What are the key features of EECHW0D105?
- 1 F capacitance at 2.3 V rated voltage in a compact 8 mm diameter radial leaded cylindrical package
- Electric double-layer (EDLC) technology using activated carbon for fast charge/discharge cycles and long cycle life exceeding 100,000 cycles
- Through-hole radial mounting with ±20%/+40% tolerance supports easy PCB integration in backup power and energy buffering circuits
What is EECHW0D105 used for?
The EECHW0D105 is designed for energy storage and backup power applications in IoT devices, microcontroller real-time clock (RTC) backup circuits, and portable consumer electronics requiring a compact 1 F supercapacitor. Its 2.3 V rating and 8 mm cylindrical radial package are well-suited for coin-cell replacement circuits and short-duration power hold-up circuits during main power interruptions. The activated carbon EDLC technology enables rapid charge and discharge cycles without the cycle-life limitations of conventional electrolytic capacitors.

Frequently Asked Questions
How long can the EECHW0D105 maintain 3.3 V supply to a microcontroller RTC during a power outage?
The EECHW0D105 stores 1 F at 2.3 V rated voltage, delivering approximately 2.645 mJ of usable energy when discharged from 2.3 V to 1.0 V. For a microcontroller RTC drawing 1 µA at 3.3 V, a paired boost converter with high efficiency can sustain the circuit for several hours, though at higher load currents of 1 mA the hold-up time reduces to tens of seconds, making this supercapacitor ideal for short-duration backup scenarios.
How does the EECHW0D105's cycle life compare to an electrolytic capacitor used in similar energy buffer roles?
The EECHW0D105 EDLC supports over 100,000 charge and discharge cycles due to its non-Faradaic activated carbon double-layer mechanism, which does not degrade the electrode material with each cycle. In contrast, standard aluminum electrolytic capacitors in energy buffer roles typically endure fewer than 10,000 cycles before capacitance drops below 80% of rated value, making the 1 F supercapacitor superior for applications with frequent power cycling.
What PCB footprint and lead spacing does the EECHW0D105 require for through-hole assembly?
The EECHW0D105 uses a radial leaded through-hole package with an 8 mm body diameter and standard 2.5 mm lead pitch. The cylindrical 8 mm body height requires a PCB clearance zone of at least 9 mm above the board surface. Designers should drill 0.8 mm to 1.0 mm plated through-holes at 2.5 mm center-to-center spacing to accommodate the radial leads without mechanical stress on the capacitor body.
