Key Features
- 560 µF at 50V in a surface mount aluminum electrolytic package rated for 260°C peak reflow, enabling lead-free SMT assembly without special soldering profiles
- FK Series high-temperature reflow design maintains capacitance stability and electrolyte integrity after repeated reflow cycles, reducing field failure rates in automotive and industrial electronics
- Compact SMD footprint integrates large-value bulk capacitance directly onto densely populated PCBs without the board area penalty of through-hole radial electrolytic alternatives
Applications
The EEE-FK1H561AM is designed for output bulk filtering and energy storage in SMT switching power supplies, DC-DC converters, and motor controller gate driver circuits operating at up to 50V. Its high-temperature reflow compatibility and 560 µF capacitance make it a practical choice for automotive infotainment power rails, industrial servo drives, and LED driver modules where large-value SMD capacitance and process-compatible soldering are both required.

Frequently Asked Questions
What capacitance and voltage rating does the Panasonic EEE-FK1H561AM provide?
The EEE-FK1H561AM is rated at 560 µF and 50V DC working voltage. This combination delivers substantial bulk energy storage for output filter stages in switching regulators and DC bus circuits operating from 12V to 48V supply rails with adequate voltage derating for long-term reliability.
Why is the EEE-FK1H561AM's high-temperature reflow compatibility important for manufacturing?
The FK series is engineered to survive peak reflow temperatures up to 260°C, meeting lead-free J-STD-020 profile requirements. This allows the 560 µF SMD capacitor to pass through standard reflow ovens alongside other components without electrolyte venting or capacitance degradation, simplifying mixed-component PCB assembly in automotive and industrial production lines.
How does the SMD package of the EEE-FK1H561AM benefit high-density PCB layouts compared to radial through-hole alternatives?
The surface mount footprint of the EEE-FK1H561AM eliminates the need for through-board drilled holes, freeing inner PCB layers for signal routing. Placing 560 µF directly on the surface also shortens the current loop between the capacitor and the load, reducing parasitic inductance and improving high-frequency ripple attenuation in compact DC-DC converter outputs.
In which end-product categories is the Panasonic EEE-FK1H561AM FK series most commonly specified?
The EEE-FK1H561AM sees specification in automotive infotainment power management, industrial servo amplifiers, and telecom rectifier modules where 50V SMD electrolytic capacitors with 560 µF values and high-temp reflow ratings are standard requirements. It also appears in HVAC inverter boards and LED street lighting drivers that demand long operational lifetimes above 85°C ambient.
