Applications
The EEE-0JA470WR is designed for decoupling and bulk energy storage in portable consumer electronics, smartphones, tablets, and low-power IoT devices operating from 3.3V to 5V regulated rails. Its 47µF capacitance smooths voltage ripple at switching regulator outputs and provides hold-up energy during brief load transients. The compact 4mm diameter SMD package enables dense placement near power delivery ICs on multilayer PCBs in space-constrained handheld and wearable products.

Frequently Asked Questions
How does the 36mA ripple current rating of the EEE-0JA470WR determine its suitability for switching regulator output filtering?
The 36mA maximum ripple current rating defines the AC current the capacitor can handle continuously without exceeding its internal ESR heating limits. For typical low-power DC-DC converters operating at 100kHz to 1MHz with output currents below 500mA, the capacitor ripple current is usually well below 36mA, making EEE-0JA470WR appropriate as a single output filter capacitor in 3.3V or 5V regulated supplies for IoT and portable applications.
What is the expected service life of the EEE-0JA470WR in a consumer electronics design running at 5V?
The capacitor is rated for 1000 hours at its 6.3V maximum rated voltage and maximum rated temperature. Operating at a derated 5V rail—approximately 79% of rated voltage—extends lifespan significantly, as electrolytic capacitor lifetime roughly doubles for every 10°C reduction below the rated temperature and for each 0.5V reduction below rated voltage. In typical consumer applications at 40°C to 50°C ambient, expected service life can reach 5000 to 10000 hours.
Can the EEE-0JA470WR 4mm × 5.4mm SMD package be placed using standard reflow soldering in high-volume production?
Yes, the 4mm diameter cylindrical SMD package uses standard aluminum electrolytic reflow-compatible terminations and fits standard IPC land patterns, allowing placement by pick-and-place machines at production rates comparable to other passive SMD components. The package height of 5.4mm must be verified against component clearance requirements, particularly on double-sided boards or assemblies with height restrictions below 6mm.
