CSR/CSRN chip resistors for cost effective current sensing
Sense resistors are commonly used in applications such as low-power electronics, consumer devices, lighting systems, and security or detection equipment for power monitoring and control.
These applications often do not require ultra-low resistance values, tight precision tolerances, or low temperature coefficient of resistance (TCR). Instead, they prioritise flexibility in form factor and affordability.
Stackpole’s CSR/CSRN series of thick film current sense resistors are well-suited to these needs, offering a wide selection of sizes and resistance values at a competitive cost, enabled by robust thick film technology. The CSR/CSRN series is available with resistance values ranging from 3 milliohms to 7.5 ohms, depending on the size, and offers tolerances as low as 1%.
Package sizes range from 0201 (rated at 0.05W) to 1225 with long-sided terminations and a power rating of up to 3W. This extensive range of sizes and values makes the CSR/CSRN series an excellent choice for prototyping and rapid product development.
Pricing for the CSR/CSRN varies with size, value, and tolerance. Contact Stackpole for volume pricing. Many popular sizes and resistance values are in stock through Stackpole directly or through distribution partners.
