ST is using its semiconductor and MEMS technology expertise to integrate commonly used circuit elements such as passive filters, ESD suppressors and wireless baluns in a much smaller size than the state-of-the-art discrete passive devices available in the market. The tolerance and stability of these integrated passive devices from ST is better than conventional discrete components, as claimed by ST. The smaller and thinner integrated passives, which can perform better than discrete devices will be lot more preferred by electronic design engineers, who are interested in saving space.
The new devices includes the world’s smallest (as claimed by ST) single-line Transient-Voltage Suppressor, the ESDAVLC6-1BV2, in a 01005 surface-mount package to protect sensitive circuitry against hazardous voltage surges. ST is also introducing the first five members of its new ECMF family of common-mode filters embedding ESD protection. These are built using advanced silicon technology and are offered in ultra-thin packages only 0.55mm high.
ST says another new member of it's IPD (Integrated Passive Device) family, the BAL-NRF01D3 ultra-miniature wireless balun, has already enabled ST’s customers to boost the performance of their low-power wireless solutions and save up to 90% of the pc-board space occupied by discrete antenna-matching and harmonic-filtering components.
The BAL-NRF01D3 is in mass production in a 5-bump flip-chip package, priced from $0.18 for orders over 5,000 units. The ECMF common-mode filters are also in mass production, priced from $0.16 (ECMF02-2BF3) for orders over 1,000 units. The ESDAVLC6-1BV2 Transient-Voltage Suppressor is priced from $0.10 for orders over 1,000 units.
