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.  
• High dU/dt capability.  
• Good resistance to ionisation due to  
impregnated dielectric.  
• 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.  
• 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.
