Kt Kingtronics Difference Between Melf and SMA Package
23 Nov 2016Do you know what’s the difference between Melf and SMA Package? Let us take a comparison, you can easy to get features of them. Please refer to the below table.
| Comparison between Melf and SMA package | |
| Build in massive copper plugs | Build in copper leadframe technology |
| Superior thermal resistance due to massive plugs removing heat easily | Leadframe technology possess higher thermal resistance |
| Superior surge current rating due to high heated capacity of plugs, absorbing easily short lasting high energy surges | Leadframe technology has got less heat capacity |
| Tends to “roll away” during assembly, therefore better fitted for wave soldering | Applicable to all kinds of welding such as reflow or wave soldering |
| More sensitive against mechanical forces applied to the plugs | Leadframe technology provides better stress relief, therefore less sensitivity against mechanical stress to the leads |
| Parameters of a 1A/1000V | Parameters of 1A/1000V |

About
Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
