UCA2E151MHD

The UCA2E151MHD is a miniature aluminum electrolytic capacitor in a radial lead can designed for general-purpose power applications. It delivers 150 µF at 250 V with high rated ripple current and a long operational life, targeting power supply and ballast use cases where compact size and sustained ripple performance matter.

Key Features

• Rated Capacitance & Voltage — 150 µF capacitance at a rated voltage of 250 V.
• High Ripple Current — Rated ripple current of 1.5 A at 100 kHz and 1.5 A (1500 mA) listed; 750 mA at 120 Hz is specified for low-frequency ripple.
• Long Life / Endurance — 12,000 hours load life at 105°C under DC bias plus rated ripple current; endurance criteria include capacitance within ±20% and leakage current meeting initial limits after test.
• Electrical Stability — Capacitance tolerance ±20%; tan δ maximum of 0.15 at the 250 V rating (measured at 120 Hz, 20°C); leakage current specified as not more than 0.04CV + 100 µA after 1 minute at 20°C.
• Temperature Range — Operating temperature range from −25°C to +105°C.
• Compact Radial Package — Radial lead can with case size φ18 × 30.5 mm (L × D: 3.05 × 1.8 cm), lead spacing 7.5 mm and polarized construction for through-hole mounting.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Filtering and energy storage where a compact, high-voltage electrolytic with sustained ripple capability is required.
• Ballasts — Supports AC/DC conversion and smoothing in lighting ballast circuits, using its rated voltage and ripple endurance.
• General Purpose Filtering — General-purpose electrolytic duties in circuits requiring 250 V rating and a 150 µF value with polarized radial mounting.

Unique Advantages

• High ripple tolerance: 1.5 A at 100 kHz and 750 mA at 120 Hz give designers clear, frequency-specific ripple capability for real-world power circuits.
• Long operational life: 12,000 hours at 105°C provides a predictable endurance profile for sustained thermal and electrical stress.
• Compact radial form factor: φ18 × 30.5 mm can size with 7.5 mm lead spacing fits tight PCB layouts while keeping through-hole mounting simplicity.
• Measurable electrical limits: Specified tan δ, leakage-current formula (0.04CV + 100 µA), and tolerance give engineers verifiable parameters for margin and reliability calculations.
• RoHS compliant: Meets European RoHS requirements for material compliance.

Why Choose UCA2E151MHD?
