GD Rectifiers collaborate with API to launch an ultra low temperature electrolytic capacitor

GD Rectifiers are proud to announce the launch of the new ultra low temperature electrolytic capacitor 


GD Rectifiers is a global manufacturer and distributor of products, services and solutions to commercial and industrial users of power electronic components. GD Rectifiers are the UK’s leading distributor for API capacitors; a UK based specialist manufacturer of custom and high specification capacitors.


GD Rectifiers announced the launch of the new and innovative ultra low temperature capacitor last month; an industry development which will cater to many industrial processes operating in extreme environments.


Paul Bentley, managing director of GD Rectifiers said of the development: “The inspiration behind this concept was the petrochemical industry – it operates throughout the world from the deserts of the Middle East right the way to the Arctic. It’s important that safety equipment operates reliably at these extremes as very low temperatures present a particular problem for electrolytic capacitors that rely on a liquid electrolyte to function. We wanted to take further action to increase the existing safety measures in place so our team of experts designed the ultra low temperature electrolytic capacitor. We designed the prototype in June this year, started production in August and rolled out our first order earlier this month.”


Until now, electrolytic capacitors used for industrial specifications have had an operation temperature from between -25°C to +85°C. This has led to the need of improvements in capacitors required in extreme operational and high reliability environments.


“A wider temperature range paired with high reliability has necessitated the extension of the operational range from -55°C to +105°C. Our new ultra low temperature capacitor will typically be used in Aerospace, Compressed Gas Handling, Environment Testing, Hazardous Environment, Petrochemical, Refrigeration Systems, Research and other industrial applications,” Paul Bentley mentioned.


Electrolytic capacitors can exhibit large changes in capacitance at low or high temperatures. Traditionally, at low temperatures capacitors lose a major portion of their capacitance – until now.


GD Rectifiers now stock both low temperature electrolytic capacitors, ranging from -40°C to +105°C and ultra low temperature electrolytic capacitors which range from -55°C to +105°C.


The new ultra low temperature electrolytic capacitor maintains the level of capacitance required and has created a more diverse range of electrolytic capacitors for companies and engineers to choose from.
