Key Features

• Capacitance and Voltage — 3300 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance, providing substantial bulk capacitance for power rail stabilization.
• Ripple Current Performance — Low-frequency ripple current of 1.4 A (120 Hz) and high-frequency ripple current of 1.61 A (10 kHz), supporting continuous AC loading on audio power supplies.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.22 measured at 20 °C, 120 Hz, suitable for applications where dissipation factor is a consideration.
• Leakage and Endurance — Specified leakage current of 2475 µA and endurance rated for 2000 hours at 105 °C, enabling reliable long-term operation under elevated temperature stress.
• Wide Temperature Range — Rated for -55 °C to 105 °C to accommodate a broad range of environmental conditions encountered in professional audio equipment.
• Package and Mounting — Radial lead can with case size φ12.5 × 35.5 mm and 5 mm lead spacing (±0.5 mm), available in bulk or bag packing for through‑hole assembly.
• Quality Standard — Series includes AEC-Q200 rating, reflecting qualification to an established reliability standard for passive components.

Typical Applications

• Audio — Power supply bulk capacitance: Provides 3300 µF at 25 V for energy storage and voltage smoothing in audio amplifiers and high‑grade audio equipment.
• Audio — Ripple handling: Rated ripple currents (1.4 A at 120 Hz, 1.61 A at 10 kHz) address both low‑ and high‑frequency ripple in audio power rails.
• Audio — Harsh environments: Wide -55 °C to 105 °C operating range and 2000 h endurance at 105 °C support reliable operation in professional installation and field equipment.

Unique Advantages

• High bulk capacitance: 3300 µF provides substantial energy reserve to reduce voltage sag during peak audio demands.
• Robust ripple capability: Measured ripple ratings at both 120 Hz and 10 kHz help ensure stable performance across audio-relevant frequency ranges.
• Wide thermal tolerance: Operation from -55 °C to 105 °C enables use across studio, live‑sound, and installed audio environments.
• Proven endurance: 2000 hours at 105 °C endurance rating supports long-term reliability in elevated-temperature applications.
• Radial lead format: Through‑hole radial can (φ12.5 × 35.5 mm) with 5 mm lead spacing simplifies replacement and prototyping in conventional PCB layouts.
• Industry reliability standard: Inclusion of AEC‑Q200 in the series provides an added layer of component reliability verification for conservative designs.
