Supercapacitor energy buffer for smart meters and IoT devices - jb Capacitors
Supercapacitors as energy buffers in smart meter / IIoT rails.

Super capacitors reduce voltage dips and prevent resets under transient loads. Pair batteries with low-ESR jb® JGM (5.5/7.5 V) or low-leakage JGY (5/7.5 V) to extend battery life and keep systems stable across wide temperatures. [1][2]

How Super Capacitors Bridge the Power Gap

Deliver peak current in milliseconds, recharge in seconds, and stabilize the DC bus to mitigate ripple. [1][4]

JGM / JGY at a glance
SeriesTypeVoltageKey FeatureTypical Application
JGM Low ESR combined type 5.5 V / 7.5 V Low impedance; stable discharge for high-current pulses Smart meters, RF modules, IIoT gateways
JGY Low leakage combined type 5.0 V / 7.5 V Low self-discharge; long cycle life Embedded controllers, sensor nodes, data retention

Performance & Reliability

Low-ESR combined types keep C within ±30% and ESR within 4× even after 1M cycles at 25 °C; jb® JGY 7.5 V shows consistent discharge for buffer roles. [6]

Both series operate from −40 °C to +70 °C with predictable leakage and ESR drift for outdoor metering and industrial control. [2][5]
