What are the key features of EEE-1EA3R3NR?
- Bi-polar (non-polarized) construction allows capacitor to be used in AC coupling and audio circuits without polarity constraints
- 3.3 µF capacitance at 25 V rating from Panasonic VS series with low ESR for signal integrity
- SMD surface-mount package for automated PCB assembly and compact board layouts
- RoHS compliant materials for use in lead-free manufacturing processes
- Wide operating temperature range for industrial and consumer electronics applications
What is EEE-1EA3R3NR used for?
The EEE-1EA3R3NR is well-suited for AC coupling capacitor roles in audio amplifier input and output stages, crossover networks, and signal conditioning circuits where bipolar operation eliminates the need for correct polarity orientation during assembly. It is also used in motor driver circuits, servo feedback paths, and AC power supply filtering where non-polarized capacitors of 3.3 µF at 25 V are required. The SMD package facilitates high-volume automated manufacturing in consumer electronics, home audio equipment, and industrial control boards.

Frequently Asked Questions
Why is EEE-1EA3R3NR a bipolar capacitor and when should it be used instead of a standard polarized electrolytic?
EEE-1EA3R3NR is a bi-polar (non-polarized) aluminum electrolytic capacitor, meaning it operates correctly regardless of voltage polarity across its terminals. This is essential in AC coupling paths, audio crossover networks, and motor feedback circuits where the signal alternates polarity, making a polarized 3.3 µF capacitor unsuitable.
What are the rated capacitance and voltage of EEE-1EA3R3NR for filter design calculations?
EEE-1EA3R3NR is rated at 3.3 µF capacitance and 25 V maximum working voltage. In an RC high-pass filter with a 10 kΩ resistor, this capacitor sets a -3 dB cutoff frequency of approximately 4.8 Hz, making it suitable for audio coupling and low-frequency signal conditioning applications.
How does the SMD package of EEE-1EA3R3NR benefit high-volume automated assembly processes?
The EEE-1EA3R3NR uses a standard SMD aluminum electrolytic package compatible with pick-and-place machine assembly and reflow soldering. The surface-mount format eliminates through-hole drilling costs, reduces PCB layer count requirements, and allows placement on both sides of the board, saving board space in consumer electronics and home audio designs.
What is the operating temperature range of EEE-1EA3R3NR and does it suit industrial environments?
EEE-1EA3R3NR from Panasonic's VS series is rated for operation from -40°C to 85°C, covering standard commercial and light industrial temperature ranges. This makes it appropriate for indoor industrial control equipment, audio amplifiers, and consumer electronics deployed in moderate ambient environments where 85°C rated capacitors are sufficient.
Can EEE-1EA3R3NR replace a film capacitor in an audio coupling stage, and what are the trade-offs?
EEE-1EA3R3NR can replace a film capacitor for AC coupling at audio frequencies up to 20 kHz, offering a much smaller SMD footprint and lower cost per µF compared to a 3.3 µF film capacitor. The trade-off is higher ESR and some capacitance variation with voltage, which may affect THD in high-fidelity amplifier stages where film capacitors with ESR below 0.1 Ω are preferred.
