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
Parts are readily available in sample and production volume quantities and can be supplied in standard tape and reel format.
