Frequently Asked Questions
What capacitance and voltage rating does the EEE-HB1HR33AR provide?
The EEE-HB1HR33AR is rated at 0.33 µF capacitance with a 50 V maximum voltage rating, making it suitable for medium-voltage decoupling and bypass tasks in SMD circuit designs. Its HB series construction delivers low leakage current, which extends operational life in continuously powered consumer and industrial electronics.
Over what temperature range is the EEE-HB1HR33AR specified for reliable operation?
Panasonic rates this capacitor for operation from -40°C to +105°C, covering the full industrial temperature range. The 105°C upper limit allows installation near power-dissipating components such as voltage regulators and motor drivers without significant degradation of the 0.33 µF capacitance value over time.
How does the EEE-HB1HR33AR compare to ceramic capacitors for decoupling a 50 V rail?
Unlike ceramic capacitors, the EEE-HB1HR33AR maintains a stable 0.33 µF capacitance across the full 50 V range without the strong DC-bias derating common in Class II MLCC dielectrics, which can lose 50% or more of capacitance at rated voltage. This makes the aluminum electrolytic more predictable for bulk decoupling at voltages above 25 V in power supply output stages.
