Circuit design, component placement, PWB trace size and thickness, airflow Low profile, high current power supplies and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application DC/DC converters in distributed power systems (1) DC current (A) that will cause an approximate T of 40 C (2) DC/DC converter for field programmable gate array DC current (A) that will cause L to drop approximately 20 % 0 (3) DC current (A) that will cause L to drop approximately 30 % 0 (FPGA) DIMENSIONS in inches millimeters 0.394 0.005 Typical pad layout 10 0.13 0.460 11.68 0.394 max. 0.252 max. 0.135 0.010 0.155 10 max. 6.40 max. 3.4 0.3 3.94 0.155 0.010 0.090 3.9 0.3 0.404 0.010 2.29 10.25 0.25 Note DCR measured at locations indicated by on drawing DESCRIPTION IHVR-4025JZ-3Z 0.10 H 20 % EZ e3 MODEL INDUCTANCE VALUE INDUCTANCE TOLERANCE PACKAGE CODE JEDEC LEAD (Pb)-FREE STANDARD GLOBAL PART NUMBER I H V R 4 0 2 5 JZ E Z R 1 0 M 3Z PRODUCT FAMILY SIZE PACKAGE INDUCTANCE TOL.
