The DSC1033BC1-026.0000T is a MEMS-based XO (standard oscillator) from Microchip's PureSilicon™ series, delivering a 26 MHz CMOS output from a 3.3V supply rail. Housed in a 5.00mm x 3.20mm 4-SMD no-lead package, it targets commercial-temperature (0°C~70°C) indoor equipment where a quartz crystal's mechanical resonance is replaced by a silicon MEMS resonator.
Microchip lists the DSC1033BC1-026.0000T as Obsolete.
The 3 mA typical supply current (3mA max) keeps the thermal footprint low in a sealed enclosure.
