Product details

AEC-Q100 qualification means this oscillator has passed automotive-grade reliability stress tests — it is suited for under-hood or cabin electronics where vibration and thermal cycling are routine. The 4-SMD, No Lead package (5.00mm x 3.20mm) is a common footprint shared with many quartz oscillators, making it a drop-in replacement candidate on existing PCB layouts.

Standby power-down and supply flexibility

A dedicated Standby (Power Down) function pulls the output to high-impedance and drops supply current to 15 µA max — useful for battery-powered nodes that sleep between transmissions. The supply voltage range spans 1.8V to 3.3V, so the same BOM line can serve a 1.8V-core MCU or a 3.3V peripheral bus without a separate voltage translator.

Sourced through independent distribution; quoted to order against the BOM quantity.

Frequently asked questions

Is DSC1001BI2-040.0000 AEC-Q100 qualified?

Yes, the DSC1001BI2-040.0000 carries AEC-Q100 rating, which certifies it for automotive-grade temperature, reliability, and PPAP requirements.

Does DSC1001BI2-040.0000 have a standby feature?

Yes, the device includes a Standby (Power Down) function. When enabled, the output goes high-impedance and supply current drops to 15 µA max.

How does DSC1001BI2-040.0000 compare to a quartz oscillator?

The DSC1001 uses a MEMS resonator instead of a quartz crystal. The MEMS construction offers better shock and vibration tolerance, faster start-up, and a wider supply voltage range (1.8V to 3.3V) compared to many quartz oscillators that are tied to a single supply. The package footprint is the same 5.00mm x 3.20mm 4-SMD no-lead, so it can be a pin-to-pin swap on existing boards.
