An RS-485 protection circuit has to preserve the bus's -7 V to +12 V common-mode operating window while surviving the transient tests that apply to the finished product. An asymmetrical 7 V/12 V TVS array is a strong starting point, but a TVS part number by itself does not establish an IEC 61000-4-5 system rating. The transceiver, coupling network, series impedance, surge-return path, PCB layout, and any coordinated primary stage all affect the result.

The 1N5822 is a Schottky diode that has very low forward drop voltage VF which makes it ideal for fast switching applications at lower current ratings.

Although LR44 and 357 batteries look the same shape, they perform differently. The LR44 is an Alkaline Zinc Manganese button cell battery, whereas, the 357 is a silver oxide button cell battery. Today, this article is going to explain what differences lie in and whether they can interchangeable.

According to the COMSAN battery standard, the sizes of the CR2450 and CR2032 are different. CR refers to lithium manganese round batteries, 2032 means 20 mm in diameter and 3.2 mm in thickness, and 2450 means 24 mm in diameter and 5 mm in thickness. Although they are both lithium batteries, can they be interchangeable? In this article, we will discuss whether CR2450 and CR2032 are interchangeable.
