Shunhai Technology's editor will provide parameter explanations for the in production models of Walter Electronics.
The resistance temperature coefficient (TCR) is a physical quantity that describes the degree to which resistance changes with temperature, usually in parts per million degrees Celsius (ppm/ ° C). It reflects the relative percentage change of the resistance value when the temperature changes by 1 ° C.
SMT resistors (thick film SMT resistors) are not unfamiliar to hardware R&D engineers or procurement engineers; Among the many model parameters of SMT resistors, there is a resistor that is quite special, which is the protagonist that Chip Brother needs to introduce -0 ohm resistor; Due to its unique resistance value, it is often used in special application scenarios in project circuit design; So, what are the circuit design techniques for a 0 ohm resistor? Hua Nian, let me give you some inspiration.
The impedance of a transmission line is the impedance received at the signal front (jump), which is an instantaneous impedance. So the impedance of the transmission line can also be seen as a resistor connected in series on the signal path.
In the early days, we all built our own power supply circuits, and now there are many integrated chips. DC-DC circuits are also ubiquitous in electronic products. This article shares some basic knowledge of DCDC circuit design with everyone. Concept and characteristics: DC-DC refers to a direct current to direct current power supply. It is a device that converts electrical energy from one voltage value into electrical energy from another voltage value in a DC circuit.
