STMicroelectronics to Release Super LED Mobile Phone Flash

This week STMicroelectronics announced the launch of a flash module that will have a significant impact on the image quality of low-light photo cameras and smart phones. This model, STCF4, can dramatically increase the power of LED flashes with less than a few watts to over 40 W. Its power derives from the MOSFET (Metal Oxide Semiconductor Field Effect Transistor) high-current switch and a super capacitor, which allows the mobile phone to bid farewell to the xenon flash lamp to achieve energy saving while bursting out of super bright light.

While being a flash, it can also be fixed to one of the eight brightnesses and used as a flashlight. This module will begin mass production in March this year.

Resistor (Resistor) commonly known as resistance directly in our daily life.It is a current limiting element. When the resistance is connected to the circuit, the resistance value of the resistor is fixed, usually two pins.Fixed resistors are those whose resistances cannot be changed.Resistance variable is called potentiometer or variable resistor.The ideal resistor is linear, that is, the instantaneous current through the resistor is proportional to the applied instantaneous voltage.Variable resistor for partial pressure.On the exposed resistor body, one or two movable metal contacts are pressed tightly.The contact position determines the resistance between any end of the resistance body and the contact.
