Electric Double Layer Capacitors

Product catalog summary

Overview: This document is a technical catalog for Electric Double Layer Capacitors, also known as Gold Capacitors, from 2020. It includes detailed application guidelines, specifications, and recommendations for use, mounting, and storage.

Application Guidelines:

Product Life: Capacitor life is influenced by ambient temperature, humidity, voltage, and discharging currents. Life expectancy ranges from 1000 hours at 70°C to 6000 hours at 85°C, with a general guarantee of 16000 hours at 30°C.
Polarity and Voltage: Capacitors have polarities and should not be subjected to reverse or over-voltage to avoid reduced life and failures.
Ripple Currents: Due to higher internal resistance, these capacitors may generate heat with ripple currents and are not ideal for ripple current absorption.
Temperature Effects: Lower temperatures extend capacitor life, and usage beyond specified ranges can cause rapid deterioration.
Voltage Drop: Pay attention to voltage drop due to internal resistance, especially in backup mode.
Series Connection: Use bleeder resistors to maintain voltage balance when connecting in series.
Electrolyte and Sleeve: Electrolyte leakage can damage circuits, and the external sleeve is not for electrical insulation.

Mounting:

Heat Stress: Excessive heat during soldering can damage capacitors. Follow specific guidelines for manual and flow soldering to avoid compromising capacitor integrity.
Circuit Design: Avoid placing wiring patterns directly under capacitors to prevent short circuits from potential electrolyte leaks.
Residual Voltage: Capacitors can retain charge, potentially damaging low withstand voltage components.
Circuit Board Cleaning: Follow specified conditions for cleaning after soldering to avoid damage.

Precautions for Use: Avoid environments with water, direct sunlight, high humidity, active gases, or excessive vibrations. Regular maintenance checks are recommended to identify abnormalities.

Storage and Disposal: Store capacitors in a controlled environment (5-35°C, <85% humidity) and dispose of them as industrial waste, following environmental guidelines.

Specifications: Detailed specifications for different series (e.g., HZ, HW) are provided, including temperature ranges, voltage, capacitance, and recommended applications.

Specifications:

HZ Series: Capacitance ranges from 22F to 70F with a maximum operating voltage of 2.3 V.DC. The category temperature range is -25°C to +70°C. Internal resistance is specified to be less than 0.1Ω at 1 kHz.
HL Series: Capacitance ranges from 2.5F to 7.5F with a maximum operating voltage of 2.7 V.DC (2.5 V.DC at 85°C). The category temperature range is -40°C to +70°C (+85°C). Internal resistance is specified to be less than 0.07Ω at 1 kHz.

Endurance and Shelf Life:

For the HZ series, after 1000 hours at 2.3 V.DC and +70°C, capacitance change is within ±30% of the initial value, and internal resistance is less than twice the initial specified value.
For the HL series, endurance is tested at 2000 hours at 2.7 V.DC and +70°C, and 1000 hours at 2.5 V.DC and +85°C, with capacitance change within ±40% of the initial value and internal resistance less than four times the initial specified value.

Recommended Applications: These capacitors are suitable for backup power supply in E-meters, SSD storage, motor driver assistance, and emergency systems like drive recorders and door lock release devices.

Design Considerations: The document advises against using reflow soldering and recommends designing equipment with consideration for IR drop. A space of 2 mm or more should be left above the product to avoid interference with the pressure valve.

Warnings and Cautions:

The components are designed for general-purpose electronic devices. For high-safety applications, such as medical or aerospace equipment, a protective circuit or redundancy arrangement is recommended.
Technical information is provided as examples and does not constitute a warranty or grant any intellectual property rights.
Export of these products may require an export license under Japanese law.

1.1 Product Life The life of an electric double layer capacitor is limited. Its capacitance will decrease and its internal resistance will increase over time. The life of a capacitor greatly depends on the ambient temperature, humidity, applied voltage and discharging currents. Capacitor life can be extended when these parameters are set well below the ratings. The guaranteed durability of electric double-layer capacitors is between 1000 hours at 70 °C and 6000 hours at 85 °C. depending on product series. Generally, it is 1000 hours at 70 °C. The life of the capacitor is guaranteed to be 16000...
