R2 47k W (SC-105AA) (SC-89)
UMT3F
l Features
1) Built-In Biasing Resistors, R1 = R2 = 47k W. IN
2) Built-in bias resistors enable the configuration of GND
an inverter circuit without connecting external
DTA044EUB input resistors (see inner circuit). (SC-85)
3) The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing
of the input. They also have the advantage of l Inner circuit
completely eliminating parasitic effects. 4) Only the on/off conditions need to be set for operation, making the circuit design easy. 5) Complementary NPN Types :DTC044E series 6) Lead Free/Ro HS Compliant.

Frequently Asked Questions
How do the built-in bias resistors function?
They enable inverter circuit configuration without external input resistors, using thin-film resistors for complete isolation to allow negative biasing.
What extreme environments or applications should I avoid using this device in?
Do not use it in systems requiring extremely high reliability, such as medical instruments, aerospace machinery, or nuclear-reactor controllers.
What are the key electrical specifications and current limits?
The maximum collector current limit is -100 mA. Power dissipation varies between 150 mW and 200 mW depending on the specific model.
