- Mean Time Between Failure (MTBF)
- Unit of measure, expressed in hours, that gives the relative reliability of a converter. MTBF data is based upon actual operating data (demonstrated) or derived per the conditions of MILHDBK-217F (calculated).
- EMI Filter
- Filter placed at the input to a converter that minimizes the effect of EMI on the converter and the associated system.
- Ratio of total output to input power expressed as a percentage. Efficiency is normally measured at full rated output power and nominal input line conditions.
- Electromagnetic Interference (EMI)
- Noise generated by a converter (typically by the noise generators action of the adaptor.) Usually specified as meeting agency limits for conducted EMI (noise reflected back at the power bus) or radiated EMI (noise emitted into the area surrounding a converter).
- Electrostatic Discharge (ESD)
- Current produced by two objects having a static charge when they are brought close enough to produce an arc or discharge.
- Electrostatic Shield
- See Faraday Shield
- Case or container used to package in small plastic or metal cases that protect the internal components from the outside environment and also improve thermal and noise performance.
- Equivalent Series Inductance(ESL)
- Inductance in series with an “ideal” capacitor. Sources include leads, terminals, electrodes etc.
- Equivalent Series Resistance (ESR)
- Resistance in series with an :ideal” capacitor. Sources include lead resistance, terminal losses, etc. An important specification for high frequency applications
