The Knowles SYS family offers class Y2/X1 safety capacitors,
including humidity robustness grade III, 5kV impulse and a
1kVdc rating, approved by TÜV and UL for use in machinery
within the scope of IEC 62368. Unmarked components (UYS
suffix) can be offered with a 2500Vdc rating and are designed
to comply with, but are not approved to, EN60384-14.

SYS and UYS components have a creepage <4mm,
and as a result, their safety certifications are only valid
for applications within the scope of IEC 62368.
Ref: EN60384-14, clause 4.8.1.3.
Notes: Blue Background = AEC-Q200.
* For lower capacitance values in this family, the maximum part thickness will be lower than the
value shown. To find out the maximum thickness for a specific part, please use the Part Builder or
Part Search application on the Knowles website to generate the component datasheet.
