CBB60 Capacitor: Comparison with CBB61 and SPP5 Capacitors

Characteristics and Parameter Comparison of CBB61 and SPP5 Capacitors

Capacitors play a crucial role in electronic circuits, especially in AC motor applications, power filtering, and startup circuits. CBB60, CBB61, and SPP5 are three common types of metallized polypropylene film capacitors, each with distinct features and applications. This article focuses on the CBB60 capacitor while comparing its specifications with CBB61 and SPP5 capacitors.

1. CBB60 Capacitor

The CBB60 is a metallized polypropylene film capacitor primarily used for starting and running single-phase AC motors, such as those in washing machines, air conditioners, and water pumps. It offers high voltage resistance, low loss, and excellent stability.

Key Parameters

Applications
Single-phase motor startup and operation
Pumps, fans, compressors
Household appliances (e.g., washing machines, air conditioners)

2. CBB61 Capacitor

The CBB61 is another metallized polypropylene film capacitor, but it is mainly used for high-frequency filtering and electromagnetic interference (EMI) suppression, commonly found in electric fans, lighting devices, and low-power appliances.

Parameter Comparison (vs. CBB60)

Applications
Electric fan speed control
LED driver circuits
EMI suppression in small appliances

3. SPP5 Capacitor

The SPP5 is a metallized polypropylene film capacitor designed for high-pulse and high-stability applications, such as electronic ballasts and switching power supplies.

Parameter Comparison (vs. CBB60 & CBB61)

Applications
Electronic ballasts
Switching power supplies
High-frequency inverter circuits

How to Choose the Right Capacitor?
Motor startup and operation → CBB60 (high capacitance, high voltage rating)
Fan speed control & EMI filtering → CBB61 (low capacitance, high-frequency suitability)
Pulse circuits & switching power supplies → SPP5 (high voltage endurance, pulse resistance)
