UBT1E332MHD8

The UBT1E332MHD8 is a radial-lead aluminum electrolytic capacitor offering 3300 µF capacitance at a 25 V rating in a compact φ18 × 30.5 mm can. Designed for demanding environments, it provides high ripple handling and long-term endurance for applications where stable bulk energy storage and durability are required.

With an operating range from −40°C to 125°C and a 10,000 hour endurance at 125°C, this AEC-Q200 rated part addresses high-temperature, high-reliability designs while maintaining low impedance and controlled dissipation factor.

Key Features

• Capacitance & Voltage — 3300 µF (3.3 mF) nominal capacitance rated at 25 V for substantial bulk energy storage in through-hole assemblies.
• High-Temperature Endurance — Specified lifetime of 10,000 hours at 125°C, supporting long-term operation in elevated-temperature environments.
• Ripple Current Capability — Low-frequency ripple current of 2.218 A at 120 Hz and high-frequency ripple current of 3.31 A at 100 kHz to support power supply smoothing and transient loads.
• Low Impedance & Dissipation — Impedance of 17 mΩ and tanδ (DF) of 0.18 measured at 20°C, 120 Hz for predictable AC performance.
• Reliability & Qualification — AEC-Q200 rating for use in regulated, high-reliability segments.
• Mechanical & Mounting — Radial lead can with φ18 × 30.5 mm body and 7.5 mm lead spacing (±0.5 mm) for straightforward through-hole placement.
• Electrical Tolerance & Leakage — Capacitance tolerance −20% to +20% and leakage current 2475 µA for design-level budgeting.
• Packaging & Availability — Available in bulk (no terminal forming) and bag packing; product is in mass production and RoHS compliant.

Typical Applications

• Automotive power electronics — Bulk energy storage and smoothing in vehicle power supplies where high ripple handling and 125°C endurance are required.
• DC–DC converters and regulators — Output and intermediate filtering where high capacitance and low impedance reduce voltage ripple under dynamic loads.
• Power modules and control units — Decoupling and energy buffering in control electronics that must tolerate elevated temperatures and continuous operation.

Unique Advantages

• Large capacitance in a compact can: 3300 µF at 25 V in a φ18 × 30.5 mm radial can provides significant energy density for space-constrained through-hole designs.
• High ripple handling: Rated ripple currents of 2.218 A (120 Hz) and 3.31 A (100 kHz) support both low- and high-frequency power filtering requirements.
• Designed for high-temperature service: 10,000 hour life at 125°C and operation down to −40°C enable deployment in thermally demanding environments.
• Low impedance and controlled dissipation: 17 mΩ impedance and a tanδ of 0.18 (20°C, 120 Hz) provide predictable AC behavior for stability and thermal management.
• AEC-Q200 rated: Qualification for applications requiring automotive-grade reliability.
• Simple through-hole implementation: Radial lead layout with defined 7.5 mm lead spacing eases PCB layout and assembly for legacy and robust connectorized designs.
