Exxelia SIC SAFCO celebrates its 100th anniversary !

Founded in 1921, SIC SAFCO, the historical brand of our electrolytic capacitors, is celebrating its 100th anniversary this year!


Founded in 1921, SIC SAFCO, the historical brand of our electrolytic capacitors, is celebrating its 100th anniversary this year!

We have come a long way since the creation of the Société Industrielle des Condensateurs (SIC)!

In 1930, Louis Ségal, the founder of SIC, set up his company in Colombes, in the Hauts de Seine region of France, and presented a patent for the manufacture of a three-phase capacitor with insulated wound sheets.  

In 1935, the French company for the manufacture of electrical capacitors (SAFCO) was born. SAFCO merged with SIC in 1954 to form the SIC SAFCO brand. 


This is the beginning of a great adventure for SIC SAFCO which will launch several ranges of capacitors such as : 


- The SNAPSIC range of aluminium electrolytic snap-in capacitors 
- The CUBISIC range of aluminium electrolytic radial capacitors 
- The FELSIC range of aluminium electrolytic capacitors with screw terminal

Some changes for SIC SAFCO which inaugurates its new site in Saint Nazaire in 2011 then change of name in 2015 for Exxelia SIC SAFCO.

In 2018, with the merger of Exxelia's French entities, Exxelia SIC SAFCO becomes Exxelia SAS.

Let's finish with the last news of the brand: the release in 2021 of the CUBISIC SLP range of radial electrolytic aluminium capacitors.

Felsic HV, long lifetime and high voltage screw terminal aluminum electrolytic capacitor The Felsic HV family of aluminum electrolytic screw terminal capacitors provides great performances in energy density and ultra-long lifetime. For instance, 6 800µF @450V fit into a  volume of Ø77 x 220mm  and can withstand 200,000h between 0 to 70° under 37Amps, which makes them the perfect choice for use in rolling stock traction systems or the CVS. The family also has one of the lowest ESR for aluminum capacitors with less than 10m0hms in most cases. Products are available for voltages from 160 to 450 Vdc, and offer capacitance values from 1500μF up to 47 000μF offering the best compromise between reliability and compacity. Snapsic HV, high voltage snap aluminum electrolytic capacitor Because it covers voltages from 16 to 500Vdc and temperatures up to +105°C, and because it is customizable, the Snapsic HV series is very versatile and can cover all needs of energy storage in medium voltage both in rolling stock equipment or signaling systems. Thanks to its high ripple current, it is often used in SMPS and HVAC rolling stocks units with a typical variation of 470µF @450V in Ø35 x 50mm, as well as in various signaling control units, where a smaller package can be used with for example 1 000µF @250V in Ø35 x 40mm.   Prorelsic, the long lifetime axial aluminum electrolytic capacitors for signaling equipment Exxelia’s range of aluminum electrolytic solutions would not be complete without the axial leaded Prorelsic series. These capacitors show high ripple current and extra-long life-time with 20 000h @105°C. The most common sizes are Ø8.5 x 19mm, Ø10 x 19mm and Ø12 x 30mm, with typical values of 47µF @40V, 100µF @25V and 47µF @100V respectively. Prorelsic capacitors are perfectly suited for smoothing, coupling/decoupling and energy storage functions in railway signaling equipment.
