Key Features
- 50 V rated with 10 µF capacitance in a miniature 5 mm × 5.4 mm body, delivering excellent volumetric efficiency for PCB-space-limited designs
- Ultra-low leakage current of 0.005 mA preserves charge accuracy in sample-and-hold, ADC bypass, and energy-harvesting node applications
- 1,000-hour lifetime at 105°C ensures robust performance in industrial and automotive-adjacent power supply designs with elevated ambient temperatures
- RoHS and REACH compliant lead-free construction satisfies modern environmental regulations for global product distribution
Applications
EEE1HA100WAR is used as a bypass and bulk decoupling capacitor on 24 V to 48 V supply rails in industrial sensor modules, SMPS output stages, and motor control driver boards where a compact 5 mm diameter radial capacitor with 50 V rating is required. Its ultra-low leakage current of 0.005 mA makes it appropriate for timer-RC circuits, sample-and-hold networks, and precision ADC reference filtering where charge retention over milliseconds is critical. The Panasonic S(V) series construction also maintains stable capacitance across -40°C to 105°C for reliable all-season operation.

Frequently Asked Questions
How does the 0.005 mA leakage current specification of EEE1HA100WAR affect its use in a precision timer or sample-and-hold circuit at 50 V?
With only 0.005 mA leakage at 50 V, EEE1HA100WAR will discharge a 10 µF capacitor at a rate of 0.5 V per second when fully charged. In a sample-and-hold circuit with a 10 ms hold time, this causes a droop of 5 mV — negligible for 12-bit ADC systems with 12.2 mV LSB at 50 V full scale. This exceptionally low leakage is well below the 0.02 mA to 0.1 mA typical for general-purpose aluminum electrolytics of the same value.
What physical dimensions does EEE1HA100WAR have, and can it fit a standard 5 mm lead-pitch footprint on an existing PCB?
EEE1HA100WAR measures 5 mm diameter by 5.4 mm body height with a standard 2.0 mm lead pitch. This is a common footprint used for D-series radial capacitors, so the component drops directly into PCB land patterns with 2.0 mm hole spacing without layout changes. Its 5 mm diameter also fits alongside components with 6.3 mm or 8 mm diameter capacitors on the same board without mechanical interference.
For an industrial IoT sensor board running at 24 V, how long should EEE1HA100WAR last before capacitance falls below 80% of its initial 10 µF value?
EEE1HA100WAR is rated for 1,000 hours at 105°C. Applying the Arrhenius rule with a doubling per 10°C step, operation at 65°C ambient (typical for a board inside an IoT enclosure at 24 V) extends the lifetime to approximately 16,000 hours, or roughly 2 years of continuous operation. For a 10-year product design life target, operating below 45°C or selecting a 2,000-hour or 5,000-hour series capacitor from Panasonic would be required.
How does EEE1HA100WAR compare to a 10 µF X5R ceramic MLCC at 50 V for switching regulator output filtering?
A 10 µF 50 V X5R MLCC in 1210 package retains less than 50% of its capacitance at 50 V DC bias due to voltage coefficient effects, effectively delivering only 4 to 5 µF under operating conditions. EEE1HA100WAR maintains 10 µF within ±20% at full rated 50 V. However, the aluminum electrolytic has higher ESR — typically 5 to 15 ohms at 100 kHz — making it unsuitable as the sole output capacitor for converters above 200 kHz without a parallel low-ESR ceramic. For sub-100 kHz designs the electrolytic remains cost-effective and dimensionally efficient.
