Through-hole components and surface mount components differ significantly in structure, process, and application. Surface mount components are suitable for compact consumer electronics, while through-hole components are used in high-power industrial equipment.
The core components supplier information of Xiaomi Pengcheng N90, released in late July, has been gradually exposed, covering multiple modules such as powertrain systems, intelligent driving and cabin, vehicle wiring harnesses, chassis control, and low-voltage distribution.
Specializing in passive component procurement, Huanian Mall provides direct factory supply, on-site fast shipping, and technical selection support.
Analyzing the internal structures of capacitors, resistors, inductors, and other components to reveal their performance principles and application values.
The June component market showed a K-shaped divergence, with a surge in AI and automotive demand, leading to widespread price increases in passive components and memory chips, and accelerated domestic substitution.
In basic components such as resistors, inductors, capacitors, and diodes, distinguishing polarity is a fundamental practical point in circuit welding, assembly, and debugging. It is also the most error-prone and fault-prone part, with significant differences in polarity characteristics among resistors, capacitors, and inductors.
A quick reference table for SMD capacitors, inductors, ferrite beads, and diodes, helping with circuit design selection.
Global market data on passive components from 2020 to 2025 clearly shows that the industry maintained steady growth for five consecutive years, with a compound annual growth rate (CAGR) of 8.1%, confirming its long-term expansion trend. At present, technological innovation is accelerating rapidly. Miniaturization, high frequency and high power, automotive-grade high reliability, and integrated modularization have become the four major threads of product iteration. A large number of domestic manufacturers are speeding up to achieve leapfrog progress in both technology and market share.
Market data shows that the global market size of integrated molded inductors reached USD 4.755 billion in 2025. Industry estimates project the market volume will expand to USD 9.327 billion by 2032, with a steady compound annual growth rate (CAGR) of 10.13% over this period.
At the Shanghai International Symposium on Circuits and Systems held on May 25, He Tingbo, President of Huawei's Semiconductor Business Group, officially unveiled the Tao (τ) Law, a new principle guiding the development of the semiconductor industry, alongside a supporting academic paper.
