Technical Specifications:

The PFC-W0805LF-03-9092-B has a resistance value of 90.9 kΩ (9092 indicates 909 with a multiplier of 10^2). The 'B' signifies a tolerance of ±0.1%. The '03' likely refers to the power rating, typically 0.125W for 0805 size resistors. Thin film resistors commonly have a low TCR, usually around ±25 ppm/°C. The operating temperature range is usually from -55°C to +155°C. The resistor is typically constructed with a ceramic substrate and a thin film resistive element. The terminations typically consist of a nickel barrier with tin plating for improved solderability and prevention of tin whisker growth.
