EECF5R5U155 Visão geral
Background: An EDLC (Electric Double Layer Capacitor), also called a supercapacitor or ultracapacitor, is an electrochemical energy-storage device that stores charge at the interface between a high-surface-area activated-carbon electrode and a liquid or organic electrolyte. Within the energy-storage taxonomy, EDLCs sit between conventional capacitors (very fast, very low capacity) and lithium-ion batteries (slow, very high capacity), trading energy-per-mass for charge/discharge speed and cycle life. They belong to the broader passive-components category of capacitors, and within Panasonic's lineup they are part of the "NF" stacked-coin-type Gold Capacitor family.
Key differentiating features include the 5.5 V working rating (which suits one-cell lithium primary or alkaline backup rails), the radial pin/male through-hole termination (which permits hand-soldering or wave-soldering), and the 1000-hour 70°C load life (which exceeds many competing coin-type EDLCs at the same capacity). The ESR of 30 ohm at 1 kHz, while high by aluminum-electrolytic standards, is typical for coin-cell EDLCs of this capacitance class.
Typical applications include memory backup for video recorders, audio equipment, cameras, telephones, printers, data terminals, rice cookers, and intelligent remote controllers. Each of these systems needs seconds-to-days of hold-up time to preserve user settings, RTC content, or last-state memory during mains loss — a perfect fit for a 1.5 F / 5.5 V EDLC.
When designing with this device, note that EDLCs MUST NEVER be charged without current limiting or a series resistor; inrush into a fully discharged 1.5 F cell can exceed several amps and damage the dielectric interface. Always observe the 5.5 V maximum working voltage, and apply a reverse-blocking diode when paralleling with a primary cell to prevent charging the EDLC above its rated voltage.

Aplicações típicas
EECF5R5U155 é adequado para 7 aplicaçãos: Video Recorder Memory Backup, Audio Equipment Memory Backup, Camera and Camcorder Settings Backup, Cordless Telephone Memory Backup, Printer and Data Terminal Memory Backup, Rice Cooker and Smart Home Appliance Backup, Industrial RTC and PLC Memory Backup.
Video Recorder Memory Backup
The Panasonic EECF5R5U155 is a classic fit for VCR and DVR memory backup where it preserves channel presets, clock settings, and last-viewed state across mains interruptions. With 1.5 F at 5.5 V, the cell holds roughly 22.7 J of usable energy, which translates to several hours of hold-up for a typical 32-Kbit SRAM plus RTC load drawing under 100 uA. The 5 mm pin pitch and radial Through-Hole coin package mount directly on the main PCB next to the backup diode and current-limit resistor. Place a 1N4148WS blocking diode and 47 ohm in-rush resistor in series; the EDLC cannot tolerate reverse voltage above ~0.3 V.
Recomendado
Audio Equipment Memory Backup
Audio equipment such as stereo receivers, CD players, and cassette decks uses the EECF5R5U155 to retain station presets, volume curves, and last-track memory through brief blackouts or unplugging. The 30 ohm ESR is irrelevant for these uA-level hold-up loads, and the 5.5 V ceiling drops directly onto a 5 V regulator rail after a series blocking diode. The 1.5 F cell outlasts any electrolytic or tantalum in this role by orders of magnitude and survives hundreds of thousands of charge cycles versus single-use lithium coin cells.
Recomendado
Camera and Camcorder Settings Backup
Digital cameras and camcorders draw on the EECF5R5U155 to back up exposure settings, date/time, and user preferences when the main battery is removed for replacement. The radial package drops onto existing NF-series footprints in many legacy designs with 5 mm lead pin compatible. Pair the cell with a low-leakage supervisor such as the TPS3823 to give the MCU a clean reset during the battery-change window. Operating temperature range is constrained to the -25°C to +70°C window, which covers all consumer-camera use cases.
Recomendado
Cordless Telephone Memory Backup
Cordless and corded telephone handsets employ the EECF5R5U155 to back up the dialed-number memory, address book, and CID buffer during power loss. The 1.5 F / 5.5 V rating is well-matched to the 3.6 V NiMH battery stack that powers the cordless base, with a series diode dropping into the hold-up rail. The 30 ohm ESR limits pulse current, but telephone backup loads are pure uA-level, so this is irrelevant. The 1000-hour 70°C load life is more than sufficient for consumer telephone duty.
Recomendado
Printer and Data Terminal Memory Backup
Thermal printers, receipt printers, and POS data terminals use the EECF5R5U155 to hold job queue state, last-printed flags, and configuration during power cycles. The 5.5 V rating drops onto a 5 V logic rail cleanly after a Schottky-series-blocking diode, and the radial Through-Hole coin package drops onto existing PCB footprints without modification. Verify your worst-case backup load is below ~150 mA peak; the 30 ohm ESR caps peak discharge current at roughly 180 mA at full 5 V. For heavier loads, parallel two cells or step up to a 1 F / 5.5 V higher-capacitance cell.
Recomendado
Rice Cooker and Smart Home Appliance Backup
Microwave ovens, rice cookers, and intelligent remote controllers hold the keystone pattern of low-power kitchen-appliance memory backup on the EECF5R5U155. The 5.5 V ceiling matches single-cell alkaline stacks, the wide operating-temperature window (70°C upper bound) covers inside-of-enclosure temperature zones, and the radial Through-Hole package drops onto chip-pin layouts at the keystone-test row of any PCB layout house. The cell survives daily charge cycles for years, making it ideal for always-backup appliances.
Recomendado
Industrial RTC and PLC Memory Backup
Industrial PLCs, intelligent remote controllers, and SCADA RTUs deploy the EECF5R5U155 to preserve setpoints, calibration constants, and event logs through brownouts and battery swaps. The radial package is rated for -25°C to +70°C operation, covering most industrial-cabinet environments. For outdoor or sub-zero applications, an industrial-rated LTC/SMC supercapacitor is required. The 1.5 F cell at 5.5 V pulls the keystone over industrial drivetrain parameters in PLC backup applications, and the through-hole radial coin drops directly onto keystone-test row PCB layouts.

Notas de projeto
Always charge EECF5R5U155 through a current-limiting resistor (10–100 ohm recommended) or constant-current source. A fully discharged 1.5 F cell has effectively zero internal resistance, and direct connection to a 5 V rail will drive tens of amps of inrush through the cell, damaging the double-layer interface and shortening life. A 47 ohm series resistor limits inrush to about 100 mA at 5 V, which is well within the cell's safe operating envelope and adds negligible steady-state loss during the backup discharge phase.
EDLCs are polarized devices with a maximum reverse voltage of only about 0.3 V. Always include a series blocking diode (1N4148WS or Schottky B240A for lower loss) on the positive terminal when paralleling with a primary cell, lithium coin cell, or any source capable of reverse-charging the EDLC. Reverse voltage above the limit causes gas generation inside the cell, permanent capacity loss, and potential venting. Never use an EDLC as a direct substitute for an unpolarized aluminum electrolytic in a coupling or filter role.
Estimated: At 25°C ambient and continuous 5.5 V operation, the EECF5R5U155 self-discharge losses are negligible and the cell stays near ambient. Above 60°C ambient, lifetime drops sharply; the 1000-hour load life spec at 70°C is the published derating point. For applications above 60°C continuous, derate by 50% per 10°C or move to a higher-temperature part. Storage above 70°C permanently reduces capacitance; long-term storage should be at 25°C or below, ideally shorted to maintain the cell's voltage profile.
The radial through-hole coin package requires a 5 mm lead pitch footprint. Place the cell away from heat sources (linear regulators, transformers, power resistors) and ensure the polarity marking is visible during manual assembly. For wave-soldering, use a thermal shield to prevent the coin can from exceeding 70°C during the soldering operation; many production lines use a manual solder touch-up for the second lead to avoid overheating the cell. Hand-soldering is straightforward with a 1.5 mm chisel tip and 350°C iron.
Informações de conformidade
RoHS compliance flag was not present in the verified web data; AEC-Q100 is not applicable to passive EDLC components in consumer-grade Panasonic NF series. All compliance values set conservatively to 'unknown' rather than guessed.
