UCS2W150MHD

The UCS2W150MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UCS series designed for high ripple current and long-term reliability. It provides 15 µF capacitance at a 450 V rating in a compact can package, optimized for power-supply and ballast applications as well as general-purpose high-voltage circuits.

Engineered for extended operation at elevated temperatures, this polarized capacitor is specified to operate from −40°C to +105°C and withstand a rated lifetime of up to 10,000 hours at +105°C under rated conditions.

Key Features

• Electrical Capacity: 15 µF capacitance at 450 V rated voltage, suitable for high-voltage filtering and decoupling.
• High Ripple Current: Rated ripple current of 300 mA at 120 Hz and 600 mA at 100 kHz, enabling robust handling of AC ripple in power circuits.
• Frequency Ripple Coefficients: Coefficients for ripple-current scaling are 0.40 (50 Hz), 0.50 (120 Hz), 0.80 (1 kHz), 0.90 (10 kHz) and 1.00 (100 kHz or more).
• Long-Life Endurance: Load-life performance specified for 10,000 hours at 105°C (endurance criteria: capacitance change within ±20% and tan δ up to 200% of initial).
• Temperature Range: Operates from −40°C to +105°C for wide environmental margin.
• Compact Radial Can Package: Radial lead, can-style package with lead spacing of 5 mm and physical size L: 2.5 × D: 1.25 cm, supporting ease of through-hole mounting and tight layouts.
• Polarized Construction & Tolerance: Polarized capacitor with tolerance of −20% to +20%.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Loss Angle (tan δ): Maximum tan δ for 450 V rating is 0.24 (measured at 120 Hz, 20°C), supporting predictable AC performance.

Typical Applications

• Power Supplies: Bulk filtering and smoothing in high-voltage switch-mode and linear power supplies where high ripple current capability and long life are required.
• Lighting Ballasts: AC ripple handling and long-term stability for ballast circuits in lighting applications.
• High-Voltage, General-Purpose Electronics: Decoupling and energy-storage roles in general-purpose high-voltage circuits that require a compact, radial-leaded solution.

Unique Advantages

• High ripple tolerance: Elevated ripple-current ratings at both low and high frequencies reduce stress on the capacitor and improve system reliability under AC loading.
• Extended high-temperature life: Specified 10,000-hour endurance at +105°C gives designers predictable long-term performance in hot environments.
• Compact high-voltage package: 15 µF at 450 V in a small radial can footprint enables space-efficient high-voltage designs.
• Clear performance limits: Defined tan δ and endurance criteria provide measurable acceptance limits for quality and reliability testing.
• RoHS compliance: Meets current RoHS requirements for environmentally regulated designs.
