Comparison of CBB film capacitors and chip capacitors

Nowadays, the number of mobile phones supporting wireless charging is increasing, and most mobile phone manufacturers do not give wireless chargers, which leads to a large demand for wireless chargers. At present, when manufacturing wireless chargers, the price of NPO chip capacitors is high. It is more expensive, the cost is very high, and the CBB film capacitor is relatively cheap. Which one is better? The comparison between the wireless charging chip capacitor and the CBB film capacitor helps everyone choose scientifically.

1. Wireless charging chip capacitor.

The wireless charger usually uses a 104/NPO material capacitor in a 1206 package. The NPO capacitor has high stability and low loss compared to a low-cost MLCC capacitor. The wireless charger internally uses a very low loss NPO capacitor in series with the transmitter coil to match the transmitter coil, producing an alternating electromagnetic field that can be received. However, due to the increase in the unit price of the chip capacitors in the past two years, even if there is a fall in the current situation, there is still a problem of high cost when using chip capacitors.

2. CBB film capacitor:

Polypropylene capacitors, CBB fall into this category. The main isomorphism of the film capacitor is as follows: no polarity, high insulation resistance, excellent frequency characteristics (wide frequency response), and low dielectric loss. The main advantages of Zhixu CBB film capacitors: the unit price is obviously cheaper than the chip capacitor, and the unit price advantage is obvious.

I believe that through the above comparison, everyone has an answer to CBB capacitors and chip capacitors, no matter which one you choose, pay attention to quality!
