Varistors(SrTiO )

For Micro-motors

VAR-18 Series

Ring varistors are used in a wide range of applications from micro

motor noise absorption to the protection of circuit contacts.

TDK has greatly improved the electrical and physical perfor-

mances of these varistors to meet the latest demands. This varis-

tor line covers the traditional shapes and dimensions as well as the

more varied and specialized applications.

• The temperature characteristics of the varistor voltage (E10

value) are positive. This prevents the varistor voltage from

decreasing at high temperatures and from large currents flowing

through the varistor. Therefore, these varistors remove design

obstacles by eliminating the need for setting the room

temperature varistor voltage (E10 value) higher—a measure that

compromises noise reduction levels.

• Furthermore, the VAR-18 series has also eliminated the problem

of the noise level being amplified at low-temperatures and

having a negative impact on the life of the motor.

• Because the VAR-18 series has the same large capacitance as

the conventional varistors, it has excellent functions to eliminate

and control motor noise in high frequency bands.

P: Plane

• Because copper electrodes are used and the heat resistance of

the ceramic elements has been improved, there is no concern

for electrode erosion or thermal crack even at the higher

soldering temperatures that are used in lead-free soldering.

• The ceramic element has excellent flexure strength as is suitable

for automatic motor assembly.

• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific

bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.

• All specifications are subject to change without notice.
