UHV-221A Datasheet, PDF (1/3 Pages) TDK Electronics – Ultra-high Voltage Ceramic Capacitors Molded Type with Metal Terminals

(1/3)
Ultra-high Voltage Ceramic Capacitors
Conformity to RoHS Directive
Molded Type with Metal Terminals UHV, FHV Series
CLASS 2 HIGH DIELECTRIC
DC. 20 TO 50kV: UHV-1A TO 12A, 221A TO 253A TYPES
DC. 15 TO 50kV: FHV-1AN TO 12AN, 153AN TYPES
TDK UHV and FHV series high voltage ceramic capacitors feature
low dissipation and excellent voltage-capacitance characteristics
using patented strontium titanate for dielectric material. They are
epoxy-encapsulated to meet requirement of high voltage applica-
tions.
FEATURES
• Small size.
• Low dissipation factor.
• Excellent voltage-capacitance characteristics.
• Screw terminals for easy mounting.
• FHV series: High capacitance and low temperature characteri-
stics of capacitance.
APPLICATIONS
High voltage power supplies, laser equipment.
