Procurement Notes
Verify the exact part number VTX-101-1614 against manufacturer datasheets to confirm the 1:4 ratio and 600/10k impedance specifications. Ensure compatibility with PCB footprint requirements and operating temperature ranges. Confirm RoHS compliance status if required by project standards. Cross-reference supplier documentation for accurate lead times and packaging details before ordering.
Selection Notes
Select this component when a 1:4 step-up ratio is required for audio impedance transformation between 600 and 10,000 ohms. Consider the 1500 Vac isolation rating for safety-critical audio interfaces. Evaluate the 60 Hz to 25 kHz bandwidth against the specific audio application needs. The encapsulated form factor suits automated PCB assembly processes requiring robust mechanical fixation.
Part Context
This transformer belongs to the Vigortronix VTX-101 miniature audio range. The series emphasizes low distortion and high-quality encapsulation for reliable PCB integration. Similar models in the family offer various winding ratios and impedance configurations while maintaining consistent mounting styles and isolation characteristics for standardized audio circuit designs.
Replacement Considerations
Direct substitutes must match the 1:4 ratio, 600/10k impedance, and encapsulated PCB mount style. Verify equivalent frequency response and isolation voltage ratings. Consult manufacturer cross-reference lists for approved alternatives ensuring identical pinout and physical dimensions to maintain PCB layout integrity.
