CIRCUIT BOARD LAYOUT NOTES
Type SR Current Sense Resistors utilize Caddock's Micronox® resistance
The special performance features of these Type SR Current Sense
• Available in Standard Resistances down to 5 milliohm.
• Non-Inductive Design.
• Terminals are constructed for Kelvin connections to the circuit board.
• Compact footprint.
Measurement note: For purposes of these specifications, resistance measurement shall
be made using Kelvin connections (four wire) with appropriate current and sense con-
nections to the device terminals.
C = Current connection
Circuit Board Layout: The circuit board traces connecting to the current terminals must
be sized appropriately for the current flowing through the trace. For example; 0.005Ω
operated at 2.0 Watts would have 20 amps flowing through the circuit board traces into
the current terminals.
