The Littelfuse TMOV
®
34S thermally protected varistor
series consists of a 34mm square format varistor element
(MOV) with an integral thermally activated element. This
element is designed to open in the event of overheating
due to abnormal overvoltage, limited current conditions.
Certain TMOV
®
34S varistor are offered with a "monitor"
lead which may be connected to signalling circuity to
indicate if the MOV has been disconnected from the circuit.
TMOV
®
34S varistor series offer quick thermal response due
to the close proximity of the integrated thermal element
to the MOV body. The integrated configuration also offers
lower inductance than most discrete solutions resulting
in improved clamping performance to fast over voltage
transients.

如何降低开关电源的EMI
开关电源的功率MOSFET安装在电路板上,由于电路板上MOSFET走线和环路存在杂散电容和寄生电感,开关频率越高,这些杂散电容和寄生电感更加不能够忽略。 由于MOSFET上的电压和电流在开关时会快 ......
