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.
