4500 Series www.murata-ps.com Shielded Surface Mount Power Inductors SELECTION GUIDE S Inductance (10kHz, 0.1VAC) Order Code RoHS compliant 00.28μH 28 H tto 11.0mH 0 H Up to 8A IDC Bobbin format Surface mount Integral EMI shield Compact size Tape and reel packaging UL 94V-0 materials J-STD-020-C reflow DESCRIPTION The 4500 series is a lower profile version of our 4600 series range of bobbin-wound, shielded inductors. They are suitable for power-line filtering found in consumer electronics such as desktop computers, LED applications and GPS systems, as well as in a vast range of industrial and telecom applications including network hubs, bridges & routers, and high frequency wireless communication devices. These surface mount inductors are extremely compact and have an integral shield, making them useful in EMI sensitive applications. 45281C 45541C 45102C 45152C 45222C 45332C 45472C 45682C 45103C 45153C 45223C 45333C 45473C 45683C 45104C 45154C 45224C 45334C 45474C 45684C 45105C DC Resistance Nom. μH Max.
