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.
