Why Do IoT Devices Fail Prematurely?
Most IoT sensors and wireless modules die not because the electronics fail, but because their power source gives out. Small batteries can't handle burst transmissions. EDLCs don't store enough energy. What you need is something between a battery and a capacitor—something that delivers high pulse current, lasts hundreds of thousands of cycles, and doesn't leak energy when idle.
The LIHC1016-3R8-50F Is That Solution
This 3.8V 50F lithium-ion hybrid capacitor stores just enough energy for backup and burst applications, discharges at 4.0A when you need it, and recharges at 400mA without degrading. It runs for 250,000 cycles. It works from -40°C to 65°C. It holds its charge with less than 4μA leakage. And it fits in a 10x16mm cylinder weighing 3 grams.
When to Use It
Smart meters that wake up once an hour to transmit data. GPS trackers that send location pings. Wireless sensors that log temperature and humidity. Backup power for real-time clocks and memory retention. Peak power support for industrial controllers. Any application that needs a quick burst of energy, repeated thousands of times, over years of service.
Technical Data
50F capacitance measured between 3.8V and 2.5V. DCR ≤400mΩ. ACR ≤175mΩ. 200mA continuous. 4.0A pulse. 400mA max charge. 4μA leakage. -40°C to 65°C operating. 10°C to 40°C storage. Shipped at 3.3V to 3.8V. Passes overcharge, short circuit, thermal, and mechanical abuse tests with no fire or explosion.
Bottom Line
If your device needs long life, wide temperature range, and reliable pulse power, the LIHC1016-3R8-50F is the component you're looking for. It outlasts batteries. It outperforms EDLCs. It's maintenance-free. And it's ready to ship.
