RES-EY Datasheet, PDF (1/2 Pages) Ohmite Mfg. Co. – Suitable for automatic machine insertion
EY Series
Ceramic Composition
10% Tolerance
F e a t u r es
• Suitable for automatic machine insertion
• Ideal for high energy/high peak power applications
• Products with lead-free terminations meet EU
RoHS requirements
• Higher reliability against disconnection compared
to wirewound resistors and film resistors
