Whether it's manual soldering with robotic support, wave and selective soldering or laser soldering – in all assembly tasks, we are able to use any technique required without a problem. Depending on the component, different soldering technologies offer different advantaged. We will adjust the process individually to your project.

Any device is only as reliable as the sum of its components. With more than fifteen years of experience in manufacturing tuned and detuned filter reactors for power factor correction, we are now offering our range of line reactors for application in power electronics. Same as with our capacitors, we focus on minimized power losses and maximum durability of the reactor – optimized for your application. Made of high-class transformer sheets and copper wire or aluminium band. Vacuum-impregnated with environmentally friendly, low-styrole resin for long operating life, high voltage strength and low noise levels. Standard terminals: copper terminal lugs, optional with screw-terminal blocks or cables. Integrated reversible thermal switch for monitoring of the reactor and control of external disconnection in case of overheating. Our standard range covers 400V 50Hz up to 300A per phase. Other values are available on request.

The special kind of films and coating patterns used in our oil-filled E63-capacitors give them a high specific ratio of capacitance to volume and makes them extremely overvoltage proof. Very good self-healing characteristics and the integrated overpressure protection (" BAM ") ensure safe operation and controlled disconnection in the event of overload or failure at the end of operating life. Hence the E63s are interesting particularly for applications with high AC ripple currents, e.g. as smoothing or supporting capacitors in buffer storage circuits, in sensitive environment with high safety requirements. Note that the presence of an overpressure mechanism adds substantially to the self-inductance of the capacitor, and limits the surge current rating. If self-inductance and surge current are important issues, then our E50 or E53 ranges may be considered as a more adequate option.

It works - even in your smaller DC links! A few years ago, our PK16TM pioneered the large-scale shift from batteries of electrolytic DC link capacitors to energy-efficient and highly reliable film capacitors which has become so common nowadays. The E61 range makes the benefits of this substitution available for DC links with smaller powers now. With their pin terminals, these capacitors can be integrated directly into your printed circuit board. The capacitors of the E61 series are optimized for high rms and surge currents. Along with their high specific ratio of capacitance to volume, they offer long-term stability and storability, as well as excellent self-healing without loss of capacitance. It is our advanced know-how in special capacitor film coating, combined with many decades of practical experience in designing and manufacturing capacitors, which have allowed us to develop this range with its numerous advantages over traditional electrolytic capacitors:

In power electronics in general, and especially in low inductance buffer circuits with higher voltages as well as in discharge circuits, the call for capacitors with low inductance tends to pose problems: traditional high voltage capacitors are filled with oil, and the generous bushings required for clearance and 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 self-healing technology, using the opportunities of special metallizing patterns. Despite the high voltage rating, our E51 range is manufactured in dry technology and without expensive bushings. Inside the can made of self-extinguishing plastic, the capacitor element is enclosed in solid resin (PUR). Connection is made through robust flat terminals with internal thread.

Our capacitors of the E12 and E33 series are universally-suited for lighting and motor applications as well as power factor correction and power electronics. Their winding element of self-healing polypropylene film is immersed in eco-friendly vegetable oil and designed for highest requirements regarding operational life and functional safety even at high operating temperatures and other extreme conditions such as high humidity. Connection is made through tab connectors. The hermetical aluminium can is provided with an integrated overpressure safety mechanism (break-action mechanism, " BAM ") that disconnects the capacitor irreversibly from the supply in the event of a failure. The E12/E33 ranges comply with the "Type B" classification under lighting standard IEC/EN61048 as well as with "Class P2" under motor capacitor standard IEC/EN 60252-1. Please mind our safety remarks on the use of lighting capacitors in critical environment.
