Aluminum Electrolytic Capacitors - Accessories
(Vishay BCcomponents)
RESISTORS FOR TERMINAL MOUNTING
Resistors are used to balance the voltage over a series connection of screw terminal capacitors or to ensure discharge to a safe
voltage after power down. Vishay provides the CMS series of resistors, which are suited for direct mounting on the terminals of
screw terminal capacitors.
MOUNTING ACCESSORIES
CLAMPS FOR ST TYPES
To facilitate vertical mounting, a series of rigid clamps is available. These are made of zinc plated steel, chromium (III)
passivated, or stainless steel (Ø D = 76 mm).
The clamps have either two or three mounting lugs, may be easily slipped over the capacitor and then clamped with
a nut and bolt. Five types of clamps are available, one for each case diameter.
They are delivered without nuts or bolts.
To avoid damaging the insulation sleeve, do not overtighten the clamp screw.

NUTS AND WASHERS FOR STB-VERSIONS
When mounting with the bolt, which is an integral part of the case, standard metal M8 and M12 nuts and washers may be used;
the maximum permissible torque is 4 Nm for M8 nuts and 10 Nm for M12 nuts.
If insulated mounting is required, synthetic nuts and rubber washers are available; for these nuts the maximum permissible
torque is 2 Nm (M8) and 4 Nm (M12).
