The high frequency transformers’ Solder

Introduction：

1) After soldering, PIN foot is smooth and free from foreign matter.

2) The thread end should not be higher than the convex point.

3) After soldering, BOBBIN is complete, no damage and short foot phenomenon.

4) Welding oil (flux) residual less, no tin, no short circuit.

5) The adhesive tape has no damage tolerance.

6) Solder at least a full circle.

7) There can be no transverse tin tip after soldering

                      Basic knowledge of Inductor Choke Coils Inductance coils are made of wires wound around an insulating tube one by one. The wires are insulated from each other. The insulating tube can be hollow, or it can contain iron cores or magnetic powder cores, referred to as inductors. Expressed by L, the units are Henry (H), Milli Henry (mH), Micro Henry (uH), 1H=10^3mH=10^6uH. A. Classification of inductance Classified according to the form of inductance: fixed inductance, variable inductance. According to the nature of the magnetic conductor: air core coil, ferrite coil, iron core coil, copper core coil. Classified by work nature: antenna coil, oscillating coil, choke coil, trap coil, deflection coil. Classified by winding structure: single-layer coil, multi-layer coil, honeycomb coil. B. the main characteristic parameters of the inductance coil 1. Inductance L The inductance L represents the inherent characteristics o...

Unlocking the Secrets of Low-Frequency Transformers:  Core Area and Tongue Mouth Essentials Low-frequency transformers play a crucial role in electrical systems, enabling the efficient conversion of voltage for various applications. In this article, we will delve into the fundamentals of these transformers, focusing on core cross-sectional area, tongue mouth dimensions, and their significance in transformer design. Core Cross-Sectional Area: The core cross-sectional area, often represented as E in EI- type transformers , is a vital parameter for transformer design. It refers to the E-piece within the core, positioned horizontally in the middle of the transformer bobbin. This area plays a  significant role in determining the overall performance of the transformer. Tongue Mouth Dimensions: The dimensions of the tongue mouth are critical for ensuring efficient power transmission and performance of the transformer. Tongue mouth dimensions typically include a width of 96 mm and a...
