VAR-18 Series  
EMC Components  
Varistors(SrTiO3 System)  
For Micro-motors  
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.  
PHYSICAL PERFORMANCES  
• 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.
