PME294 Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – EMI suppressor, class Y1, metallized paper

PME294
• EMI suppressor, class Y1, metallized paper
• Safety capacitor, ceramic replacement
• 470 – 4700 pF, 440 VAC, +115 °C, test voltage 4000 VAC 60 s
• Self-extinguishing encapsulation. The
material is recognized according to
UL 94 V-0.
• Very precise positioning of the leads in
relation to the case giving efficient
utilisation of PC board space.
• Excellent self-healing properties.
Ensures long life even when subjected to
frequent overvoltages.
• High dU/dt capability.
• Good resistance to ionisation due to
impregnated dielectric.
• 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
Safety capacitor for bridging of double or
reinforced insulation applications requiring
voltage test up to 4000 VAC 60 seconds.
PME294 can be left in place during this test.
Multi-layer metallized paper. Encapsulated
and impregnated in self-extinguishing material
meeting the requirements of UL 94V-0.
