MIH302548AH-27.000MHZ-T

Oscillators Overview

The MIH302548AH-27.000MHZ-T is a ceramic surface-mount oscillator from the MIH Series, manufactured by MMD (Abracon). It operates at a nominal frequency of 27 MHz with HCMOS output logic. The device supports multiple supply voltages including 5.0V, 3.3V, 2.5V, and 1.8V. Frequency stability ranges from ±10ppm to ±100ppm depending on the specific configuration. Operating temperature options include commercial (0°C to 70°C), extended (-40°C to 85°C), and industrial (-55°C to 125°C) grades. The package is a 5mm x 7mm ceramic SMD with four no-lead terminals.

Oscillators Procurement Notes

Verify the specific stability grade and temperature range suffixes when ordering, as these are determined by the part number structure. Confirm that the 27MHz frequency matches the system clock requirements. Ensure the selected supply voltage aligns with the target circuit design, as current consumption varies significantly between 5V and lower voltage options. Check for RoHS compliance status if required by project specifications.

Oscillators Selection Notes

Select this component based on the required frequency stability and operating environment. Higher stability grades (e.g., ±10ppm) may have different availability or lead times compared to standard grades. Consider the load drive capability; the device can drive up to 10 TTL gates or specific capacitance loads depending on the voltage. Verify the package dimensions (5mm x 7mm) fit the PCB layout constraints. Compare against the MI2025H48H series for similar form factors but different electrical characteristics.

Oscillators Part Context

This oscillator belongs to the MIH Series, which features a 5mm x 7mm ceramic SMD package. The series offers wide frequency ranges and multiple voltage options. MMD, now part of Abracon, provides these timing components for flexible global supply chains. The MIH series is designed for applications requiring hermetic sealing and robust performance in harsh environments.

Oscillators Replacement Considerations

Direct substitutes within the same series include other frequencies in the MIH302548AH line, such as MIH302548AH-25.000MHZ-T or MIH302548AH-20.000MHZ-T, provided the frequency difference is acceptable. Cross-series replacements like the MLHF502048AHP offer different package sizes and stability options but require mechanical and electrical re-verification.
