Bourns 1xxPC, SM8, SM10, SM/1xx and RTDW series

Bourns is pleased to announce the introduction of the Riedon™ precision wirewound resistors and precision wirewound temperature sensors by Bourns (RTDW Series). These releases enable designers to make precise current and temperature measurements for a range of applications.

The Riedon™ precision wirewound resistors by Bourns (1xxPC, SM8, SM10, SM/1xx Series) are designed with precision in mind. Offering Temperature Coefficient of Resistances (TCRs) of ±2PPM/°C and resistance tolerances as low as ±0.005 %, these resistors are designed for use in current sensing in applications such as smart energy metering, Battery Energy Storage Systems (BESS), and Battery Management Systems (BMS).

The Riedon™ precision wirewound temperature sensors by Bourns (RTDW Series) achieve accurate temperature sensing results by combining a tight resistance tolerance of ±1% and material selection allowing for TCRs as high as ±6000 PPM/°C. These sensors have a 0°C to +100°C temperature range for general use temperature sensing in applications such as Battery Energy Storage Systems (BESS) and industrial motor drives.
