YAGEO RC0805FR-0718KL Chip Resistor Design and Materials

YAGEO’s RC0805FR-0718KL utilizes a high-grade ceramic substrate as its foundation. Metal electrodes are positioned at each end to facilitate solid contact with the thick film resistive element made from noble metal embedded in glass. To enhance long-term stability and resilience to external environmental factors, a secondary glass layer is applied over the resistive element. The resistor value is precisely set using laser trimming before a protective epoxy coat is applied. External terminations use matte tin over a nickel barrier, ensuring excellent solderability and long-term reliability.

Electrical Properties of YAGEO RC0805FR-0718KL Chip Resistor

The electrical performance of the RC0805FR-0718KL centers on its rated power and voltage capabilities. For this 1/8W (0.125W)-rated device, operation at up to 70°C is ideal, with derating required at higher ambient temperatures in line with standard resistor practice. The operating temperature range spans from -55°C to +155°C for RC0805 and similar sizes. When evaluating the device for your design, it’s crucial to ensure continuous working voltage does not exceed the calculated value, maintaining reliable circuit performance.
