High Energy Industrial Thermally Protected
TMOV34S
®
Varistor Series
The Littelfuse Industrial TMOV34S series thermally protected varistor
represents a new development in circuit protection. It consists of a 34mm
square format varistor element ( MOV) with an integral thermally activated
element designed to open in the event of overheating due to abnormal
over-voltage, limited current conditions as outlined in UL1449 Feb. 1998
edition.The device has a third lead, an indicator lead, which may be used
to indicate that the MOV has been disconnected from the circuit. This lead
facilitates connection to monitoring circuitry. The TMOV34S devices offer
quick thermal response due to the close proximity of the integrated ther-
mal element to the MOV body. The integrated configuration also offers
lower inductance than most discreet solutions resulting in improved
clamping performance to fast over-voltage transients.

RC耦合中电阻电容+A、B、AB类功率放大
1.基本RC耦合放大电路 稳压电阻:为稳定偏置电压而设置 旁路电容: 阻断稳压电阻上的交流通过。不加还会影响到放大倍数,使放大倍数减小。 2.功率放大(使用变压器) ......
