If you are producing a variety of PCBs (Printed Circuit Boards), the ability of the board to dissipate heat is critical. Effective heat dissipation prevents PCBs from overheating, causing performance problems or catastrophic failures.

In terms of price, common capacitors are less expensive, about 2-5 RMB, while electrolytic capacitors are relatively more expensive, the price may be below 20 RMB. The exact price will be affected by the brand, capacity, withstand voltage and other factors.

AC capacitors are essential components in electronic and electrical systems, used for energy storage, voltage regulation, and improving motor efficiency. This article explains how AC capacitors work, common types (such as start capacitors and run capacitors), and their key applications in household appliances and industrial equipment. It also provides buying tips to help you select the best product based on voltage, capacitance, and durability, ensuring stable operation and energy savings.
A load resistor is a resistive element in a circuit that is used to consume electrical energy or simulate an actual load and is mainly used to simulate or replace an actual load in order to test or adjust the performance of a circuit.

A variable resistor is an electronic component whose resistance value can be adjusted manually or automatically to control the current or voltage in a circuit. It is widely used in electronic circuits to adjust parameters such as volume, brightness, and temperature.
Resistors are essential passive components that limit current flow and divide voltages in electronic circuits. Governed by Ohm’s Law (V=IR), their resistance (R) determines how they control energy as heat (P=I²R). From fixed resistors to variable types like potentiometers, they enable precise circuit tuning, signal attenuation, and protection against overcurrent. Key applications include voltage dividers, LED current regulation, sensor interfacing, and analog signal processing. This guide covers resistor principles, critical calculations, and their role in modern electronics—ensuring stable, efficient circuit operation.

Capacitors are fundamental components in electronics, storing energy as electric field energy between charged plates. Their stored energy can be calculated using three key formulas—E=½CU², E=½QU, and E=Q²/2C—depending on known parameters like capacitance (C), voltage (U), or charge (Q). Factors such as plate area, spacing, and dielectric material influence their storage capacity, while supercapacitors push limits with rapid charge/discharge cycles. Widely used in power systems, renewable energy storage, and electronic circuits, capacitors play a crucial role in stabilizing voltage, filtering signals, and recovering energy. This guide explores capacitor energy principles, critical calculations, and modern applications.
Resistors (commonly referred to simply as "resistors" in daily usage) are current-limiting components. When connected in a circuit, a resistor typically has a fixed resistance value with two pins that restrict the current flow in its connected branch.

The cost of a PCB board is calculated in the following way: At the time of initial fabrication, there is a one-time photographic fee, which includes printing on the front and back, and one photo for each side.

Selecting the right PCBA supplier requires evaluating technical capabilities (SMT/DIP), quality control, certifications, supply chain management, and cost structure. This guide covers key selection criteria, industry-specific requirements, and risk mitigation strategies to ensure high-quality PCB assembly for prototypes or mass production.
