Max charge energy is defined as the maximum charged up energy value of over 95%. The capacitance is calculated as the following formula. J=CV^2/2 C: capacitance, V: peak voltage Note: The criteria of the standard for the maximum charged up energy value of over 95%. If there is the difference between our definition and yours, could you ask us free? Operating temperature range is -20 to +85°C.

It is able to integrated circuit for protection from inrush current suppression with POSISTOR r and relay or semiconductor switch as thyristor. c Features 1. Protection against overcurrent situations 2. Automatic reset from protective trip mode 3. Space-saving 4. Various characteristics to meet a suitable resistance value c Applications POSISTOR r is an integrated solution to work as both current limit resistor and overcurrent fuse. It works as a stable resistor in normal operation and products itself against overcurrent situation. It can be replaced from normal resistor or the resistor with temperature fuses solution as Fig.1. Fig.1 POSISTOR r works as normal resistor in normal condition, and it works as protector against over current situation on the circuit. 1. High-power switching power supply (LCD TV) 2. The power supply for inverter on outside unit for Air-conditioner 3. The power supply for inverter type fluorescent lamp 4. Other SW type power supply Load POSISTOR r + - Load + - |
