TSM32-H25CQ33ST-33.330M

Oscillators Overview

The TSM32-H25CQ33ST-33.330M is an ultra-miniature surface-mount HCMOS crystal oscillator manufactured by Transko Electronics, Inc. It operates at a nominal frequency of 33.330 MHz with a supply voltage of 3.3V and maximum supply current of 30mA. The device features ±25ppm frequency stability and functions within an operating temperature range of -40°C to 85°C. It utilizes a 4-SMD, no-lead package measuring 3.20mm x 2.50mm x 1.20mm.

Oscillators Feature Summary

• Ultra-miniature SMD package design for space-constrained applications
• HCMOS output signal generation
• Enable/Disable functionality support

Oscillators Applications

• Portable wireless devices
• Mobile test equipment
• Beacons and rescue systems

Oscillators Procurement Notes

Verify the specific suffix codes against official Transko documentation to ensure accurate frequency, voltage, and package specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Cross-reference pinout diagrams with target PCB layout to prevent interface mismatches during assembly.

Oscillators Selection Notes

Select this component when a compact form factor is required alongside standard HCMOS logic compatibility. Ensure the thermal environment remains within the specified -40°C to 85°C operational range. Validate that the 3.3V supply rail can sustain the maximum 30mA current draw without significant voltage droop under load conditions.

Oscillators Part Context

This part belongs to the TSM32 series of ultra-miniature oscillators from Transko Electronics. The series incorporates MEMS technology and offers various SMD packages ranging from 2.0x1.6mm to 7.0x5.0mm. These devices are designed as drop-in replacements for discontinued ceramic filter models such as Murata SFSCE or Epson VG-1201CA variants.

Oscillators Replacement Considerations

Transko recommends the TMM series or OX-P series OCXOs as potential alternatives depending on performance needs. For discontinued Epson VG-1201CA models, the TSMV series is cited as a fit-form-function replacement.
