Details from the label:
Type: CBB61
Capacitance: 1.8 µF ±5%
Voltage: 450 VAC
Frequency: 50/60 Hz
Max temp: +70 °C
Use: AC motor / fan run capacitor
Key difference vs the others you showed:
Earlier: 1.2 µF / 1.25 µF
This one: 1.8 µF → much higher
What that means in real life:
Do NOT replace a 1.2–1.25 µF capacitor with 1.8 µF unless the motor specifically calls for it.
A higher µF can cause:
Higher motor current
Extra heating
Noisy operation
Reduced motor life
Rule of thumb for fans:
Always match the µF value as closely as possible
Voltage rating can be equal or higher (450 VAC is good)
Typical ceiling fan values:
Small fans: 1–1.5 µF
Standard ceiling fans: 2–3 µF (often split across speed settings)
