What is EEE-1VA4R7NR used for?
The EEE-1VA4R7NR is ideal for bulk decoupling and power supply output filtering on 3.3 V, 5 V, and 12 V rails in embedded systems, consumer electronics, and industrial control boards where 35 V rated capacitors provide adequate voltage margin. It is commonly placed at the output of DC-DC converters and LDO regulators to suppress ripple and reduce high-frequency noise on supply rails serving digital logic and microcontrollers. The compact SMD form factor allows placement near power pins in dense PCB layouts with minimal board area impact.

Frequently Asked Questions
What are the key electrical specifications of EEE-1VA4R7NR for power supply decoupling design?
EEE-1VA4R7NR is rated at 4.7 µF capacitance with a 35 V maximum working voltage and ±20% tolerance. In a typical DC-DC converter output filter, this capacitor works alongside a 10 µF bulk electrolytic and 100 nF ceramic bypass to attenuate switching ripple from several hundred mV to below 10 mV on a 5 V rail.
How does the 35 V rating of EEE-1VA4R7NR provide voltage margin in a 12 V power system?
With a 35 V voltage rating, EEE-1VA4R7NR provides approximately 2.9× voltage derating when used on a 12 V supply rail, well above the recommended 1.5× to 2× derating practice for electrolytic capacitors. This margin extends the capacitor's operational lifetime and improves reliability in 12 V automotive accessory and industrial power supply designs.
Is EEE-1VA4R7NR compatible with automated SMT assembly and lead-free soldering processes?
Yes. EEE-1VA4R7NR uses an SMD aluminum electrolytic package with surface-mount leads compatible with standard pick-and-place equipment and reflow soldering profiles up to 260°C per IPC J-STD-020. Its RoHS compliance ensures compatibility with lead-free solder alloys used in modern consumer electronics and industrial manufacturing lines.
When might a designer choose EEE-1VA4R7NR over a 4.7 µF MLCC ceramic capacitor for output filtering?
EEE-1VA4R7NR offers significantly lower cost per µF and better capacitance retention under DC bias compared to X5R or X7R MLCC ceramics at 4.7 µF, 35 V, which can lose 50–70% of nominal capacitance under a 35 V DC bias. For bulk output filtering at frequencies below 100 kHz where ESR is not critical, the electrolytic provides a cost-effective alternative.
What is the typical ESR of EEE-1VA4R7NR and how does it affect ripple current handling?
Panasonic VS series aluminum electrolytic capacitors at 4.7 µF, 35 V typically exhibit an ESR in the range of 5 to 15 Ω at 120 Hz, limiting their ripple current capability to approximately 20–50 mA RMS. For higher ripple current demands above 100 mA, designers typically parallel multiple units or combine with low-ESR polymer capacitors to meet filter requirements.
