 Custom designed passives can be considered to be used after careful technical and economical analysis in volume manufacturing, if time-to-market and cost targets of the product(s) can be met.Therefore integrated passive devices are continuously technically and economically challenged by decreasing size, improving tolerances, improving accuracy of assembly techniques (like SMT, surface-mount technology) of system motherboards and cost of discrete/separate passive devices.Going forward discrete and integrated passives will complement each other technically.
