termination with performance optimized for high ripple current and long endurance at elevated temperatures.

Engineered for power supplies, ballast circuits and automotive use, the device delivers a 150 µF capacitance at 250 V rating with guaranteed performance across −40°C to +105°C and a rated lifetime of 12,000 hours at 105°C.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance at a 250 V working voltage, ±20% tolerance.
• High ripple current capability — Low‑frequency ripple current 970 mA (120 Hz) and high‑frequency ripple current 1.94 A (100 kHz) to support power rails with significant AC loading.
• Long endurance — Load life rated for 12,000 hours at 105°C under DC bias plus rated ripple current.
• Electrical loss (tan δ) — tan δ max. 0.20 measured at 20°C, 120 Hz (for 250 V rating), supporting stable loss characteristics in power applications.
• Leakage current — Specified leakage current of 1,600 µA.
• Package & leads — Radial can, φ18 mm diameter × 25 mm length with 7.5 mm lead spacing (±0.5 mm) and lead diameter 0.8 mm.
• Environmental & qualification — RoHS compliant and AEC‑Q200 qualified.

Typical Applications

• Power supplies — Bulk and filter capacitance for DC rails, benefiting from high ripple current capability and long life at 105°C.
• Ballast circuits — Suited for ballast application where sustained ripple current and thermal endurance are required.
• Automotive electronics — AEC‑Q200 qualification and wide operating temperature range (−40°C to +105°C) make it suitable for automotive power modules and related applications.
• High‑ripple power rails — Designed to withstand repeated AC loading and high frequency ripple up to 100 kHz with specified ripple current ratings.

Unique Advantages

• Designed for sustained ripple — Clear ripple current ratings at both low (970 mA @120 Hz) and high frequency (1.94 A @100 kHz) reduce margining when designing power filters.
• High thermal endurance — 12,000‑hour rated life at 105°C supports durability in elevated‑temperature environments.
• Automotive‑grade qualification — AEC‑Q200 qualification provides an extra level of reliability assessment for vehicle and transportation electronics.
• Compact radial can — φ18×25 mm footprint with 7.5 mm lead spacing fits compact board layouts while preserving capacitance and ripple performance.
• Stable dielectric loss — Low tan δ (0.20 at 120 Hz, 20°C) helps maintain efficiency and predictable heating under AC stress.
• Regulatory compliance — RoHS compliance supports environmental requirements for modern electronics production.
