Lead times increase for power management ICs

Lead times increase for power management ICs
Lead times and prices are rising for power management ICs (PMICs) while passives mostly remain stable apart from MLCC ceramic capacitors

The latest availability report from Sourceability highlights increasing lead times and process for the four main suppliers of power management IC (PMIC) semiconductor devices.

PMIC chips from STMicroelectronics, Texas Instruments, Infineon Technologies and Analog Device are all seeing lead times from 16 to 20 weeks, rising to 36 weeks for some parts from Infineon. This is set to extend in the next three months as well. Prices are also increasing across the board for parts from ST says the report.

Most of the lead times and pricing for passive devices is stable, apart from the throny area of multilayer ceramic capacitors. Supplies from Samsung, TDK, Yageo and Walsin are all seeing longer lead times, typically 20 to 30 weeks and mostly set to increase, as are prices. The only MLCC supplier seeing stable pricing over the next three months was TDK.

Tantalum capacitors from Vishay are stable in lead times and pricing, while most film and aluminium capacitors are all seeing increased lead times. Transformers, ferrites and EMI filters are all stable in lead times from 8 to 22 weeks and in pricing.

The report is generated from the company’s SourceEngine real time tool which covers the major suppliers and so gives a snapshot of component availabiliity.
