EFT-U14R0M03A

Overview

The EFT-U14R0M03A is a piezoelectric transformer manufactured by Panasonic Electronic Components. It features a power rating of 4W and a voltage transformation ratio of 1:61. The component utilizes surface mount technology with physical dimensions of 35mm in length, 7.8mm in width, and 3.1mm in height. This specific part number is identified as containing lead and does not comply with RoHS environmental standards.

Feature Summary

• Piezoelectric energy conversion mechanism
• Surface mount package configuration
• High step-up voltage transformation capability

Applications

• Backlight power supplies for LCD panels
• High voltage generation circuits
• Electrostatic discharge protection modules

Procurement Notes

Verify RoHS compliance status prior to procurement as this specific variant contains lead and may be restricted in certain jurisdictions. Confirm the exact 1:61 transformation ratio matches the circuit design requirements. Ensure surface mount footprint compatibility with PCB layout specifications before finalizing orders.

Selection Notes

Select this component when a compact, high-ratio voltage step-up solution is required for backlight or HV applications. Consider the 4W power limit and lead content restrictions. Evaluate thermal management needs due to piezoelectric heating effects during operation.

Part Context

This part belongs to the EFT series of piezoelectric transformers from Panasonic. These components replace traditional magnetic transformers in specific high-voltage, low-power applications. The series offers size reduction benefits compared to equivalent magnetics.

Replacement Considerations

The EFT-U16R5M01A is a documented alternative within the same manufacturer line. Verify that its different electrical parameters suit the target application before substitution.
