Strontium titanate varistor is a symmetrical varistor made of strontium titanate electronic ceramics sintered at high temperature. It has excellent voltage and current nonlinear characteristics and high capacitance, can suppress surge voltage, and is particularly suitable as a carbon brush protection and spark elimination element for micro motors.
Features
High capacitance, good noise absorption effect in a wide frequency range.
It has a large voltage nonlinear coefficient, strong surge absorption ability and high reliability self-recovery ability.
The varistor voltage E10 temperature coefficient is small and positive.
Good welding resistance, small E10 change rate after welding. The volt-ampere characteristic has no directionality.
Application
Used for spark elimination and noise absorption of micro DC motors, which can increase the service life of carbon brushes.
In a DC motor, the current in the commutating coil reverses in a very short time, and the rate of change of the current over time is very large, and uncontrolled electromagnetic waves are generated. On the spectrum analyzer, it can be seen that the strontium titanate varistor can reduce the interference signal of each frequency band by 20dBµV/m or more, which is equivalent to suppressing more than 90% of the interference signal. The effect is obvious. Motors with varistors may not pass the EMC test, but after the varistor suppresses more than 90% of the electromagnetic interference of the motor, the user can further suppress the electromagnetic interference. In this way, the total cost of the whole product is often the smallest.
The selection of varistor is closely related to the voltage. It is hoped that users can actually measure and confirm the motor terminal voltage. If there is a large error between the measured voltage and the rated voltage, the varistor is selected according to the rated voltage, and its effect will be greatly reduced.
