Patch rejection selection is very important for the stability and performance of the circuit, ROHM company as a well-known electronic components manufacturer, its 0402, 0603, 0602 series of patch rejection is widely popular in the market, the following Shunhai technology will provide readers with a detailed ROHM patch rejection selection guide.
ROHM patch exclusion size selection
ROHM 0402/0603/0602 series of patch resistance, size from 1005×2mm to 1605×8mm, in the selection, the first thing to consider is the size of the available space on the circuit board. If space is limited, choose the smaller 0402 or 0603 specifications; If you have enough space, you can choose the slightly larger 0602 specification for better thermal performance and power carrying capacity.
ROHM patch rejection rated power consideration
The rated power range of ROHM patch rejection is between 0.031W and 0.063W. When selecting, the required power rating should be determined according to the power requirements in the circuit. If the current through the circuit is large or the working environment temperature is high, the rejection resistance with higher rated power should be selected to prevent damage due to overheating.
ROHM patch rejection resistance value selection
The choice of resistance value is directly related to the working state of the circuit. The ROHM patch has a wide range of resistance values, from 1Ω to 1MΩ. In the selection, the required resistance value should be determined according to the circuit design requirements. At the same time, it is also necessary to consider the accuracy of the resistance value and the temperature coefficient to ensure the stability of the circuit in different working environments.
ROHM patch exclusion model selection
There are many models of ROHM patch block, such as MNR02M0APJ, MNR04M0APJ, MNR12E0APJ, etc., the main difference between different models is the size, power and resistance value and other parameters, in the selection, should be based on the above three aspects of consideration to choose the appropriate model, but also pay attention to the suffix in the model, such as "000", etc. These suffixes usually indicate a specific package or performance level.
