Riverside, California – September 23, 2021 – Effective March 19, 2022, Bourns will change the inductor core, shield and winding design for the Model PM7032S and SRR7032 Series Shielded Power Inductors to improve the component’s quality and reliability.
■ All part numbers of PM7032S and SRR7032 series: There will be a new core design that is constructed without the round slots to increase inductance stability.
■ All part numbers of PM7032S and SRR7032 series: There will be a new shield design that includes eight protrusion lines along the inside diameter of the shield to facilitate consistent gapping between the core and shield.
■ Select part numbers with inductance values 47 – 1000 μH of PM7032S and SRR7032 series: The wire insulation thermal class will be upgraded to 180 °C from 150 °C.
■ Select part numbers with inductance values 2.2 – 33 μH of PM7032S and SRR7032 series: The winding will change from multiple wire strands to a single strand in larger wire diameter to increase manufacturing efficiency. The inductor DC Resistance (DCR) specification remains unchanged.
