• Temperature Range & Endurance: Rated for −55 °C to 105 °C with a published life of 1000 hours at 105 °C.
• Ripple Current Performance: Low-frequency ripple current 1.71 A at 120 Hz and high-frequency ripple current 1.966 A at 10 kHz, supporting demanding AC ripple loads.
• Loss and Leakage: Tangent of loss angle (tan δ) specified at 0.24 (measured at 20 °C, 120 Hz, 25 V) with measured leakage current of 3525 µA.
• Package & Mounting: Radial lead (can) package, case size φ16 × 30.5 mm, lead spacing 7.5 mm (tolerance ±0.5 mm), suitable for through-hole mounting.
• Reliability & Ratings: AEC-Q200 rated and produced for mass production; packaging available as bulk (no terminal forming) or bag packing.
• Polarized Device: Polar electrolytic construction for correct orientation in DC circuits.

Typical Applications

• Audio Power Supplies: Bulk smoothing and reservoir capacitance for audio amplifiers and preamplifiers to maintain stable rails under dynamic load.
• Power Filtering: Input/output filtering and decoupling in DC power supply modules where high capacitance and ripple handling are required.
• Industrial Electronics: Energy storage and ripple suppression in control equipment and power conditioning modules operating across a wide temperature range.

Unique Advantages

• High Bulk Capacitance: 4700 µF provides substantial energy storage for smoothing and transient support, reducing the need for parallel components.
• Wide Temperature Operation: −55 °C to 105 °C rating enables deployment in systems exposed to broad ambient conditions.
• Strong Ripple Capability: Specified low- and high-frequency ripple currents support both mains-frequency and switching-power applications.
• Durability Confirmed by Endurance: 1000-hour rating at 105 °C gives a predictable life profile for thermal-stressed designs.
• AEC-Q200 Rating: Conformance to AEC-Q200 provides an added level of component qualification for designs that require recognized reliability standards.
• Practical Through-Hole Form Factor: Radial lead, φ16 × 30.5 mm can and standard 7.5 mm lead spacing simplify PCB layout and mechanical mounting.
