What are the key features of EEE-1HA4R7SR?
- 4.7 µF / 50 V SMD aluminum electrolytic capacitor optimized for surface-mount reflow assembly
- ±20% capacitance tolerance with stable low-ESR characteristics for power supply filtering
- Compact surface-mount package enabling high-density PCB designs in consumer and industrial electronics
- Full reel tape packaging (paper/embossed) for seamless automated pick-and-place assembly
What is EEE-1HA4R7SR used for?
The Panasonic EEE-1HA4R7SR is used in bulk energy storage and power supply decoupling on switching regulators, DC-DC converters, and motor driver boards operating from 12 V to 48 V rails. Its 50 V rating provides ample headroom in 24 V industrial power supplies and LED driver circuits where transient voltage spikes can exceed the nominal rail. The SMD footprint and full reel packaging make it ideal for high-volume automated PCB manufacturing in consumer electronics and smart home devices.

Frequently Asked Questions
What capacitance and voltage rating does the EEE-1HA4R7SR offer for power supply filtering?
The EEE-1HA4R7SR provides 4.7 µF capacitance with a 50 V voltage rating and ±20% tolerance. In a typical 24 V switching power supply, this capacitor offers sufficient bulk energy storage to suppress ripple voltages below 50 mV peak-to-peak on the output rail when used in combination with ceramic bypass capacitors.
How does the 50 V rating of EEE-1HA4R7SR benefit designs with 24 V or 36 V power rails?
A 50 V rated capacitor provides a 2× derating margin when used on a 24 V rail, and approximately 1.4× on a 36 V rail. This headroom protects against transient overvoltages of up to 14 V on a 36 V bus, extending capacitor operational life beyond 2000 hours at 105°C by reducing dielectric stress during startup surges.
Can the EEE-1HA4R7SR be assembled with standard SMT reflow processes, and what tape format does it ship in?
Yes, the EEE-1HA4R7SR is a surface-mount device designed for reflow soldering and is supplied in full reel tape format compatible with standard pick-and-place machines. The embossed tape pockets securely hold individual capacitors, supporting high-speed automated assembly at rates exceeding 10,000 placements per hour without jamming or misfeeds.
When is 4.7 µF at 50 V preferable to a 10 µF ceramic capacitor in a DC-DC converter output stage?
Aluminum electrolytic capacitors like EEE-1HA4R7SR maintain their 4.7 µF capacitance value under 50 V DC bias, while multi-layer ceramic capacitors (MLCCs) rated at 10 µF/50 V can lose 60–80% of capacitance under full DC bias, effectively dropping to 2–4 µF. For applications requiring stable capacitance at high voltage, the EEE-1HA4R7SR offers more predictable filter performance per dollar.
