What are the key features of ECEA1HKS2R2?
- 2.2µF at 50V in a compact 4mm diameter radial leaded package for space-efficient decoupling and filtering
- Ultra-low leakage current of 0.003mA minimizes standby power loss in battery-sensitive applications
- RoHS and REACH compliant (JESD-609 e3) aluminum wet electrolytic construction for use in regulated consumer and industrial products
What is ECEA1HKS2R2 used for?
The Panasonic ECEA1HKS2R2 is suited for power supply decoupling, bypass filtering, and energy storage in consumer electronics, audio equipment, and industrial control boards where a 50V rated 2.2µF capacitor in a 4mm radial package is required. Its low 0.003mA leakage current makes it particularly effective in battery-powered IoT sensors, portable medical monitors, and low-standby-current power management circuits where quiescent drain must be minimised.

Frequently Asked Questions
What are the key electrical parameters of the ECEA1HKS2R2 electrolytic capacitor?
The ECEA1HKS2R2 is a 2.2µF aluminum wet electrolytic capacitor rated at 50V with ±20% capacitance tolerance. Its leakage current is specified at 0.003mA, and the 4mm diameter radial package makes it straightforward to mount on standard through-hole PCB footprints used in power supply and signal filtering designs.
How does the 0.003mA leakage current of the ECEA1HKS2R2 compare to typical aluminum electrolytic capacitors in battery-powered designs?
The ECEA1HKS2R2's leakage current of 0.003mA (3µA) is at the low end for aluminum wet electrolytic capacitors in the 2.2µF, 50V class, which typically specify leakage up to 0.01mA or more. In a battery-powered device drawing 10mA total, this 3µA contributes less than 0.03% overhead, making the ECEA1HKS2R2 a suitable choice for low-standby-current IoT sensors and portable instruments.
Which PCB assembly considerations apply when using the 4mm diameter radial package of the ECEA1HKS2R2?
The ECEA1HKS2R2 uses a 4mm diameter radial leaded through-hole package, so the PCB must include two plated-through holes on a standard 2mm lead pitch. The component height must also be checked against any chassis or cover clearance — typical radial electrolytic capacitors of 2.2µF 50V class are 7mm to 11mm tall, so height-constrained designs should verify the exact datasheet dimension before finalizing the board stack-up.
What is the typical application for a 2.2µF 50V capacitor like the ECEA1HKS2R2, and are there ceramic alternatives?
A 2.2µF 50V capacitor is commonly used for bulk decoupling on 12V to 48V DC-DC converter outputs, output filtering on linear regulators, and hold-up in low-power sensor circuits. Ceramic X7R capacitors of the same value at 50V are available in 0805 or 1206 SMT packages and offer lower ESR and longer service life, but typically cost 2 to 5 times more per unit than the ECEA1HKS2R2 in volume pricing, making the aluminum electrolytic the preferred choice when cost is the primary driver.
