Mersen Delivers Spare Parts for Railway Technology
Mersen highlights products of the S series that are still required on a regular basis as important spare parts especially in railway technology.
Mersen is one of the few remaining manufacturers that can fill orders for aluminum electrolytic capacitors with threaded connections. The products of the S series are still required on a regular basis as important spare parts, especially in railway technology.

Conrad Zuse used them in his first commercial computer, without them tube radios would not have made any sound, and even today they ensure the proper functioning of railway switching and connecting components in older relay signal boxes: Capacitors of the FTCAP S series are truly an “oldie but goldie”. The special feature of these capacitors is the use of threads, which makes it possible to screw them into a suitable hole in a mounting plate. Although passive electrical components are now generally soldered to the printed circuit board in an automated process, this threaded connection technology still proves its worth today in large aluminum electrolytic capacitors for high current loads.
The Mersen portfolio includes three different models of the type S capacitors: In addition to the standard version with single capacitance (S series), the company also offers capacitor models with double and triple capacitance (SZ and SD series), as well as high-temperature variants up to 105 °C (SH series). On request, the legacy models can also be adapted to modern-day requirements for high capacitance and electric strength. Incidentally: Due to a donation of capacitors by Mersen, a type Z-22 Zuse computer built in 1959 still operates flawlessly at the Suderburg University of Applied Sciences.
