PME271 Datasheet, PDF (1/4 Pages) Kemet Corporation – EMI suppressor, classes X1, X2 and Y2, metallized paper

PME271
• EMI suppressor, classes X1, X2 and Y2, metallized paper
• The highest possible safety regarding
active and passive flammability.
• Self-extinguishing UL 94V-0 encapsulation
material.
• Excellent self-healing properties. Ensures
long life even when subjected to
frequent overvoltages.
• Good resistance to ionisation due to
impregnated dielectric.
• High dU/dt capability.
• Small dimensions.
• Safety approvals for worldwide use.
• The capacitors meet the most stringent
IEC humidity class, 56 days.
• The impregnated paper ensures
excellent stability giving outstanding
reliability properties, especially in
applications having continuous
operation.
TYPICAL APPLICATIONS
CONSTRUCTION
The capacitors are intended for use as
Multi-layer metallized paper. Encapsulated
interference suppressors in X1, X2 (across- and impregnated in self-extinguishing material
the-line) and Y2 (line-to-earth) applications. meeting the requirements of UL 94V-0.

Test voltage between
terminals
The 100% screening factory test is carried out at:
2150 VDC: PME271M and PME271E.
2700 VDC: PME271Y. The voltage level is selected to meet
the requirements in applicable equipment standards. All
electrical characteristics are checked after the test.
