Key Features
- 47 µF capacitance at 10 V DC rating suits decoupling and bulk energy storage in low-voltage switching power supplies and LDO output filters
- 1000-hour rated endurance at 105°C operating temperature ensures long service life in thermally demanding industrial and consumer applications
- Compact 5 mm diameter by 5.4 mm height SMD body minimizes PCB footprint while maintaining high capacitance per unit area
- Panasonic HA series construction offers low ESR characteristics suitable for high-ripple-current applications in switch-mode power stages
Applications
The EEE-HA1A470WR is widely used as an output filter capacitor in DC-DC buck converters and LDO regulators powering 3.3 V and 5 V supply rails in consumer electronics, portable devices, and industrial control boards. Its 47 µF capacitance and 10 V rating make it ideal for smoothing ripple current on low-voltage power rails in smartphones, tablets, and smart home appliances. The 105°C rated endurance also qualifies it for use near heat-generating components in compact, thermally constrained enclosures.

Frequently Asked Questions
What capacitance and voltage rating does EEE-HA1A470WR carry, and which power rail voltages does it suit?
The EEE-HA1A470WR is rated at 47 µF and 10 V DC, making it suitable for smoothing output ripple on 3.3 V, 5 V, and lower supply rails commonly used in microcontrollers, FPGAs, and communication ICs. Designers typically apply it on rails with actual voltages at least 20 percent below the rated 10 V to extend capacitor service life.
What is the EEE-HA1A470WR's lifetime rating, and how does this affect design decisions for industrial equipment?
The EEE-HA1A470WR is rated for 1000 hours at 105°C ambient temperature. For industrial equipment operating at lower temperatures such as 85°C, the Arrhenius rule typically doubles expected lifetime for every 10°C reduction, projecting service life well beyond 4000 hours and making it a practical choice for control panels and metering devices with multi-year service expectations.
How do the physical dimensions of EEE-HA1A470WR affect PCB layout for SMT assembly?
The EEE-HA1A470WR measures 5 mm in diameter and 5.4 mm in height as a surface mount component. This compact cylindrical SMD footprint suits automated pick-and-place assembly and fits within standard clearance envelopes for consumer electronics enclosures, requiring a land pattern pad diameter slightly larger than 5 mm and minimum component clearance of 0.5 mm to adjacent parts.
When should a designer choose EEE-HA1A470WR over a ceramic multilayer capacitor for output filtering?
A designer should choose the EEE-HA1A470WR when 47 µF of capacitance is needed at 10 V and cost is a priority, as aluminum electrolytic capacitors offer significantly lower cost per µF than equivalent MLCC capacitors in this range. However, the EEE-HA1A470WR has higher ESR than Class II ceramics, so for load transients faster than 1 µs, a parallel 100 nF MLCC is recommended to handle high-frequency ripple components.
