The HH15N1R5B500LT is part of the Walsin high-current surface-mount chip resistor series. It is a 1 ohm, 5 watt device designed for use in high-current power control applications. The device has a chip size of 15mm × 5mm, and is housed in a lead-free, IR-reflow compatible, industry-standard, Thermal Stability 4 terminal, high-temperature ceramic package. This component is excellent for applications requiring a large amount of power control in a very limited space.
