Frequently Asked Questions
What is the maximum operating temperature of ECEC1CA103BJ and how does it affect lifetime?
The ECEC1CA103BJ is rated to +105°C maximum, which doubles the expected service life compared to standard 85°C-rated aluminum electrolytic capacitors. Operating continuously at 105°C provides roughly 1000 to 2000 hours of rated lifetime, while cooler environments of 25°C can extend this to tens of thousands of hours, making thermal derating a key design consideration.
Which power supply topologies benefit most from the 10000µF capacitance of ECEC1CA103BJ?
Linear regulated power supplies and full-wave bridge rectifier stages benefit most from this 10000µF, 16V capacitor. The large capacitance reduces output ripple voltage below 50mV at load currents up to several amperes, while the 22mm x 30mm radial through-hole package simplifies PCB layout for traditional transformer-based designs.
How does the 1.2mA leakage current of ECEC1CA103BJ compare to film capacitors for low-power standby circuits?
At 1.2mA maximum DC leakage, the ECEC1CA103BJ draws significantly more quiescent current than film or ceramic capacitors, which typically leak below 1µA. For standby circuits powered from a 16V bus, this 1.2mA leakage represents up to 19mW of continuous dissipation, making film capacitors preferable for ultra-low-power applications but leaving aluminum electrolytics optimal for high-capacitance bulk storage.
