Product Overview:
The LIHC1840-3R8-750F is a high-capacity, 3.8V 750F Lithium-Ion Hybrid Capacitor (LIHC) engineered for demanding applications that require both rapid power delivery and deep energy storage. By merging an activated carbon capacitive cathode with a lithium-ion intercalation graphite anode, this advanced hybrid device bridges the gap between traditional EDLC supercapacitors and standard batteries.
Utilizing both non-faradaic (capacitive) and faradaic (battery-like) storage mechanisms, it delivers an exceptional balance of high energy density, 30A pulse discharge capabilities, and a maintenance-free lifespan of over 250,000 cycles.
Designed to perform reliably in extreme environments, it features a wide operating temperature range (-40°C to 70°C) and ultra-low self-discharge, making it the ultimate power management solution for next-generation industrial, IoT, and backup systems.
Key Features and Advantages
Optimized Dual-Mechanism Architecture: Combines high power density with significantly higher energy density than traditional EDLCs.
Superior Power Performance: Supports a continuous discharge current of 3.0A and pulse currents up to 30.0A (<1s).
Extended Life Cycle: Built for longevity with a typical lifespan of ≥250,000 cycles, boasting high capacitance retention (≥70%) even after extensive cycling and high-temperature floating tests.
Extreme Temperature Resilience: Fully operational from -40°C up to 70°C, maintaining ≥70% of its initial capacity at low temperatures (-20°C).
Low Self-Discharge & Maintenance-Free: Features an ultra-low leakage current (≤12.0μA after 72 hours) and excellent high-temperature/high-humidity storage stability.
Applications
IoT & Smart Utility Meters: Ideal for gas, water, and electricity smart meters requiring long-term reliability.
Wireless Communication Modules: Provides the necessary peak power support for RF, cellular, and GPS tracking data transmissions.
Backup Power & UPS Systems: Ensures safe, reliable hold-up power for critical electronics during sudden supply interruptions.
Energy Buffering: Smooths out power spikes and assists in pulse-load peak shaving in industrial environments.
