• F39-EJ1070-D Accessory
• Application Field
• The F39-EJ1070-D is an Arlon circuit component of an electronic device or appliance, and can be found in many modern electronic devices. Common uses of the F39-EJ1070-D include: microprocessor control systems, frequency synthesizers, communication equipment, multimedia applications, personal computers, high frequency hardware, consumer electronics, and industrial components.
• Working Principle
• The F39-EJ1070-D utilizes a combination of resistors, diodes, and capacitors to reduce external electromagnetic interference and power supply noise in sensitive electronic components. This component operates using two distinct methods called “pull-up” and “pull-down”. Pull-up is when a transistor (or a group of transistors) increases the current flowing through a circuit element while Pull-down works in the opposite manner allowing a transistor (or group of transistors) to decrease the current flow.
• The F39-EJ1070-D also utilizes a filtering method to reduce power supply noise and external electromagnetic interference. This is done through the terminal end of the component that is connected to the power line. First, the AC portion of the power is disconnected from the DC portion of the power, then the AC portion is filtered out. This filtering action reduces any voltage fluctuations or sags, which can lead to breakdowns in the circuit. In addition, the F39-EJ1070-D also limits the amplitude and frequency ranges of the power supply noise and EMI, so that it does not interfere with the normal operation of the electronic device.
• Lastly, the F39-EJ1070-D has a built-in protection feature that prevents the component from over current conditions. This protection feature works by reducing the current going through the circuit component when currents exceed the maximum specified level, thus protecting the component from destruction.
