The RS-05K433JT is a surface mount chip resistor made by the company Fenghua Advanced. It is an 0805 standard size resistor with a resistance of 43 kilo-ohms and a tolerance of ±5%. The power rating is 1/8 Watt. The resistor is RoHS compliant and is used mainly for electronic applications, typically for current limiting, voltage division, impedance matching, and filtering. The resistor is well suited for use in circuit boards, on modems, motherboards, and other circuits where space is limited and a smaller, more efficient resistor is needed.
