Key Features

• Capacitance and Voltage – 3300 µF nominal capacitance at a rated voltage of 25 V, with a tolerance of −20% to +20% for predictable bulk energy storage.
• Low Impedance – Rated impedance of 40 mΩ supports lower ripple voltage and improved transient performance in power rails.
• High Ripple Current Capability – Supports 2.329 A at 120 Hz (low frequency) and 2.74 A at 10 kHz (high frequency), enabling effective smoothing in switching supplies and converters.
• Long Endurance at Elevated Temperature – Specified lifetime of 8000 hours at 105 °C, suitable for designs that require extended high‑temperature reliability.
• Wide Operating Temperature – Rated for −55 °C to 105 °C to cover demanding thermal environments.
• Measurement Characteristics – Tangent of loss angle (tan δ) specified at 0.14 (measured at 20 °C, 120 Hz, 25 V), and a measured leakage current of 2475 µA for this part.
• Compact Radial Package – φ18×25 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through‑hole assembly; available in bulk or bag packing.
• Qualification – AEC‑Q200 rating indicated in the product data for automotive applications.

Typical Applications

• Switching Power Supplies – Bulk and smoothing capacitor for DC filter stages where low impedance and high ripple current are required.
• Automotive Power Electronics – Suitable for vehicle electronic systems that require AEC‑Q200 qualified components and long endurance at elevated temperatures.
• DC‑DC Converters and Regulators – Energy reservoir and output filtering in converters operating across a wide temperature range.

Unique Advantages

• High ripple handling: Directly supported by specified ripple currents of 2.329 A (120 Hz) and 2.74 A (10 kHz), reducing stress on upstream components and smoothing supply rails.
• Low ESR/Impedance: 40 mΩ impedance helps minimize voltage ripple and thermal losses in power circuits.
• Extended high‑temperature life: 8000‑hour endurance at 105 °C provides long service life in thermally demanding designs.
• Automotive‑grade qualification: AEC‑Q200 rating supports use in automotive electronics where industry qualification is required.
• Compact through‑hole form factor: φ18×25 mm radial can with 7.5 mm lead spacing offers a space‑efficient solution for PCB layouts that prefer axial or radial through‑hole mounting.
• Production readiness: Listed as mass production with bulk/bag packaging options to support volume procurement and assembly.
