KOA Speer Electronics, Inc. Chip Resistor - Surface Mount RN732ATTD1240F10

The RN732ATTD1240F10 is a surface mount chip resistor from Lingto Electronic Limited, featuring a nominal resistance of 124 ohms with a tolerance of ±1%. It is designed for applications requiring a power rating of 1/10W (0.1W) at an ambient temperature of 70°C. The resistor utilizes a nickel chromium thin film element and is compliant with EU RoHS requirements, making it suitable for lead-free applications. This component is packaged in the 0805 size format, which measures approximately 2.0mm x 1.25mm. The resistor operates effectively within a temperature range of -55°C to +155°C, with a maximum overload voltage of 50V. The temperature coefficient of resistance (TCR) is specified at ±100 ppm/°C, ensuring stable performance across varying temperatures. Engineers should note that the product is marked as end-of-life, with the last time to buy indicated as September 30, 2022, and a recommended replacement part is the RN73R series. This information is crucial for long-term project planning and component sourcing.
