Product catalog summary
Introduction
The document introduces the E51, E53, and E55 series of low-inductance film capacitors designed for high voltage applications in power electronics. These capacitors are ideal for low inductance buffer and discharge circuits, addressing challenges of traditional high voltage capacitors.
E51 Series
The E51 capacitors are designed for high voltage and low inductance, featuring self-healing technology and special metallizing patterns to minimize self-inductance, reducing the risk of partial dielectric discharges and failures.
E53/E55 Series
The E53 series is suitable for high RMS and surge currents with low self-inductance, ideal for damping GTO thyristors. The E55 series is optimized for large capacitances at high voltages. Both series have high pulse strength and self-healing characteristics.
Design and Construction
All capacitors are housed in flame-retardant plastic cans filled with solid resin, designed for reliable operation under tough conditions, with robust connections for easy mounting.
Technical Specifications
Specifications include voltage ratings, capacitance, resistance, inductance, thermal resistance, and maximum current ratings. The capacitors comply with IEC 61071 and optionally IEC 61881 standards.
Data Charts
Data charts for the E51 and E53 series list models with specific electrical parameters, dimensions, and order numbers, aiding in selecting the appropriate model based on application requirements.
Specifications
Detailed specifications for low-inductance DC capacitors with voltage ratings from 500V to 5000V DC, available in various configurations with different capacitance values, dimensions, and weight.
Standards and Materials
Capacitors comply with IEC 61071 and optionally IEC 61881 standards, housed in plastic cases filled with solid polyurethane resin, ensuring an environmentally friendly design.
Operating Conditions
Designed to operate within -25°C to +85°C, with a maximum hotspot temperature of 85°C, a failure rate of 50 FIT, and a reference service period of 100,000 hours at 70°C.
Mounting and Cooling Recommendations
Proper cooling is essential to maintain lifespan. An increase in ambient temperature by 7°C can halve the expected life. Forced ventilation is recommended, with a clearance of at least 20mm for ventilation.
Protection Features
Features a self-healing dielectric, ensuring functionality during and after voltage breakdown, designed to be short-circuit and overvoltage-proof within specified limits.
Failure Rate and Reliability
Failure rate influenced by operating temperature and voltage. FIT rates related to rated voltage and a dielectric temperature of 70°C are provided.
Important Safety Remarks
ELECTRONICON disclaims responsibility for damages due to improper application. Capacitors should be used only for their intended purpose to avoid hazardous situations.
Specifications and Recommendations
Emphasizes avoiding operation at the highest permissible voltage and temperature to prevent high failure rates. FIT rates can be improved through technical adjustments.
Warranty Information
A 3-year limited warranty covers defects due to faulty design, materials, or workmanship, excluding defects from improper use or operation beyond rated values.

t5i High voltage, low inductance, long-term safe opration In power electronics in gn驩ral, but particularly in low inductance buffer circuits with higher voltages and in discharge circuits, the call for capacitors with low inductance poses problems. Traditional high voltage capacitors are filled with oil, and the generous bushings required for clearance/creepage as well as internal safety mechanisms add substantially to the self-inductance of the capacitor. Based on decades of proprietary experience in metallizing capacitor films, ELECTRONICON has created a range of high voltage capacitors in...

Failure Rate The failure probability of a component is a statistical value which is described by a log-normal distribution: Ausfallrate Die Ausfallwahrscheinlichkeit eines Bauelements ist eine statistische Grofie, die mit Hilfe einer Normalverteilung beschrieben wird. Es gilt: N = No x e~Xt N = number of functional components after period t Anzahl der nach der Zeit t intakten Bauelemente No = total number of components at time t = 0 Gesamtzahl der Bauelemente zum Zeitpunkt t = 0 X = failure rate Ausfallrate X is the failure rate, which alternatively is also stated as the so-called FIT-rate (FIT...
