Frequently Asked Questions
What are the key electrical ratings of the Panasonic EEE-HA1V4R7R aluminum electrolytic capacitor?
The EEE-HA1V4R7R is rated at 4.7 µF capacitance, 35 V working voltage, and ±20% tolerance. These ratings make it suitable for bulk decoupling on power rails up to 35 V in SMD switching power supplies, LED drivers, and industrial sensor conditioning circuits.
For a 24 V DC-DC converter output filter, does the 35 V rating of EEE-HA1V4R7R provide adequate voltage margin?
Yes, the EEE-HA1V4R7R rated at 35 V provides approximately 46% voltage headroom above a 24 V rail, which meets the common industry guideline of derating aluminum electrolytic capacitors to 80% of rated voltage. The 4.7 µF capacitance also contributes adequate energy storage for output ripple filtering in DC-DC converter designs.
How does the ±20% tolerance of the EEE-HA1V4R7R affect circuit design for power filtering?
The ±20% tolerance means the 4.7 µF EEE-HA1V4R7R can range from 3.76 µF to 5.64 µF in production. For power rail decoupling, this variance is generally acceptable since filter corner frequencies shift by less than 25%, but designers should verify ripple voltage margins across the full tolerance band, especially in noise-sensitive analog circuits.
What procurement advantage does the full reel format of EEE-HA1V4R7R offer over cut tape for manufacturing?
Ordering the EEE-HA1V4R7R on full reel (typically 1000 to 2000 pieces per reel) reduces per-unit cost and eliminates reel splicing setup time on SMT lines. Full reel also ensures all 4.7 µF, 35 V capacitors in a production batch come from the same lot code, simplifying traceability and quality control audits.
