contributing to further minimize the overall footprints.
The industry’s smallest* package and high PSRR minimize
automotive camera modules!
The industry’s smallest* package minimizes camera modules.
S-19255 Series comes in a 1.0mm square HSNT-4(1010)B, the industry’s smallest* package. The use of HSNT-4(1010)B package with outer leads facilitates mounting, ensures high mounting strength and permits automated visual inspections after mounting.
S-19255 Series accommodates the demand for smaller camera modules to enable installation of the ever-growing number of camera modules that systems such as Advanced Driver Assistance (ADAS) and Autonomous Driving (AD) require.

High PSRR over a wide frequency range simplifies circuits and lowers costs
S-19255 Series provides high PSRR over a wide frequency range with a rejection rate of 80dB typ. (f = 1.0kHz) and 50dB (f = 100kHz). This means that it requires no circuits to reduce noise, which simplifies circuits and lowers costs.
S-19255 Series delivers clean power supply with little noise, which is ideal for automotive cameras and transmission RF circuits.

Use of Small I/O Capacitors further minimizes overall footprints
S-19255 Series permits use of 0.1μF input capacitors and 1.0μF output capacitors.
Small and readily available capacitors can be used instead of large capacitors to easily minimize the overall footprints.
