APPLICATION
• Overvoltage and transient voltage protection
DESCRIPTION
The varistors consist of a disc of low- ZnO ceramic material
with two solid copper leads (S20 types only) or copper clad
steel wire. The wires have a matte tin plating. They are
coated with UL 94 V-0 approved ocher colored halogen-free
epoxy, which provides electrical, mechanical and climatic
protection.
MOUNTING
The varistors are suitable for hand-mounting (bulk) or
automatic pick and place mounting (tape on reel or fanfold).
The parts can be soldered by hand or wave soldering.
Pin-in-paste reflow soldering is not recommended. Bending
of the leads for different angle placement is not
recommended.
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
• Series numbers
- 592 for VDRS05
- 593 for VDRS07
- 594 for VDRS10
- 595 for VDRS14
- 596 for VDRS20
• Safety marks on VDRS10-14-20 types
• Manufacturers logo
• Date of manufacture (YYWW)
INFLAMMABILITY
The varistors are passive non-flammable.
The encapsulation is made of flammable resistant epoxy in
accordance with UL 94 V-0.
