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.

[Help] What is the maximum baud rate of the serial port of MSP430F149?
MSP430F149 currently uses 32768 crystal oscillator.Its two serial ports can only reach 9600 baud rate,which is far from meeting the design requirements.So I want to ask:If we want to increase its baud...
