Product Recommendation Maker Dynamics Applications

Recommended protection scheme for DC12V power supply Hnstshop recommends: Socay's DC12V power supply protection scheme. Hnstshop is an authorized distributor of the Socay brand, providing complete purchasing and FAE technical support, as well as circuit rectification and testing laboratories. This article will recommend its DC12V power supply protection scheme and product selection application. The relevant products recommended in this article include SC3E5-90LSMD, SC3E6-90MM, SMBJ15CA, ceramic gas discharge tubes, and TVS transient suppression diodes.

What are the measures for surge suppression? The reasons for generating surges are multifaceted, and surges are a type of spike pulse with high rising speed and short duration. Overvoltage in the power grid, switch ignition, reverse voltage, static electricity, and motor/power supply noise are all factors that cause surges. And surge protectors provide a simple, economical, and reliable protection method for power surge protection of electronic devices.

Ethernet POE protection scheme Hnstshop provides a comprehensive Ethernet POE protection solution. Socay Electronics is a professional protection period manufacturer that provides Ethernet POE one-stop protection solutions. Ceramic gas discharge tubes, ESD electrostatic protection tubes, and TVS transient suppression diodes will be used in the POE protection scheme. Below is a detailed explanation of the SOCAY brand's POE protection scheme.

SLIC interface protection scheme Recommended by Hnstshop: SLIC interface protection plan. Hnstshop acts as the agent for Shuokai's entire series of products. Shuokai is a product of ESD, TVS, TSS, etc. SLIC, abbreviated as user interface circuit, refers to the analog user line interface circuit of a programmable switch, which refers to the interface circuit between the switch and the user computer. The analog interface of SLIC is usually a two line telephone line, and the lines are mostly outdoors. At the same time, due to the characteristics of SLICJ itself, it is exceptionally sensitive to external interference. Therefore, it is necessary to provide surge and static electricity protection for SLIC chips.
