Screw Terminal Aluminum Electrolytic Capacitors – PEH200 Series, +85°C
Mechanical Data
Polarity and Reversed Voltage
Aluminium Electrolytic capacitors manufactured for use in DC applications contain an anode foil and a cathode foil. As such, they are
polarized devices and must be connected with the +ve to the anode foil and the -ve to the cathode foil. If this were to be reversed then
the electrolytic process that took place in forming the oxide layer on the anode would be recreated in trying to form an oxide layer on
the cathode. In forming the cathode foil in this way, heat would be generated and gas given off within the capacitor, usually leading to
catastrophic failure.
The cathode foil already possesses a thin stabilized oxide layer. This thin oxide layer is equivalent to a forming voltage of approximately
2 V. As a result, the capacitor can withstand a voltage reversal of up to 2 V for short periods. Above this voltage, the formation process
will commence. Aluminium Electrolytic capacitors can also be manufactured for use in intermittent AC applications by using two anode
foils in place of one anode and one cathode.
Mounting Position
The capacitor can be mounted upright or inclined to a horizontal position.
Clamp Fixing
Clips must be ordered separately.
Stud Fixing
Nylon cap nut must be ordered separately. For the stud fixing insulated version, the outer insulation serves as lock washer.
Maximum tightening torque:
M8 = 3 Nm
M12= 8 Nm
Maximum chassis thickness 5 mm.
Screw Terminals
M5 x 10 according to DIN 41.248.
Maximum tightening torque = 2.5 Nm.
Must be ordered separately.
Recommended maximum connector thickness with delivered screw = 4 mm. M6 thread upon request.
Insulation Can
PEH200 is supplied with a polypropylene insulation can, thickness 0.8 mm. Voltage proof of the insulation sleeve: ≥ 4,000 VDC
PVC shrink sleeve only upon request.
