Additional Details:

The 'WR02' indicates the case size of the resistor, typically referring to its physical dimensions (e.g., 0402, 0603, 0805). 'X102' indicates the resistance value. In this case, '102' translates to 10 x 10^2 ohms, or 1 kΩ (kiloohm). The 'JAL' likely refers to the tolerance code, indicating the precision of the resistance value (e.g., J=5%, F=1%). The specific power rating of the resistor depends on its case size and material composition, and it determines the maximum power the resistor can dissipate without overheating. Consult the manufacturer's datasheet for detailed specifications, including resistance value, tolerance, power rating, temperature coefficient, and recommended soldering conditions.
