Frequently Asked Questions
What are the key electrical ratings of the Panasonic EEE-FK1K101AQ capacitor?
The EEE-FK1K101AQ is rated at 100 µF capacitance with an 80 V DC voltage rating. It belongs to Panasonic's FK Series of high-temperature SMD aluminum electrolytic capacitors, designed to withstand reflow soldering up to 260°C peak and long-term operation at 105°C ambient temperature.
How does the EEE-FK1K101AQ perform in switch-mode power supply designs requiring 80 V bulk capacitance?
In SMPS designs, the EEE-FK1K101AQ provides 100 µF at 80 V DC, offering effective bulk energy storage and voltage ripple filtering at frequencies from 120 Hz to several kHz. Its low ESR characteristic and SMD form factor reduce parasitic inductance, improving overall power conversion efficiency and reducing output ripple voltage.
What package style does the EEE-FK1K101AQ use, and how does this affect PCB layout?
The EEE-FK1K101AQ uses an SMD (surface-mount) aluminum electrolytic package compatible with standard reflow soldering processes at peak temperatures up to 260°C. The radial SMD footprint requires adequate pad spacing on the PCB to accommodate the capacitor body and ensure proper electrical contact across the 80 V rated terminals.
When would an engineer select the EEE-FK1K101AQ over a standard temperature aluminum electrolytic capacitor?
Engineers choose the FK Series EEE-FK1K101AQ when designs operate at ambient temperatures above 85°C, reach 105°C, or require reflow soldering compatibility. Applications such as industrial motor drives, telecom power supplies, and automotive-adjacent electronics benefit from its extended temperature tolerance at 100 µF and 80 V compared to standard-grade aluminum electrolytics.
