Surface Mount Varistors
VP Series Plastic Encapsulated 85°C
Overview
KEMET's VP series of low and medium voltage plastic-
encapsulated varistors are designed to protect electronic
equipment against high voltage surges in the low and
medium voltage region. They offer direct surface mount
equivalents to leaded disc varistors of 5 and 7 mm sizes.
The thermoplastic encapsulation is non-flammable
according to the standard UL 94 V-0. Contacts are made of
tinned copper sheet.
These transient voltage suppressors cover an operating
voltage Vrms from 11 V to 300 V, featuring maximum surge
currents from 100 A to 1,200 A.
Applications
Typical applications include medical instruments, integrated
circuits and transistors, mobile communication, white
goods, entertainment electronics, lighting ballast, as well
as protection of low and medium voltage boards, remote
control and electrical counters and applications that are
exposed to humidity.
Benefits
• Surface mount form factor
• Operating ambient temperature of −40°C to +85°C
• Operating voltage range of 14 to 385 VDC
• Operating voltage (Vrms) of 11 V to 300 V
• Available case sizes: 3255 and 4032
• Dimensional and weight savings on the board
• Non-flammable thermoplastic encapsulation according to
the standard UL 94 V-0
• RoHS 2 2011/65/EC, REACH compliant
