Vishay Intertechnology, Inc. Chip Resistor - Surface Mount WSR29L000FEA

The Metal Strip Resistor, part number 18X5150, features a resistance value of 0.009 Ohm with a tolerance of ¬±1%. It is designed for surface mount applications and is part of the WSR series, specifically in the 4527 package size. This resistor has a power rating of 2W and is suitable for current sensing, voltage division, and pulse applications, including use in switching and linear power supplies, instruments, and power amplifiers. The resistor is constructed with a solid metal nickel-chrome or manganese-copper alloy element, providing a low temperature coefficient of resistance (TCR) of less than 20 ppm/¬8C. It exhibits very low inductance, ranging from 0.5 nH to 5 nH, and has excellent frequency response up to 50 MHz. The operating temperature range is from -65¬8C to +275¬8C, and it is AEC-Q200 qualified, making it suitable for automotive applications. The resistor is also RoHS compliant, although lead-containing terminations are available. Engineers should consider this resistor for applications requiring precise low resistance values and high reliability under varying environmental conditions.
