H4357KBZA

Understanding the H4357KBZA through hole resistors is an important requirement to implement them into a circuit board. A knowledge of their application field and working principle as well as the key specifications will enable you to make the right design decisions. Through hole resistors are manufactured in various types, including metal oxide film, carbon and ceramic composition resistors. H4357KBZA through hole resistors are amongst the most popularly used of all these. Essentially, they comprise of a sealed hollow cylinder of ceramic, with ends of nickel or silver plated metal, inserted with a conductive material. Through the movement of the conductive material, the part forms a resistance. H4357KBZA through hole resistors have the advantage of being long-life, with better temperature stability and better performance than other types used in circuit boards.

To understand the H4357KBZA application field and working principle, one needs to get familiar with the parts and the features they offer. First of all, these resistors are relatively large and heavy, compared to the other types of resistors, providing excellent thermal capacity. Consequently, H4357KBZA through hole resistors are popularly used in circuits where a high power loss with low heat generation is needed. This combination is what makes the part suitable for protecting the circuit during high voltage over-loads and power surges.

In terms of its working principle, H4357KBZA through hole resistors operate on the simple principles of Ohm’s law – where the resistor’s resistance changes in proportion to the voltage and/or current. The resistance of the resistor is determined by the internal material within the resistors, and can be adjusted by changing the physical material of the resistor. The resistance is unchanged until a high voltage or temperature changes the free electrons or induces them to move between the electrodes. In terms of its application field, these resistors are used in various circuits, for the purpose of controlling or limiting the current in a circuit. Common application areas are digital logic, power supplies, mobile phones, consumer electronics, medical electronics, automotive and aeronautic industries, and military electronics.

H4357KBZA through hole resistor has a 50 ohm range with a power dissipation of up to 3 watts. and a low temperature coefficient of about 0.2%. The dimensions of the part are quite uniform, making it ideal for mounting on a PCB board. The terminals of the resistor also come in different shapes, such as round, square and rectangular, to suit different applications. The resistors also come with various insulation and protection layers, including varnish, paint, enamel or ceramic for use in high or low temperature applications.

There is no doubt that H4357KBZA through hole resistors offer an excellent combination of features and specifications. The part is widely used in many industries due to its stability and robustness. It has a good tolerance and temperature coefficient making it a viable alternative to other types of resistors available in the market. In short, this resistor is one of the best resistors available and has been widely adopted by the industry for its dependability.
