Why Smart Meters Use Supercapacitors: Real-Time Clock and Pulse Transmission
How supercapacitors support RTC retention, last-gasp messages, and RF pulse buffering in smart meters — and what to check for 15+ year lifetimes.
Supercapacitor Sizing Guide for IoT Transmission Pulses
Size a supercapacitor to buffer LoRa, NB-IoT and LTE-M bursts: pulse charge, ESR droop, leakage vs sleep current, and recharge time.
EDLC vs Lithium-Ion Capacitors: Performance and Trade-Offs
Compare EDLC supercapacitors with lithium-ion capacitors on voltage window, energy density, self-discharge, low-voltage limits, and handling.
How to Read a Supercapacitor Datasheet: Key Parameters for Engineers
A parameter-by-parameter walkthrough of supercapacitor datasheets: capacitance test methods, AC/DC ESR, leakage, life tests, and temperature curves.
Radial vs Snap-In vs Coin Cell: Choosing the Right Form Factor
Compare supercapacitor form factors — coin cell, radial lead, snap-in and screw terminal — on current, capacitance, mounting, and assembly.
Replacing Batteries with Supercapacitors: Feasibility Checklist
A feasibility checklist to decide whether a supercapacitor can replace a backup battery: energy, runtime, voltage window, leakage, and lifetime.
