Base Theory Low ESR Tantalum Capacitors Make a Difference in Circuit Designs By Charles Pothier

Eltronicschool. - There are many electronic circuit design that use capacitor component in its design. Capacitor can be use as filter, couppling, and another function again. One kind of capacitor is tantalum capacitor that can be used in many different circuit design.

Two primary functions that tantalum capacitors are ideally suited for are bulk energy storage and waveform filtering.

In here we will discuss about base theory of capacitor specially in topic Low ESR Tantalum Capacitors Make a Difference in Circuit Designs that written By Charles Pothier. Base on him paper that Low ESR tantalum capacitors can improve circuit power efficiency, reduce heat generation for the circuit, and increase low-term reliability.

When choosing a capacitor for any application, there are a few key characteristics that must be understood in order to analyze its suitability for the circuit. In a simple capacitor equivalent circuit model, there are three key characteristics that affect circuit performance: capacitance, equivalent series resistance (ESR), and inductance. The magnitude of these elements - and how they change over temperature, frequency, and applied voltage - are different for each capacitor technology.

In this application note, we will examine the ways in which ESR in tantalum capacitors affects circuit performance. ESR is the sum of all of the purely resistive contributors to the capacitor's impedance. As such, it is the characteristic that creates losses due to heating. It also affects the magnitude of charge and discharge currents as the capacitor does its work.

In a solid tantalum capacitor, the components that contribute to ESR are the resistivity of the:

  1. Solid electrolyte system (MnO2)
  2. Dielectric layer (Ta2O5)
  3. Terminations, lead frames, and other elements that provide connection to the PCB


Solid tantalum capacitor manufacturers can make improvements in physical design and materials that reduce the overall ESR of the capacitor. These lower ESR capacitors will lead to reductions in heat generation within the capacitor, thus improving overall circuit efficiency and long-term reliability. Reductions in ESR will also improve the capacitor's ability to supply higher currents during charge and discharge cycles to improve circuit performance. Typical impedance (Z) and ESR data for a range of popular values are shown in Table 1. above

Using popular modules like Arduino, Ultrasonic sensor, and some of resistor and LEDs, we can build the system or device which can detect and indicate the fuel level in the vehicle.

In here we will show you one project how to build fuel level indicator based on Arduino Uno that can detect the various fuel level using ultrasonic sensor and transmitted to the atmosphere and recieved to indicate using LED light. Transmitter and reciever modul that will be used in this project is nRF24L01 wireless Tx/Rx module.

Description

Circuit schematic like in Figure 1 and Figure 2 above is transmitter and reciever of ultrasonic fuel level indicator based on Arduino. There are two parts of this circuit, these are transmitter and reciever with the same component in tow part is nRF24Lo1 wireless Tx/Rx module.

How it works

Accordingly Homemade Circuit site describe there are a pair of ultrasonic sensors in the module. One senor sends the ultrasonic frequency or the wave towards the fuel surface. The waves collide with the fuel surface and reflect back towards the module. The reflected ultrasonic waves are captured by the second sensor unit, and sent to the Arduino.

The Arduino compares the reflected ultrasonic time with the reference time of the tank "full height" and creates an estimation of the instantaneous height or the level of the fuel.

The information is then encoded and forwarded it to the nRF24L01 wireless module. The nRF24L01 module finally converts the code into RF signal and transmits it into the atmosphere for the receiver unit to capture the signal.

Circuit Schematic Mains Power Failure Alert Based on CMOS IC CD4060BE

Eltronicschool. - One purpose of main failure alert circuit designed is to protect a stock and equipment from damage. This device will give you information from the alerting when something problem and protect the electricity fail.

Although there are many main power power sold in the market but you also can make it easily using simple electronic circuit like in Figure 1 below. You only using main component CMOS IC CD4060BE to build this circuit. 

Circuit Schematic

Component Part
  1. CD4060BE CMOS IC
  2. Resistors
  3. Capacitors
  4. Photocoupler PC817B (OC1)
  5. Zener Diode
  6. LED
Description

Circuit schematic like shown in Figure 1 above is Circuit Schematic Mains Power Failure Alert Based on CMOS IC CD4060BE. Accordingly of Electroschematics site describe that the core component of the design given here is one revered 14-stage ripple-carry binary counter/divider and oscillator CMOS IC — CD4060BE (IC1). As shown in the schematic, components R3 and C2 set the clock frequency of IC1 close to 10 Hz, and there’s a blue indicator (LED1) to show the clock activity. The Q4 output (Pin 7) of IC1 drives an active piezo-buzzer (PZB1) and a red indicator (LED2) through a small NPN transistor S8050 (T1). The circuit also includes a standard, on-rechargeable, 6F22 9-V battery (BAT) in power supply and a low-voltage slide switch (S1) as the master power on/off switch.

The front end of the design is a simple AC230V mains presence sensor built around one popular photocoupler PC817B (OC1). The output of OC1 is routed to the “master-reset” terminal (Pin 12) of IC1 to disable its clock operation when the AC mains supply is available (standby mode). There are so many ways to convert an AC voltage into a DC voltage required by a photocoupler, and traditionally, this has been done with a step-down transformer. However, a low-cost alternative — capacitive power supply — is employed here because it’s more cost-effective and significantly smaller. In the AC mains presence sensor, a 100-n/250-V AC capacitor (C5) is the key element, and the 100-Ω resistor (R3) is to limit inrush current. The remaining components include a rectifier (D2), buffer (C4), and a protector (ZD1). The 5.1-V Zener diode (ZD1) is added intentionally to deter the blowup of C4 in case of an open-load condition at the output of the capacitive power supply (all resistors are ¼-W type).
