High Voltage Ceramic Capacitors
HT/HU Types - Type I
FEATURES
APPLICATIONS
• Disc capacitor, type I
• Two available versions:
• High voltage coupling
• Low reactive power
- HT: Molded type with connections
• High voltage tuning
• High stability vs temperature
• No capacitance change vs voltage
- HU: Uncoated type without
connections (silvered ceramic)

Hardware supplied for capacitor mounting
In order to improve capacitor mounting, connec- 2 x screws TCB M5 L8
tions ends are designed with two flats. Thus, tight- or TCB M8 L12
ening torque is only applied on the screw (consult 2 x washers
chart above for torque “S” value).
