Product details

Why the full military temp range matters for your BOM

Microchip lists the DSC1121DM1-040.0000T as Active. This is a current-production part, so you can commit it to a new design without worrying about a forced redesign in the next 12–18 months.

AEC-Q100 and the 6-SMD no-lead package

AEC-Q100 qualification covers the temperature, reliability, and PPAP requirements for automotive-grade ICs. The 6-SMD no-lead package is a 2.50 mm × 2.00 mm footprint with a seated height of 0.90 mm.

Supply voltage range and enable/disable function

The part accepts a 2.25V to 3.6V supply, covering 2.5V and 3.3V rails without a separate regulator.

Frequently asked questions

Is the DSC1121DM1-040.0000T RoHS compliant?

The evidence does not list a RoHS compliance statement. Confirm with the datasheet or request a certificate of compliance at RFQ time.
