BLM18S Series (0603 Size)<br />
■ Features<br />
1. Low <strong>DC</strong> Resistance/Large Rated Current<br />
2. BLM18S series can be used in high current circuits<br />
due to its low <strong>DC</strong> resistance.<br />
It can match power lines to a maximum of 6A <strong>DC</strong>.<br />
3. Ni+Sn plating structure of the extenal electrodes<br />
provides excellent solder heat resistance.<br />
