The yellow is the chip capacitor.
update
ceramic capacitor (ceramic capacitor) is a capacitor made of ceramic material as a medium, coated with a metal film on the surface of the ceramic, and then sintered at high temperature as an electrode. It is usually used in highly stable oscillation circuits as loop, bypass capacitor and cushion capacitor.
Ceramic capacitors are divided into high-frequency porcelain and low-frequency porcelain. A capacitor with a small positive capacitance temperature coefficient used in highly stable oscillation circuits as a loop capacitor and as a cushion capacitor. Low-frequency ceramic dielectric vessels are limited to bypass or DC isolation in circuits with low operating frequencies, or where stability and loss requirements are not high (including high frequencies). Such capacitors should not be used in pulse circuits because they are easily broken down by pulse voltages.
