The 1DFO, 2DFO, and 3DFO Series are designed to operate up to 500, 1000, and 1500 VRMS, respectively. Their low dissipation factor (DF) and stable temperature characteristics are well suited for operation at elevated frequency. Operating limits are governed by a suggested 30°C maximum case temperature rise as controlled by applied voltage and frequency dependent current. Power-rating charts covering the entire series provide operating guidelines for higher frequency applications.
FEATURES
• Ideal for High Voltage Switching to 100 kHz
• Low DF Minimizes Self Heating at High Frequencies.
• Application Voltages: 500, 1000 and 1500 Vac.
• Economical Alternative to Film Capacitors.
APPLICATIONS:
• Fluorescent Ballasts
• Industrial Electronic Systems
• Switching Power Supplies
• Snubber Networks
