Technical data, safety guidelines, mounting instructions and ordering codes for EPCOS aluminum electrolytic capacitors.
This document provides comprehensive technical information for EPCOS aluminum electrolytic capacitors, including construction details, electrical parameters, climatic limits, flammability, mechanical stress resistance, and quality and environmental management. It also contains important safety notes, cautions, and handling recommendations.
The publication includes selection charts for screw‑terminal and snap‑in capacitor families, detailed ordering‑code composition, and extensive tables of specifications such as rated voltage, capacitance, ESR, and permissible ripple current. It is intended for designers, manufacturers, and end‑users who need precise data for product selection and reliable integration. This manual is written in Chinese.
| Rated voltage (VR) | varies by series (e.g., 25 V, 35 V, 50 V) |
|---|---|
| Capacitance | range from 0.1 µF to 1500 µF |
| Typical ESR | e.g., 0.05 mΩ at 120 Hz, 20 °C |
| Maximum AC ripple current (I AC,max) | specified per case size, e.g., 0.5 A at 120 Hz, 40 °C |
It is recommended to operate the capacitor at 70–80 % of its rated voltage to optimize service life.
Store them at normal temperature in a non‑acidic, non‑alkali environment with normal humidity; avoid direct sunlight and high temperatures.
Capacitors with a case diameter ≥ 8 mm are equipped with a safety vent that must have sufficient clearance around it.
Use a soldering iron temperature of 350 °C for about 3 seconds, ensuring the tip does not touch the capacitor body.
