Product Description
Surface Electrode Type SrTiO3 Strontium Titanate Ring Varistors 1.5~60V For Micro DC Motor
I Description Of The SrTiO3 Strontium Titanate Ring Varistors
Ring varistors are used in a wide range of applications from micro motor noise absorption to the
protection of circuit contacts.
Ampfort has greatly improved the electrical and physical performances of these varistors to meet
the latest demands. This varistor line covers the traditional shapes and dimensions as well as the
more varied and specialized applications.
Super strontium Titanate Varistor are symmetrical voltage-dependent Non-linear resistors that are made primarily of strontium titanate and sintered at a high temperatures. They have excellent non-linear coefficient characteristics of voltage (£) and high capacitance ( C ) for reducing transient voltage . These varistors are especially suitable for absorbing micromotors spark noise and protecting the micromotors contact point.
II Features Of The SrTiO3 Strontium Titanate Ring Varistors
• Conductor ceramic is made of titanium oxide and strontium
• Used in the range of low voltage E10 (1.5 to 60V)
• Wide capacitance, absorb the noise in a wide frequency range
• Excellent non-linearity voltage High capability to absorb surge and high reliability to recover itself
• With the function both of capacitor and varistor Can absorb forward short pulse
• Small temperature coefficient of voltage E10
• Excellent soldering resistance, small E10 changing after soldering
• 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.

V PHYSICAL PERFORMANCES Of The SrTiO3 Strontium Titanate Ring Varistors
• 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.
VI PRODUCT LINEUP Of The SrTiO3 Strontium Titanate Ring Varistors
• The varistors in this series come in a wide range of dimensions and so can be accurately used for almost all motors.
• This lineup includes side-surface electrode varistors that can be used with ultra-compact micro motors.
