Three important factors to consider when selecting SMD inductors

The main specifications of inductance include, in addition to size, the inductance value at switching frequency, DC impedance (DCR) of the coil, rated saturation current, rated rms current, AC impedance (ESR), and Q factor. Depending on the application, the choice of inductance type - shielded or unshielded - is also important.

The six points you need to know about patch capacitors

Chip capacitors are a type of capacitive material. The full name of chip capacitors is: multilayer (stacked, stacked) chip ceramic capacitors, also known as chip capacitors, chip capacitance. There are two ways to represent chip capacitors, one is in inches and the other is in millimeters. A capacitor, as the name suggests, is a "container for holding electricity" and a device that holds charges. English name: capacitor.

What are the applications of SMD capacitors in the electrical field?

Chip capacitors, as passive components, are commonly used in power circuits for functions such as bypass, decoupling, filtering, and energy storage. In signal circuits, their main functions include coupling, oscillation/synchronization, and time constant. Let's explain each of these separately.

What are the different types of dielectric materials for SMD capacitors?

The parameters such as X5R, X7R, Y5V, Z5U, COG, COH, etc. of chip capacitors describe the type of dielectric material used for capacitor acquisition, temperature characteristics, and error parameters. Different values also correspond to the range of capacitor capacity. What are the differences?

What are the methods for detecting chip capacitors

If the appearance is normal. The quality of capacitors can be tested and judged using a multimeter resistance range. Large capacity (1 μ Fixed capacitors with a rating of F or above can use the resistance range (R) of a multimeter × 1000) Measure the two electrodes of the capacitor, and the watch needle should swing in the direction of low resistance, then slowly swing back to around ∞. Next, exchange the test rod and try again to observe the swing of the watch needle. The larger the swing, the greater the capacitance of the capacitor.

What are the technical performance characteristics of electrolytic capacitor?

Range requirements of electrolytic capacitor, rated voltage range: 6.3V-400V DC; Operating temperature range: -55 ℃~+105 ℃; Nominal capacitance range: 0.1-6800uf; Leakage current (20 ℃): 1 ≤ 0.01CrUr (uA) or 3uA, whichever is greater (2 minutes)

What are the advantages of SMD inductors

Firstly, SMD inductors have the advantage of miniaturization, as they do not occupy too much space and are not affected by environmental factors. If it is applied to various small devices, it is also very suitable because the device itself has a relatively small volume, so there are also volume requirements for various internal pole components. In such a state, everyone can choose it first, Because it holds a unique advantage in terms of volume.

What is the reason why SMD capacitors are so widely used in the industry?

The volume and weight of SMT capacitors and resistors are only about 1/10 that of traditional plug-in components. After using SMT, the volume of electronic products is reduced by 40% to 60%, and the weight is reduced by 60% to 80%. High reliability, strong vibration resistance, low solder joint defect rate, good high-frequency characteristics, reduced electromagnetic and radio frequency interference, easy to achieve automation, improved production efficiency, and reduced costs by 30% to 50%.
