Electrolytic Capacitor EB764413075 Backup Supercapacitor THT

Electrolytic Capacitor EB764413075 Backup Supercapacitor THT is a through-hole mounted energy storage component designed for circuits that require stable capacitance and reliable short-term power backup. The component provides electrolytic supercapacitor performance in a THT package suitable for PCB mounting in industrial modules, consumer electronics, and specialised equipment. Typical roles include keeping real-time clocks running, retaining volatile memory during power loss, and supplying auxiliary power for controlled shutdown sequences.

Advantages

This THT backup supercapacitor offers consistent charge/discharge cycling and stable capacitance over its rated lifecycle, enabling dependable short-term energy delivery. Its through-hole form factor facilitates secure mechanical fixation on printed circuit boards and compatibility with standard wave or manual soldering processes. The electrolytic construction provides a compact energy density for applications that require burst power or memory retention without large battery systems.

Suitable for

• Real-time clock (RTC) backup on motherboards and embedded systems
• Volatile memory retention during brief power outages
• Auxiliary hold-up power for orderly shutdown of microcontrollers and peripherals
• Industrial control modules and measurement equipment requiring short-term energy buffering
• Prototyping and repair of legacy boards that use through-hole capacitors

Key specifications

• Mounting type: through-hole (THT) suitable for PCB insertion and soldering
• Capacitor type: electrolytic supercapacitor designed for backup and short-term power
• Intended use: energy storage for RTC, memory retention, and auxiliary power
• Form factor: cylindrical can or prismatic body optimized for mechanical stability in THT mounts
• Charge/discharge behavior: designed for frequent cycles with controlled leakage characteristics

How to use

Install the EB764413075 backup supercapacitor into the PCB through the designated THT holes, observing polarity markings and recommended spacing from heat sources. Solder using standard wave or hand-soldering techniques suitable for electrolytic components, ensuring correct thermal profiles to avoid damaging the capacitor. Connect the capacitor across the power rail or backup domain as specified in the circuit design so it can supply energy during brief power interruptions and accept charging current within the designed circuit constraints.

Usage recommendations

Place the component away from high-temperature components and provide adequate clearance for ventilation. Observe polarity and recommended soldering temperatures. Verify that the circuit limits inrush current and charging voltage to values compatible with electrolytic supercapacitors. For long-term reliability, design charging and balancing circuits if multiple capacitors are used in series and provide service intervals to inspect for physical degradation in harsh environments.
