Frequently Asked Questions
What are the key electrical specifications of the UWX1A330MCL1GB capacitor?
The UWX1A330MCL1GB is a 33 µF aluminum electrolytic capacitor rated at 10 V with a leakage current of 0.0033 mA. Its 5.4 mm height and surface-mount package make it suitable for compact PCB designs where low-profile bulk decoupling at 10 V or below is required.
How does the low leakage current of UWX1A330MCL1GB benefit battery-powered designs?
With a leakage current of only 0.0033 mA, the UWX1A330MCL1GB draws negligible standby power compared to standard aluminum electrolytics. In a battery-powered device operating at 3.3 V to 10 V, this low leakage minimizes drain during sleep states, extending battery runtime by reducing parasitic losses across multiple 33 µF decoupling capacitors.
Can UWX1A330MCL1GB be used in DC-DC converter output filtering at switching frequencies above 100 kHz?
Wet aluminum electrolytic capacitors like the UWX1A330MCL1GB are generally effective at switching frequencies up to about 100 kHz before their equivalent series resistance (ESR) and internal inductance limit high-frequency ripple attenuation. For 33 µF bulk energy storage on a 10 V rail at moderate switching frequencies of 50 kHz to 100 kHz, this capacitor provides adequate filtering when paralleled with low-ESR ceramic capacitors for high-frequency bypassing.
