HD/HE Type Datasheet

High Voltage Ceramic Capacitors
HD/HE Type – Type N4700 – Maintenance Only
FEATURES
•
•
•
•
Disc capacitor, type N4700
Excellent capacitance vs voltage characteristic
Low dissipation factor
Good behavior vs frequency
APPLICATIONS
• AC voltage dividers at industrial frequency
• High frequency coupling and decoupling
• Other special HV applications
TECHNOLOGY
• HD range: Molded type with fixtures M5 or M8
• HE range: uncoated type without fixtures
(silvered ceramic) disc
• Marking: on each part:
TPC – Reference – Capacitance – Rated voltage
• Delivery mode: bulk in carton box
• Dielectric Type: N4700 class (see typical curves on page 13)
