1. product description: this product is specially developed and designed for resistance-capacitance buck circuit, which is used to replace the metallized film capacitor encapsulated by powder epoxy resin with traditional structure; The defects of traditional thin film capacitor are (easy to catch fire and burn; Short service life; The external dimensions are not standard; The wrap coat is easy to crack or explode);
Second, the MPP82-BOX resistor-capacitor special for step-down developed by JURCC is characterized by:

1. Traditional thin film capacitors have the risk of scalding when they are subjected to wave soldering (generally K-pin processing), and this product has no risk of scalding without K-pin (reducing cost);

2. The noise is smaller than that of traditional thin film capacitors;

3. Circuit boards with small size and suitable for high-density components;

4, the high frequency loss is small, can bear the impact of large AC peak surge voltage and current, and has strong overcurrent ability;

5. Special zinc-aluminum ratio;

6. Combining the detailed manufacturing process independently designed by JURCC and the dynamic RC capacitor capacity attenuation tester developed by JURCC;

7. Sampling control test of products: small capacity attenuation (long-term application of 250VAC,50HZ, capacity attenuation within 5% every year) and long service life;

8. Package with PBT synthetic resin material shell; And potting with flame retardant epoxy resin; The moisture-proof and flame-retardant capabilities are greatly improved; Good appearance consistency; Flame retardant grade b; Resistance to temperature 110℃!
Third, although this product is specially designed for resistance-capacitance buck; But it can also be used as the filter capacitor of power PFC;
Fourth, other uses: excellent frequency characteristics, small high-frequency loss, widely used in various electronic and electrical products bypass; Straightening; Filtering; Coupling; Resonance, etc!
