Safety capacitor range offers higher capacitance values
May 08, 2013 // Paul Buckley
Syfer has added to the company's UL and TÜV approved range of SMD 250 Vac safety capacitors. To give engineers more scope in their designs, the upper capacitance value has been extended to 33 nF.
The new higher capacitance devices expand Syfer’s B16 (TÜV/UL approved) and B17 (TÜV approved) safety certified capacitor ranges. Values in the 2220 package size are now available up to an impressive 22 nF for the B16 X2 rating, and to 5.6 nF for the B17 Y2/X1 rating. If the ProtectiCap option is specified, the upper value for B16 devices increases to 33 nF.
The ranges are approved for direct connection across AC mains voltages up to 250 Vac. The devices are used for transient and surge protection in networked and mains-based electronic equipment, across a range of industry sectors. The devices provide valuable safeguards against lightning strikes and other transient events that represent a threat to electronic equipment. Typical applications include data switches/modems and AC-DC power supplies.
Syfer’s FlexiCap termination is an option available for all sizes in this range up to and including the 2220 format devices. Syfer is one of few manufacturers worldwide offering MLCCs with flexible terminations with certification to IEC, EN and UL safety standards.
For engineers designing equipment to meet IEC 60950, these parts are ideal as they have approvals to IEC 60384-14:2005, UL60384-14:2010 as well as UL 60950-1.
UL and/or TÜV approvals are often a critical factor in component choice for manufacturers supplying to top tier OEMs, service providers and systems builders. Gaining approvals for these range extensions is an essential part of Syfer’s new product introduction programme, designed to meet customer demand for increased capacitance ranges in smaller packages.
Parts are readily available in sample and production volume quantities and can be supplied in standard tape and reel format.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
