KOA Speer Electronics, Inc. Chip Resistor - Surface Mount RN73H1ETTP1212B50

The RN73H1ETTP1212B50 is a surface mount chip resistor from Lingto Electronic Limited, designed for high reliability applications, particularly in automotive environments. It features a resistance value of 12.1 kOc with a tolerance of ¬±0.1%, and a power rating of 0.063W at an ambient temperature of 85¬8C. The resistor operates effectively within a temperature range of -55¬8C to +155¬8C, ensuring stability under varying conditions. This component is constructed with a thin metal film, providing low current noise and high precision, with a temperature coefficient of resistance (TCR) of ¬±25 ppm/¬8C. It is also AEC-Q200 tested, indicating compliance with automotive standards for reliability. The RN73H series is noted for its improved moisture resistance due to a glass passivation layer and verified sulfur resistance according to ASTM B 809-95. Engineers considering this resistor for their projects can expect long-term stability, with minimal resistance change over time, making it suitable for critical applications where precision is essential.
