Product details

The DSC1001BI2-026.9730T: Its AEC-Q100 qualification makes it suitable for automotive electronics, including engine control units, infotainment, and ADAS modules where reliability under thermal and mechanical stress is mandatory. The MEMS resonator base provides inherent shock and vibration resistance compared to quartz-based oscillators, reducing failure risk in high-vibration environments like factory floors or vehicle powertrains.

Standby mode and power budget for battery-backed designs

A standby (power-down) function on pin 1 drops the supply current to 15 µA max when disabled, while active operation draws 6.3 mA max – a 400× reduction that matters for always-on systems like automotive body controllers or IoT sensors that sleep between wake events. The wide supply range of 1.8V to 3.3V allows the oscillator to share a rail with a 1.8V MCU core or a 3.3V peripheral bus without an extra regulator, simplifying the power tree.

Housed in a 5.0 mm × 3.2 mm 4-SMD no-lead package (0.90 mm seated height), the DSC1001BI2-026.9730T fits standard oscillator footprints and is supplied on tape and reel for automated assembly.

Frequently asked questions

Is DSC1001BI2-026.9730T AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating, making it qualified for automotive-grade applications.

Does DSC1001BI2 have a standby mode?

Yes, it includes a standby (power-down) function that reduces supply current to 15 µA max when disabled.

What is the difference between DSC1001BI2 and DSC1001DI2?

The suffix indicates different frequency stability or temperature range options within the DSC1001 family; the BI2 variant offers ±25 ppm stability over -40°C to +85°C, while DI2 typically targets a wider temperature or tighter stability grade. Confirm the specific DI2 datasheet for exact ratings.
