0.47µF 100V Polyester Box Capacitor (Pack of 10)The polyester Box capacitor is made of two metal plates with the polyester film sandwiched between them, or the insulator might be covered with a metalized film. Polyester is the most widely utilised dielectric material in this capacitor, allowing the capacitor's construction to be simplified. These capacitors are pretty inexpensive and have excellent self healing properties. The dielectric & construction of polyester PET capacitors are used in

two literal comparators

DA (direction of motor A)

so if you're looking for an IC to provide optical isolation in your circuit design

The SMPS has high efficiency up to 86%

of Pins 10 Display Size 0

Its package is SOT-23

It uses ESP8266 Wi-Fi Board (SoC) for IoT Applications

completing the circuit

The XH JST series double-end female JST connector

TTP226 module has a capacitive touchpad detection design that can detect up to 8 touch keys

CH5 & CH6 Open to assignment for other functions FS-I6 Receiver Channel

So this IC basically has an IR (infrared) LED and a photo-transistor inside it
