钛酸锶环形压敏电阻器
STRONTIUM  TITANATE  RING  VARISTOR
特性
用途
本元件由钛酸锶烧制而成。
用于低压范围 =3 ̄30V
10
具有大电容量(10 ̄15nF),可在甚宽的
频率范围内吸收噪音。
具有较大的电压非线性系数α=3 ̄10)
吸收浪勇能力强,而且具有高可靠性复
自复原能力。
具有压敏和电容复合功能,对前沿短的
脉冲具有良好的吸收效果。
压敏电压温度系数小。
10
耐焊接性好,焊接后变化率小。伏安
10
特性无方向性。
用于小型马达的火花消除和噪音吸收
及超低压线路保护。
Conductor cermaic is made of 
titanium oxide and strontium.
Used in the range of low voltage 
10=3 ̄30V.
Wide capacitance (10 ̄150nF),
absorb the noise in a wide fre-
quency range.
Excellent  non-linearity voltage
α=3 ̄10); High  capability  to 
absorb surge and  high reliabi-
lity to recover  itself.
FEATURES
With the function both of capacitor 
and varistor.It can absorb forward 
short pulse.
Small temperature coefficient of voltage E
10
Excellent soldering-resistance, small E10 changing after soldering.
APPLICATIONS
Eliminates sparks between governor contact and commuters and 
brashes, absorbs  noise  in  small  motors
