This results in a possible maximum increase in diameter of 0.188 (4.763mm) for low resistance, 1.125 (28.575mm) O.D. core resistors and larger; 0.156 (3.969mm) for resistors with smaller diameter cores. On all high resistance units the increase is generally less than 0.125 (3.175mm). Other Core Sizes: Many other specials are available including cores with special inside diameter listed at right. 1-866-9-OHMITE • Int’l 1-847-258-0300 • Fax 1-847-574-7522 • www.ohmite.com • [email protected] 121 Cores with Non-standard I.D.
