## Description
The Eaton KR-5R5V334-R is a vertical-mount electric double-layer capacitor (EDLC) designed for high-reliability energy storage and power backup applications. This 0.33F supercapacitor operates at a maximum working voltage of 5.5V DC, with a surge voltage rating of 6.3V. The component features a nominal capacitance tolerance of -20% to +80% and an initial equivalent series resistance (ESR) of 50Ω measured at 1kHz. Packaged in a compact coin-style form factor with a 11.5mm diameter and 12.7mm height, this device utilizes through-hole PC pin terminals with a 5mm lead spacing for secure PCB integration.
Engineered for longevity and performance, the KR-5R5V334-R supports an operating temperature range of -25°C to +70°C, with a rated lifetime of 1000 hours at maximum temperature and voltage. Its low leakage current and high power density make it an effective solution for real-time clock (RTC) backup, utility meters, HVAC controls, and power buffering in computer peripherals or network equipment. The component is RoHS compliant and halogen-free, ensuring compatibility with modern environmental standards. When assembling, wave soldering is recommended within specified thermal profiles, while manual soldering should be performed with caution to avoid thermal damage to the external sleeve and to maintain the integrity of the internal ESR characteristics.

## **Manual solder**
Do not touch the supercapacitor’s external sleeve with the soldering rod or the sleeve will melt or crack. The recommended temperature of the soldering rod tip is less than 260 °C (maximum: 350 °C) and the soldering duration should be less than 5 seconds. Minimize the time that the soldering iron is in direct contact with the terminals of the supercapacitor as excessive heating of the leads may lead to higher equivalent series resistance (ESR).
## **Reflow soldering**
Do not use reflow soldering using infrared or convection oven heating methods.
## **Cleaning/Washing**
Avoid cleaning of circuit boards, however if the circuit board must be cleaned use static or ultrasonic immersion in a standard circuit board cleaning fluid for no more than 5 minutes and a maximum temperature of +60 °C. Afterwards thoroughly rinse and dry the circuit boards. In general, treat supercapacitors in the same manner you would an aluminum electrolytic capacitor.
