Low-Ohmic High Power Chip Resistors for Current Detection Applications ROHM Semi conductor has recently announced a new series of resistors called the LTR50. These resistors come in a compact 2550 size (2.5mm × 5.0mm × 0.55mm) with a wattage rating as high as 2W and resistance values between 10mΩ to 910mΩ. These small package resistors comes in high wattage rating and also helps in improving energy saving and reducing the size of the circuit… |

Pull Up and Pull Down ResistorWhat is Resistor?
Resistors are current limiting devices with are used abundantly in electronics circuits and products. It is a passive component which provides resistance when current flow through it. There are many different types of resistors. Resistance is measured in Ohm with a sign of Ω. What are Pull-up and Pull-Down… |

Overvoltage Protection Circuit Protection circuits, like reverse polarity protection, short-circuit protection, and over/under voltage protection, are used to protect any electronic appliance or circuit from any sudden mishap. Generally fuse or MCB is used for overvoltage protection. Here in this circuit, we will build a simple overvoltage protection circuit without using a fuse. … |

Voltage Regulator Circuits Voltage Regulator, as the name suggests, is a circuit that is used to regulate the voltage. Regulated voltage is a smooth supply of voltage, free from any noise or disturbance. The output from the voltage regulator is independent of load current, temperature, and AC line variation. Engineers can create reliable power supply systems with the aid of these voltage… |

Solenoid Driver Circuit Solenoids are very commonly used actuators in many process automation systems. There are many types of solenoids. For instance, there are solenoid valves which can be used to open or close water or gas pipelines, and there are solenoid plungers which are used to produce linear motion. One very common application of a solenoid that most of us would have come across is the… |

Voltage Controlled Oscillator (VCO) Most of the consumer electronic devices around us, such as mobile phones, TVs, Radios, and MP3 players, are a combination of Digital and Analogue electronics. Wherever wireless transmission/reception, or audio signals are involved in an electronic design, we will need periodic oscillating electronic signals. These signals are called Oscillating signals and are very useful in… |

RC, RL and RLC Circuits The entire range of electronic components can be divided into two broad categories: active components and passive components. The Passive components include the Resistor (R), the Capacitor (C) and the Inductor (L). These are the three most used components in electronics circuits, and you will find them in almost every application circuit. These three components together in… |

DC Circuit TheoryWhat is DC?
In elementary school, we learned that everything is made by atoms. This is a product of three particles: Electrons, Protons and Neutrons. As the name suggest Neutron does not have any charge whereas Protons are positive and Electrons are negative. In atom, electrons protons and neutrons stay together in a stable formation, but if by any… |

Passive High Pass Filter Previously, we discussed the Passive Low Pass Filter; now it is time to look into the passive high pass filter. A passive high pass filter is an electronic circuit that allows high-frequency signals to pass while blocking low frequencies below a predetermined cutoff point. Same as before, if you look into the name, it shows “Passive”, “High… |
