Susumu KRL Series Precision Current Sensing Resistors - EXPANSION

NEW! Now available with large resistive elements that evenly distribute heat.

Susumu KRL Series Precision Current Sensing Resistors extend the resistance range from the existing RL / PRL series down to 1mΩ. The KRL series has improved TCR that is as low as ±50 ppm/ºC and is available in two geometries - longer side and shorter side terminal type - ranging from 1/3W to 5W power rating. Also available are types for high temperature applications (up to 170ºC) and for low thermal emf applications. The Susumu KRL Series Precision Current Sensing Resistors offer a face down mounting for accurate sensing. RoHS compliant, the protective coating is halogen-free.

Chip Resistors

Susumu offers a wide range of thin film chip resistors, including its core product, the RG series. The RG series are precise and reliable thin film chip resistors. Susumu also offers excellent current sensing chip resistors, such as the KRL series.

KRL Precision Current Sensing Resistors

Susumu KRL Precision Current Sensing Resistors include large resistive elements that evenly distribute heat. These short-side terminal, low-resistance chip resistors are available in two types: high temperature (operating temperature up to 175°C) and low emf type (operating temperature up to 155°C). The KRL series has been officially listed by NASA under its NASA Electronic Parts and Packaging (NEPP) program as an Industry Leading Parts Manufacturer (ILPM) and recognized as an Established COTS part. This recognition follows the earlier qualification of our RG series, marking another milestone in our contribution to space-grade component reliability. The facedown construction offers a choice between bottom-only or wrap-around terminal. The devices feature high current handling capability and a wide range of power ratings. Susumu KRL Precision Current Sensing Resistors are ideal for automotive electronics, AC/DC converters, DC/DC converters, motors, inverters, and office automation equipment.
