Capacitance: 45 µF (±5%)
Voltage: 450V AC
Frequency: 50/60 Hz
Protection: SH (Self-healing)
Standard: EN60252-1
Terminals: 2-pin
Brand marking: SHENGE (same family as the 40 µF one)
Compressor run capacitor
High-load outdoor AC units
Common in 2.0 – 3.0 HP systems (brand/design dependent)
µF must match exactly → 45 µF
Voltage 450V or higher only
Must be run capacitor (CBB65), oil-filled metal can
Do NOT replace with 40 µF or 50 µF unless manufacturer allows
12.5 µF → small fan motor
16 µF → medium motor
20 µF → mid compressor
30 µF → larger compressor
40 µF → heavy compressor
45 µF → very heavy compressor load
