Advance Data Sheet: FReta iEB Series
EMC Considerations: TDK Innoveta power modules are designed for use in a wide variety of systems and applications. For assistance with designing for EMC compliance, please contact TDK Innoveta technical support.
Input Impedance:
The source impedance of the power feeding the DC/DC converter module will interact with the DC/DC converter. To minimize the interaction, a
Reliability:
The power modules are designed using TDK Innoveta’s stringent design guidelines for component derating, product qualification, and design reviews. Early failures are screened out by both
Input/Output Ripple and Noise Measurements:
automated final test. The MTBF is calculated to be greater than 3.9M hours at full output power and Ta = 40˚C using the Telcordia
Improper handling or cleaning processes can adversely affect the appearance, testability, and reliability of the power modules. Contact TDK Innoveta technical support for guidance regarding proper handling, cleaning, and soldering of TDK Innoveta’s power modules.
Quality:
TDK Innoveta’s product development process incorporates advanced quality planning tools such as FMEA and Cpk analysis to ensure designs are robust and reliable. All products are assembled at ISO certified assembly plants.

The input reflected ripple is measured with a current probe and oscilloscope. The ripple current is the current through the 12uH inductor.
The output ripple measurement is made approximately 9 cm (3.5 in.) from the power module using an oscilloscope and BNC socket. The capacitor Cext is located about 5 cm (2 in.) from the power module; its value varies from code to code and is found on the electrical data page for the power module of interest under the ripple & noise voltage specification in the Notes & Conditions column.
