BOURNS Road Dump Surge Protection Proposal

BOURNS Road Dump Surge Protection Proposal

Due to changes in international standards, the voltage range has been expanded and the testing conditions have become stricter. The protective element SM8SF-Q is compliant with the new standards and is a compact product.

The SM8SF-Q is ideal for those seeking a smaller size of 8.1X10.5X1.3mm and a lower profile compared to the competing product DO-218 size (10.5X16X5mm). It can be replaced using the same recommended pad layout as the competing product, allowing for a drop-in replacement without the need for PCB modifications. We also offer the same DO-218 type, so please consider it.

【BOURNS】Ceramic PTC - Outstanding delivery advantages◎

【BOURNS】Ceramic PTC - Outstanding delivery advantages◎

Compared to other companies' products, supply is possible within half the period. A quick reference table for equivalent products for replacement consideration is available!

Due to the recent rapid expansion of demand and the tightening of supply systems, it has become very difficult to obtain semiconductors and electronic components. Therefore, we would like to introduce products from BOURNS, a company with production bases around the world, which offers stable delivery times compared to other manufacturers. While competitors' lead times are extending, our research indicates that we can supply products in about half the time! We also have a wide range of equivalent products to those from other manufacturers, making it easy to consider smooth replacements! In addition, BOURNS offers a variety of components, including protective parts, so we encourage you to consider BOURNS products during this opportunity.
