Cases such as 1206, 0805, 0603, 2835, 5630 are used as a standard electronic component case and these cases can be used for many different electronic components. These cases are also called SMD (Surface Mount Device) and these cases can be surface mounted on electronic devices.

SMD Leds are the leds in these cases and these leds are generally used to save power. SMD Leds are available in various colors and these colors have different properties. For example, white SMD LEDs are generally used for lighting and red SMD LEDs are generally used to give warning signs.

Bottom LEDs are the LEDs in the bottom covers and these LEDs are generally used for lighting purposes. Dip Leds are available in various colors and these colors have different properties. For example, white Dip Leds are generally used for lighting and red Dip Leds are generally used to give warning signals.

Dimensions such as 3mm, 5mm and 10mm show the dimensions of the Dip Leds. These dimensions affect the visibility of the Dip Leds and therefore different dimensions are used for different purposes. For example, 3mm Dip Leds are generally used in small devices and 5mm Dip Leds are generally used in medium sized devices. 10mm Dip Leds are generally used in large devices and these leds give more light.
