• Ripple Current Capability: Low-frequency ripple current of 3.45 A at 120 Hz and high-frequency ripple current of 3.9675 A at 10 kHz (frequency measurement conditions provided in datasheet).
• Electrical Loss and Leakage: Specified tangent of loss angle (tan δ) of 0.84 (measured at 20°C, 120 Hz) and a leakage current of 15,840 µA.
• Mechanical & Mounting: Radial lead can package, φ25 × 50 mm dimensions, lead spacing 12.5 mm (±0.5 mm), and available in bulk (no terminal forming) or bag packing.
• Compliance: RoHS compliant.
• Product Status: End Of Life.

Typical Applications

• General-purpose electronic circuits: Provides large bulk capacitance for circuits that require 33,000 µF at a 16 V rating and wide temperature tolerance.
• Power supply energy storage: Suited to low-voltage power rails where high capacitance and specified ripple current ratings are required.
• Industrial and control electronics: Useful where extended temperature range (-55°C to +105°C) and 2000-hour endurance at elevated temperature are needed.
• Consumer and commercial equipment: Applicable when a high-value electrolytic capacitor in a radial can (φ25 × 50 mm) is needed for general-purpose designs.

Unique Advantages

• Large bulk capacitance in a compact can: 33,000 µF delivered in a φ25 × 50 mm radial package minimizes board area for high-capacity requirements.
• Wide operating temperature range: -55°C to +105°C rating supports deployment across a broad set of environmental conditions.
• Defined endurance specification: 2000 hours at 105°C provides clear lifecycle expectations for thermal stress scenarios.
• Measured ripple performance: Specified ripple current figures for 120 Hz and 10 kHz give designers quantifiable parameters for thermal and ripple management.
• RoHS compliance: Meets environmental substance restrictions for regulated markets.
