The UPC1520 Battery Capacitor is positioned as a compact, general-purpose pulse-support solution for battery-powered electronics that combine long standby periods with brief high-current events.
With an approximate size of 15 mm in diameter and 20 mm in height, it offers more energy and power-support capability than ultra-miniature capacitor formats while remaining small enough for compact meters, wireless security devices, tracking equipment, and embedded IoT systems.
A Practical Partner for Li-SOCl₂ Batteries
Many Li-SOCl₂-powered devices are optimized for extremely low average current over several years. The challenge appears when a communication module, actuator, or radio circuit suddenly requires substantially more current for a short period.
UPC1520 can be paired with cells such as ER14250 or ER14505 to support these transient loads.
In this hybrid architecture, the primary battery provides long-term energy while the battery capacitor supplies additional power during events such as:
- NB-IoT or LoRa transmission
- RF communication
- device wake-up
- smart lock actuation
- status reporting
- emergency data transmission
This can reduce the instantaneous load placed directly on the primary cell and provide greater design flexibility for wireless devices.
Well Matched to Compact Wireless Systems
UPC1520 is particularly useful in products where pulse demand is meaningful but enclosure size still needs to remain compact.
Its 15 × 20 mm form factor makes it suitable for devices that have more internal space than ultra-miniature trackers or tags, yet cannot accommodate a large capacitor or substantially larger battery system.
This balance makes UPC1520 a practical option for mainstream metering, IoT, security, and telemetry applications.
Typical Hybrid Applications
Smart Meters
Suitable for smart water meters, smart gas meters, and other utility endpoints using NB-IoT, LoRa, or similar wireless communication. The capacitor can support transmission peaks while the ER cell supplies long-term background energy.
ETC & OBU Devices
Applicable to electronic toll collection tags and on-board units that remain in low-power mode for extended periods but need rapid wake-up and short bursts of RF communication when passing through a tolling point.
Smart Home Security
Can be combined with primary lithium cells in wireless door/window sensors, smart locks, alarm devices, and other security products that alternate between standby and short active events.
Asset Tracking
A practical choice for GPS, Bluetooth, RF, and other tracking devices where location acquisition and wireless transmission periodically increase power demand.
Standalone Energy Support Applications
UPC1520 can also be used independently in selected systems where short-duration energy storage is more important than maintaining a long continuous discharge.
Industrial Vibration Sensors
Can work with piezoelectric or other energy-harvesting sources in condition-monitoring sensors for motors, pumps, and rotating equipment. Harvested energy can be accumulated and released during measurement, processing, or wireless reporting.
Short-Term Backup Power
The capacitor may provide temporary energy after the main power supply is interrupted, allowing selected electronics to save data, complete a shutdown sequence, or transmit a power-loss notification.
Actual backup duration depends on the stored energy, load current, voltage window, and complete circuit design.
Designed for Long-Term Device Integration
Battery capacitors used in unattended electronics must remain stable over long deployment periods rather than simply delivering one high-power event.
UPC1520 uses a compact cylindrical structure with laser-sealed construction intended to support sealing integrity and long-term reliability in industrial and outdoor electronic applications.
Its combination of small size and pulse-support capability makes it particularly useful where designers need to add transient power without significantly increasing the overall size of the battery system.
