High overload capability and a wide operating-temperature range marks the Bourns PWR4413 Series of through-hole current-sense resistors. The resistors feature 0.8-mm and 1.00-mm terminations and are capable of up to 30 A of continuous current and pulses up to 78 A. These current-sense resistors are designed for applications that require tighter precision and higher operating temperatures and can be utilized as a drop-in replacement for other, less durable types of resistors. The devices feature low inductance, are RoHS-compliant, and offer excellent protection characteristics suitable for a broad range of products including industrial, automotive and medical applications. Key specifications include power ratings at 85°C of 1 W, 3 W, and 5 W; a resistance range of 0.01 to 0.1 ?; and an operating-temperature range of -55° to +325°C. The resistors can handle five times their rated power capacity for up to 5 seconds. The PWR4413 Series current-sense resistors are priced from $0.70 in 50-piece quantities and are available now.
