Technical Specifications:

The PFC-W0805LF-03-59R0-B resistor has a resistance value of 59.0 Ω (59R0 indicates 59.0 ohms). The 'B' signifies a tolerance of ±0.1%. The '03' likely refers to the power rating, commonly 0.125W for 0805 size resistors. Thin film resistors typically exhibit a low TCR, generally around ±25 ppm/°C. The typical operating temperature range spans from -55°C to +155°C. The resistor is usually constructed with a ceramic substrate and a thin film resistive element. The terminations generally involve a nickel barrier with tin plating for reliable solderability.
