Frequently Asked Questions
What are the capacitance and voltage rating of the EEE-HP1E3R3R?
The EEE-HP1E3R3R has a capacitance of 3.3 µF and a voltage rating of 25 V. These values make it suitable for decoupling low-voltage power rails in microcontroller and analog circuits, where compact size and SMD mounting are required for automated PCB assembly lines.
How does the 105°C temperature rating of the EEE-HP1E3R3R affect its suitability for industrial applications?
The 105°C maximum operating temperature rating allows the EEE-HP1E3R3R to maintain stable capacitance and low ESR in enclosures with limited airflow, such as industrial controllers, power converters, and automotive-adjacent equipment. Rated for 105°C, it can outlast standard 85°C-rated alternatives in thermally demanding environments, directly extending system service life.
Can the EEE-HP1E3R3R be used as an output filter capacitor in a 12 V to 5 V switching regulator?
Yes, however its 25 V maximum voltage rating comfortably handles a 5 V output rail with margin, but the 3.3 µF value is modest for heavy-load output filtering. For higher ripple current demands, placing multiple EEE-HP1E3R3R capacitors in parallel or combining with a 10 µF to 100 µF bulk capacitor improves ripple attenuation in a switching regulator operating at 100 kHz to 1 MHz.
