Product details

The 4-SMD, no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint for space-constrained PCBs.

This suits battery-powered or intermittent-operation designs where the oscillator must not load the rail during sleep — the 6.3 mA max active current is typical for a 25 MHz CMOS output at 3.3V.

Despite the AEC-Q100 rating, this part is not specified for -40°C operation; it belongs in indoor, office, or appliance environments, not under-hood or outdoor exposed locations.

Frequently asked questions

Does DSC1001DC2-025.0000 have AEC-Q100 qualification?

Yes, the DSC1001DC2-025.0000 is rated AEC-Q100, meaning it has passed automotive-grade IC reliability stress tests.

What is the standby power-down function on the DSC1001?

The standby (power-down) function disables the output and drops current consumption to 15 µA max, allowing the oscillator to be gated off during system sleep without draining the battery.

Can I replace a quartz oscillator with this MEMS oscillator DSC1001DC2-025.0000?

Yes, the DSC1001DC2-025.0000 is a drop-in MEMS replacement for a 25 MHz quartz oscillator in the same 4-SMD no-lead footprint. The MEMS resonator offers better shock and vibration tolerance than quartz, though the temperature stability (±25 ppm) is comparable to a standard quartz XO.

Is the DSC1001DC2-025.0000 suitable for automotive applications?

It carries an AEC-Q100 rating, but its 0°C to 70°C temperature range means it is not suitable for under-hood or exterior automotive use. It can be used in cabin electronics where the ambient stays within that commercial range.
