Large capacity, small size, can store enough energy smooth output rectifier voltage;
Lower part of dc ac component, restrain the output ripple;
Miniaturization of the charger.
Large ripple, low ESR absorption of ripple produced from rectifier circuit;
EMI interference suppression;
Lower the temperature in the condenser.
High pressure, resistance to lightning withstand impact from the input voltage of the rectifier circuit;
Long life, high reliability work under high temperature, and satisfies the requirement of product design life.
36 years ShenMao electronic subsoil aluminum electrolytic capacitor
industry, for the power supply quick charge series has the rich production experience and some application examples.
Today, we share a story about VIVO 33 w Flash at 2.
0 and dismantling of quick charge report.
一、体内33 w FlashCharge 2。
0 fast electrical appearance vivo 33 w FlashCharge 2.
0 fast was flat in shape, shell part adopts is white PC flame retardant materials, with a fixed pin and USB
On the back of the charger with product parameters, vivo FlashCharge2.
Model: V3330L0A0 -
240V~ 50/60Hz 0.
85 a,出口:5 v / 2 a或9 v / 2 a或11 v / 3 a。
Volume compared with 30 w apple PD fast was electric, vivo the charger's body appear more slender.
Using ChargerLAB POWER -
0 quick charge, the QC2.
二,体内33 w FlashCharge 2。
0 fast was the ultrasonic welding appliances dismantling charger shell, very strong, strong output, pry after deformation was able to open the side cover.
After take off cover plate, you can see the internal PCB fixed guide groove, the inside of the shell output USB -
Shell inside use metal shrapnel and PCBA module contact conduction mode.
PCBA module and PCB are angled look yellow, single-sided circuit board, the main for the plug-in components, including transformer, capacitor, time delay fuse, safety capacitance X, common mode inductor, etc. , and then use glue injection reinforcement between components.
Around the transformer and electrolytic capacitor
using a large number of fixed and thermal conductivity silica gel.
Time delay fuse, 250 v 2 a.
Use white mara tape winding transformer and printing the label information.
Beside the transformer is equipped with a PWM power supply capacitor, chip by Koshin ShenMao electronics offers, 50 v 4.
a介面讯设计,定制介面,招聘塑胶自然防尘,左侧为两颗y电容,右侧为两颗固语态滤波电容,由申茂电子提供的固语态电容ks / 16 v 470μf,尺寸5。
