Introduction
ELECTRONICON presents the E61 series of high-density film capacitors as a compact and efficient alternative to traditional electrolytic capacitors in DC link applications. These capacitors are particularly suited for use in lean buffer circuits within frequency-controlled AC drives, which are essential for modern automation systems.

Specifications and Advantages
The E61 capacitors offer several advantages over electrolytic capacitors, including reduced component count, weight, and cost, as well as enhanced reliability and longer operating life. For example, in a 5kW drive application, a single E61 capacitor can replace multiple electrolytic capacitors, resulting in significant space and weight savings.

Technical Comparison
Compared to electrolytic capacitors, the E61 series provides lower equivalent series resistance (ESR) and higher current handling capabilities. This results in reduced power losses and improved efficiency. The capacitors are designed for high RMS and surge currents, with pin terminals for easy integration into printed circuit boards.

Design and Safety Considerations
The E61 capacitors are housed in flame-retardant plastic filled with solid resin, offering excellent self-healing properties and long-term stability. However, they lack an internal fail-safe device, necessitating careful placement in non-critical environments or the integration of additional safety measures.

Cost and Performance Benefits
Using E61 capacitors can lead to a cost reduction factor of five compared to electrolytic capacitors, not accounting for indirect savings from improved reliability and reduced power losses.

Technical Data
The capacitors comply with IEC 61071 standards and are available in various voltage ratings and capacitance values. They operate within a temperature range of -40°C to +85°C and have a FIT rate of 50, indicating high reliability.

Company Background
ELECTRONICON Kondensatoren GmbH, based in Gera, Germany, has over 70 years of experience in capacitor manufacturing. The company is committed to innovation and quality, with a focus on MKPg-technology and environmentally sound manufacturing practices.

Conclusion
The E61 series film capacitors offer a reliable, cost-effective, and space-saving solution for DC link applications in modern electronic drives, making them a preferred choice for manufacturers seeking to enhance performance and reduce costs.
