High Performance Supercapacitor (EDLC) DMF Series

Product catalog summary
Overview: This document outlines the specifications and guidelines for Murata's DMF Series supercapacitors, designed for high power density and compact size, ideal for portable devices and efficient energy storage applications.
Features and Benefits: The supercapacitors offer higher output power, high allowable current, low ESR, stable performance at low temperatures, long cycle life, low leakage current, and maintenance-free operation.
Applications: Suitable for peak power assist in LED flashes, smart meters, e-paper, backup applications like POS systems and UPS, energy harvesting, and battery peak load leveling.
Specifications: Rated Voltage: 5.5V; Nominal Capacitance: 470mF to 1000mF; ESR: 40mΩ to 45mΩ; Operating Temperature: -40°C to +70°C; Storage Temperature: -40°C to +85°C.
Design and Handling Cautions: Includes voltage balance control, correct polarity, AC operation considerations, environmental precautions, and guidelines for resin coating and disposal.
Performance and Validation: Details performance validation methods with graphs showing capacitance and ESR changes over temperature and time.
Specifications and Compliance: Energy capacity is under 0.3Wh, exempting certain regulations. Emphasizes adherence to specifications and obtaining approval sheets.
Soldering and Assembly Cautions: Recommends hand soldering with specific conditions and cautions against excessive force during assembly.
Storage Conditions: Store at 30°C and 60% RH for up to one year before opening; post-opening warranty is three months with specific conditions.
Packaging: Minimum shipping quantity is 500 pieces, packaged in trays.
Export Control and Usage Restrictions: Restrictions on use in weapons or military systems; consultation required for high-reliability applications.
Product Specifications and Changes: Specifications may change without notice; verification with Murata is advised.
Intellectual Property and Environmental Compliance: Murata disclaims responsibility for IP disputes; no ozone-depleting substances used in manufacturing.
