BC Components
Varistors
Product specification
2322 592 to 2322 595
FEATURES
• Zinc oxide disc, epoxy coated
• Straight leads
• Straight leads with flange
(2322 592 and 593 series only)
• Kinked leads.
APPLICATION
• Suppression of transients.
DESCRIPTION
The varistors consist of a disc of low-β
ceramic material with two tinned solid
copper leads. They are coated with a
layer of ochre coloured epoxy, which
provides electrical, mechanical and
climatic protection. The
encapsulation is resistant to all
cleaning solvents in accordance with
“IEC 60068-2-45”.
MARKING
The varistors are marked with the
following information:
• Maximum continuous RMS voltage
• Series number (592, 593, 594 or
595)
• Manufacturers logo
• Date of manufacture.
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 3, 4 and 5.
To complete the catalogue number
and to determine the required
operating parameters, see Table 7.
MOUNTING
The varistors are suitable for
processing on automatic insertion
and cutting and bending equipment.
Varistors with flanged leads provide
better positioning on printed-circuit
boards (PCB) and more accurate
control over component height. This
is important for hand mounting and
automatic insertion techniques;
see Fig.4.
Soldering
≤240 °C; duration ≤5 s.
Resistance to heat
≤260 °C; duration ≤5 s.
INFLAMMABILITY
The varistors are non-flammable.
