HHV1WSFT-73-8M45

Through hole resistors, such as the HHV1WSFT-73-8M45, are an essential component in many electronic circuits. These discrete resistors allow for precise current control and are available in two major forms: thick film and thin film. HHV1WSFT-73-8M45 resistors have an application field and working principle that depend on the type of resistor.

Thick film through hole resistors are more commonly found in older electronic systems and consist of a ceramic base with a network of vacuum deposited metal film. The metal film consists of two layers, a high temperature resistant layer (a mixture of glass and oxides) and a resistive layer. As current passes through the resistor, the resistive layer requires energy to move it to a higher energy state, reducing the current. This is where the resistance value of the resistor is derived from.

The application field of a thick film resistor is mainly in high-temperature environments (such as military applications, or applications where temperature stability is necessary) where precision is important. HHV1WSFT-73-8M45 thick film resistors also have a good noise immunity, making them suitable for noisy environments. Additionally, they are more durable and have a higher thermal range than other resistors, making them suitable for high-temperature applications.

Thin film through hole resistors, such as the HHV1WSFT-73-8M45, are more commonly used in modern electronic systems. These resistors are composed of a ceramic base covered with a thin metal layer, usually with photocopically printed connections. Unlike thick film resistors, which use a conversion of kinetic energy in order to reduce current flow, thin film resistors reduce the current by purely resistive means, along with capacitive and inductive heating effects.

The application field of a thin film resistor is mainly in low-noise environments where precision and accuracy are important. HHV1WSFT-73-8M45 thin film resistors have a very low noise immunity, making them suitable for low-noise applications. Additionally, they are more tolerant to temperature variations, making them suitable for temperature-sensitive applications. They are also lighter and more compact than thick film resistors, making them suitable for applications where size and weight are a concern.

In conclusion, HHV1WSFT-73-8M45 through hole resistors have different application fields and working principles depending on the type of resistor. Thick film resistors are more suitable for high-temperature applications, while thin film resistors are more suitable for low-noise applications. Both types of resistors offer precise current control, making them essential components in many electronic systems.
