ROHM a r\u00e9cemment d\u00e9velopp\u00e9 des r\u00e9sistances de shunt \u00e0 bornes larges, les LTR10L<\/a>, qui sont optimis\u00e9es pour de nombreuses applications dans les secteurs de l\u2019automobile, de l\u2019industrie et grand public. De plus, deux r\u00e9sistances de shunt de la s\u00e9rie MCR, destin\u00e9es \u00e0 un usage g\u00e9n\u00e9ral, viennent renforcer cette large gamme (MCR10L<\/a>\u00a0et\u00a0MCR18L<\/a>).
\nCes derni\u00e8res ann\u00e9es ont vu appara\u00eetre la n\u00e9cessit\u00e9 d\u2019un fonctionnement \u00e0 haut rendement du point de vue de la conservation de l\u2019\u00e9nergie, non seulement dans les applications aliment\u00e9es par batterie telles que les appareils mobiles et les v\u00e9hicules \u00e9lectriques, mais aussi dans les \u00e9quipements grand public et industriels \u00e9galement aliment\u00e9s par des prises \u00e9lectriques. Pour un rendement \u00e9lev\u00e9 et un fonctionnement optimal des appareils, il est important de d\u00e9tecter avec pr\u00e9cision des param\u00e8tres tels que le courant et la tension. Cela n\u00e9cessite des r\u00e9sistances de shunt combinant une haute pr\u00e9cision avec une d\u00e9tection de courant hautement fiable. Dans le m\u00eame temps, les fabricants d\u2019applications utilisant des densit\u00e9s de cartes plus \u00e9lev\u00e9es exigent des r\u00e9sistances de shunt encore plus petites. Pour r\u00e9pondre \u00e0 ces besoins, la nouvelle s\u00e9rie LTR10L offre la puissance nominale la plus \u00e9lev\u00e9e de l\u2019industrie et le meilleur coefficient de temp\u00e9rature de r\u00e9sistance (TCR) de sa cat\u00e9gorie dans un format compact de 0508 (0,5 pouce \u00d7 0,8 pouce) \/ 1220 (1,25 mm \u00d7 2,0 mm) qui contribue \u00e0 la fois \u00e0 une grande fiabilit\u00e9 et \u00e0 une miniaturisation plus pouss\u00e9e.
\nL\u2019am\u00e9lioration du mat\u00e9riau de l\u2019\u00e9l\u00e9ment r\u00e9sistif et l\u2019application de la m\u00e9thode de d\u00e9classement de la temp\u00e9rature aux bornes ont permis \u00e0 la LTR10L de fournir une puissance nominale de 1 W dans le format 0508, soit 88 % plus petite que les produits existants. En outre, une tol\u00e9rance de r\u00e9sistance de haute pr\u00e9cision de \u00b10,5 % a \u00e9t\u00e9 atteinte, ainsi que les meilleures caract\u00e9ristiques TCR et anti-sulfuration. Ces caract\u00e9ristiques les rendent id\u00e9ales pour les applications expos\u00e9es \u00e0 des conditions difficiles, y compris les stations de base de t\u00e9l\u00e9communications n\u00e9cessitant une grande durabilit\u00e9 et les phares LED d\u2019automobiles qui exigent une d\u00e9tection de courant de haute pr\u00e9cision ainsi qu\u2019une fiabilit\u00e9 \u00e0 long terme. D\u2019autre part, les s\u00e9ries MCR10L et MCR18L de r\u00e9sistances de shunt \u00e0 usage g\u00e9n\u00e9ral utilisent une structure d\u2019\u00e9l\u00e9ment et des mat\u00e9riaux am\u00e9lior\u00e9s pour augmenter la puissance nominale \u00e0 respectivement 0,5 W et 0,75 W, par rapport \u00e0 leur puissance nominale de s\u00e9rie conventionnelle (0,25 W). Une puissance nominale plus \u00e9lev\u00e9e permet les m\u00eames performances dans une taille plus petite, contribuant \u00e0 la miniaturisation du produit.<\/p>\n
