Welwyn Components, Ltd. Current Sense Res, 0R05, 1%, 125 Mw; Resistance Tt Electronics/welwyn LRCS0805-0R05FT5

The Current Sense Resistor, part number 12AC1344, is a low-value surface mount chip resistor designed for current sensing applications in power electronic systems. It has a resistance value of 0.05 ohms with a tolerance of ¬±1%. The resistor is rated for a power dissipation of 125 mW at 70¬8C and is compliant with RoHS standards, ensuring it is free from lead and other hazardous substances. This resistor features a temperature coefficient of resistance (TCR) of ¬±400 ppm/¬8C, which indicates its stability over temperature variations. It is constructed on an alumina substrate, providing durability and resistance to industrial solvents. The device is available in an 0805 case style, measuring 2.0 mm x 1.25 mm, and is packaged on 8 mm wide paper tape for easy handling and placement in automated assembly processes. The resistor can withstand a maximum isolation voltage of 200V and has a wide operating temperature range from -55¬8C to +155¬8C. It is suitable for applications requiring precise current measurement and is designed to perform reliably under various environmental conditions.
