FMMT491TA Frequently Asked Questions (FAQ)
-
A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
-
The FMMT491TA requires a minimum of 10mA of quiescent current to ensure proper biasing. A resistor divider network can be used to set the bias voltage to 2.5V.
-
The maximum power dissipation for the FMMT491TA is 1.5W. Exceeding this limit can cause the device to overheat and potentially fail.
-
While the FMMT491TA is suitable for high-frequency applications, it's essential to ensure that the device is properly bypassed and decoupled to minimize ringing and oscillations.
-
Handling the device by the body or using an ESD wrist strap can help prevent ESD damage. Additionally, using ESD protection devices such as TVS diodes can provide added protection.
