When designing AC-powered systems, selecting the right capacitor ensures efficiency, durability, and consistent performance. In this article, we’ll explore the differences between jb’s CBB60, CBB61, and MPP capacitors—and how each fits specific AC applications.
CBB60, CBB61, and MPP: What's the Difference?
All three types are designed for AC operation, but with distinct strengths. Here's a quick comparison:
| Model | Application | Case Type | Capacitance | Voltage |
|---|---|---|---|---|
| CBB60 | Motor run (pumps, washing machines) | Round plastic | 1–100μF | 250/450VAC |
| CBB61 | Fan motors, compact appliances | Square plastic | 1–20μF | 250/450VAC |
| MPP | AC filtering, PFC circuits | Film (metallized polypropylene) | Customizable | 250–630VAC |
Key Application Scenarios
CBB60 Round AC Motor Run Capacitors: Ideal for heavy-duty single-phase AC motors, water pumps, washing machines, compressors, and high-torque industrial machinery.
CBB61 Square Fan Capacitors: Specially designed for space-constrained HVAC units, ceiling fans, ventilation systems, exhaust fans, and home appliances.
MPP Metallized Polypropylene Film Capacitors: Built for power electronics, AC line filtering, LED lighting ballasts, power factor correction (PFC), and high-frequency inverter circuits.
