MELF-ADAPTER MELF ADAPTER BOARD


MELF adapter board.
The 4 wires Kelvin connectionis usefull in aplications using resistors for current sampling: 2 connections for injecting current and 2 for measuring voltage.
MELF-SIL
PCB type: FR4 plated through
PCB dimensions: 11 x 8,3 x 1,5 mm
For SIL connectors (not included) with pitch: 2,54 mm
Bottom copper as ground plane / heatsink: yes
Solder mask isolation layer: yes
Copper Surface: gold plated
ROHS compliant
The bottom copper layer is available as ground to minimize noise and work as a small heatsink for power resistors
