Technical Specifications:

The PFC-W0603R-03-2492-B-3085 resistor has a resistance value of 24.9 kΩ (2492 indicates 249 with a multiplier of 10^2). The 'B' signifies a tolerance of ±0.1%. The '03' most likely represents a 0.1W power rating, typical for 0603 size resistors. The resistor's TCR (Temperature Coefficient of Resistance) is typically very low for thin film resistors, frequently in the range of ±25 ppm/°C. The typical operating temperature range is -55°C to +155°C. The construction involves a ceramic substrate with a thin film resistive layer and standard terminations, often a nickel barrier with tin plating for optimal solderability.
