CSx Current Sense Resistors

Stackpole Electronics CSx Current Sense Resistors are all lead- and halogen-free modules and include multiple series: CSRF, CSR, CSRN, CSNL, CSS, and CSSH. The CSRF series resistors feature current handling up to 26A, TCR down to ±50ppm/°C, and wide resistance range, and a high power rating of up to 5W. The CSR/CSRN resistors offer sizes ranging from 0201 to 1225 and power ratings up to 3W. The CSRN series includes sizes 0815, 2010, and 2512 with narrow terminations. The CSNL metal element current sensing resistors provide resistance ratings down to 1/2mΩ, a high-power design, and current handling up to 63A, and non-standard resistance values are available. The CSS/CSSH series includes standard and high-power (CSSH) options with a high-temperature performance of up to +225°C and AEC-Q200 qualification. Stackpole Electronics CSx Current Sense Resistors are REACH compliant and 100% RoHS compliant without exemption.
