• Rated Voltage and Tolerance: 16 V rated voltage with ±20% capacitance tolerance at 120 Hz, 20°C.
• Ripple Current Capability: Specified low-frequency ripple current of 1770 mA and high-frequency ripple current of 2170 mA to handle AC ripple in power circuits.
• Leakage Current: Product-level leakage current listed as 2256 µA.
• Endurance and Temperature Range: Rated for 2000 hours at 85°C with performance criteria of capacitance change within ±20% after the test; operating temperature range –40°C to +85°C.
• Compact Radial Package: φ18 can (φ18×20L referenced size) with 7.5 mm lead spacing and radial lead mounting for through-hole assembly; available in bulk (no terminal forming) or bag packing.
• Polarized Construction: Polar aluminum electrolytic design suitable for DC filtering and bulk decoupling in polarized circuits.
• Lifecycle Status: Product is currently listed as End Of Life; verify availability and lead-time prior to design commitment.

Typical Applications

• General-Purpose Electronics: Used where a 4700 µF, 16 V polarized electrolytic is required for bulk capacitance in power rails and general DC systems.
• Power Filtering and Smoothing: Applicable in power supply output filtering and energy-storage roles in small to medium power designs.
• Decoupling and Bulk Storage: Suitable for decoupling low-frequency fluctuations and providing local energy reserves in board-level designs.

Unique Advantages

• Large Capacitance in a Compact Can: 4700 µF in a φ18 package conserves PCB area while delivering substantial bulk capacitance.
• Designed for Elevated Temperature Endurance: Endurance rating of 2000 hours at 85°C with defined post-test limits helps predict long-term behavior under sustained thermal stress.
• Measurable Ripple Handling: Specified low- and high-frequency ripple currents (1770 mA / 2170 mA) enable designers to size the part for expected AC loads.
• Through-Hole Radial Mounting: Radial lead configuration and 7.5 mm lead spacing simplify manual assembly and prototyping.
• Clear Manufacturing Options: Available in bulk (no terminal forming) or bag packing to match manufacturing and inventory workflows.
• Series-Level Specification Support: Benefits from URS series documentation on stability, impedance, and endurance at rated conditions.
