ORDERING INFORMATION
The varistors are available in a number of packaging
options:
• Bulk
• On tape on reel
• On tape in ammopack
The basic ordering code for each option is given in tables
titled Varistors on Tape on Reel, Varistors on Tape in
Ammopack, and Varistors in Bulk. To complete the catalog
number and to determine the required operating
parameters, see Electrical Data and Ordering Information
table.
Note
• Special lead-configuration as inside or outside crimped leads on
request.
FEATURES

APPLICATION
• Overvoltage and transient voltage protection
DESCRIPTION
The varistors consist of a disc of low-ß ceramic material with
two solid copper leads (H20 types only) or copper clad steel
wire. The wires have a matte tin plating. They are coated
with a layer of ocher colored halogen- free epoxy, which
provides electrical, mechanical and climatic protection. The
encapsulation is resistant to all cleaning solvents in
accordance with IEC 60068-2-45.
MOUNTING
The varistors are suitable for processing on automatic
insertion, cutting and bending equipment.
Typical Soldering
235 °C, duration: 5 s (Pb-bearing)
245 °C, duration: 5 s (lead (Pb)-free)
Resistance to Soldering Heat
260 °C; duration: 10 s max.
MARKING
The varistors are marked with the following information:
• Maximum continuous RMS voltage with - E suffix
• Series number (582, 583, 584, 585 or 586)
• Manufacture logo
• Date of manufacture (YYWW)
• Safety marks on VDRH10-14-20 types
INFLAMMABILITY
The varistors are passive non-flammable. The encapsulation
is made of flame resistant epoxy in accordance with
UL 94 V-0.
