Key Features
- 22 µF capacitance at 35 V DC rating providing robust bulk energy storage on medium-voltage power rails up to 35 V
- Ultra-low leakage current of 0.0077 mA minimizing standby power loss in battery-powered and energy-efficient designs
- Surface-mount FK series construction with RoHS and REACH compliance enabling automated lead-free reflow soldering assembly
Applications
EEEFK1V220R is designed for output bulk decoupling and ripple filtering on 12 V to 24 V DC power rails in industrial automation, networking equipment, and LED driver circuits. Its 35 V rating and 22 µF capacitance suit intermediate bus converter output filtering and holdup capacitance in mid-voltage power stages. The low leakage current of 0.0077 mA also makes it suitable for battery-backed power management circuits where minimizing self-discharge is important.

Frequently Asked Questions
What capacitance and voltage rating does EEEFK1V220R provide for mid-voltage power supply filtering?
EEEFK1V220R is rated at 22 µF capacitance with a 35 V DC working voltage, making it appropriate for bulk decoupling on 12 V, 15 V, and 24 V power rails with standard 50–80% voltage derating practice. The 22 µF value effectively smooths ripple in switching regulator outputs operating at 100 kHz to 500 kHz, maintaining stable rail voltage under transient load steps in industrial and networking power supplies.
How does EEEFK1V220R's leakage current specification benefit energy-efficient and battery-powered designs?
EEEFK1V220R specifies a maximum leakage current of only 0.0077 mA at 35 V, which translates to less than 0.27 mW of standby power loss per capacitor. In battery-backed power management circuits and sleep-mode power rails for IoT gateways, this low leakage preserves battery charge during extended idle periods, contributing to multi-month or multi-year operational life when combined with microcontroller deep-sleep modes.
In a 24 V industrial control board design, how does EEEFK1V220R's 5.8 mm height affect component placement near connectors?
At 5.8 mm tall, EEEFK1V220R is a moderately tall SMD aluminum electrolytic component that must be placed away from connectors and board edge-mounted headers with low clearance height constraints. On standard 24 V industrial PCBs with heatsinks or DIN rail enclosures that accommodate 8–10 mm component heights, EEEFK1V220R fits comfortably while providing 22 µF of bulk capacitance for 24 V rail stabilization near power input connectors.
How does Panasonic FK series EEEFK1V220R compare to tantalum capacitors for 22 µF at 35 V in PCB cost-sensitive designs?
A 22 µF, 35 V tantalum capacitor in a similar SMD package typically costs several times more per unit than EEEFK1V220R and carries a risk of short-circuit failure mode under voltage surge conditions. EEEFK1V220R as an aluminum electrolytic is lower cost, fails open rather than short in most surge scenarios, and offers 35 V rating with ±20% capacitance tolerance, making it a more economical and failure-safe choice for bulk decoupling on industrial 24 V power buses.
