HHV1WSFT-73-270K

Through Hole Resistors are widely used in the field of electronics and electrical engineering, due to their low cost and reliable performance. The HHV1WSFT-73-270K is a popular Through Hole Resistor, classified as a power film resistor. It is typically used in power system applications such as motor control and protection circuits, as well as power conversion systems.

The HHV1WSFT-73-270K is a fixed power resistor with an extended power rating of 270 Watts. It is designed for use with positive and negative temperature coefficient thermistors, which allow it to provide reliable performance over a wide temperature range from -55°C to +100°C. The resistor has a nominal resistance value of 73 ohms and a maximum operating voltage of 350 Volts.

The construction of the HHV1WSFT-73-270K is such that it consists of two main components: a tinned metal base film and a hard sintered resistor element. The base film is composed of electrolytic copper tape that is affixed to a solid backing film. The sintered resistor element is glued directly to the copper tape. This base film is then coated with a thick plastic coating, which gives it improved electrical properties and resistance to corrosion. The sintered resistor element is composed of a metal-oxide mixture, which is resistant to high temperature and has a low temperature coefficient.

In terms of mechanical properties, the HHV1WSFT-73-270K exhibits excellent long-term reliability, with a lifetime expectancy of up to 100,000 hours. Its temperature coefficient is low and it exhibits a low noise level, making it ideal for use in power system applications. The resistor also offers low dynamic resistance, providing excellent power dissipation.

The HHV1WSFT-73-270K is used as an active component in a system or circuit. It is connected between two points and absorbs a certain amount of power from the circuit, based on the value of the resistor. It then releases a certain amount of heat, based on the power being dissipated. This is known as the power dissipation principle. Depending on its resistance value, it can be used as either a current regulator (to reduce current in a circuit) or as a voltage regulator (to reduceVoltage in a circuit).

The HHV1WSFT-73-270K can also provide protection against over-current and over-voltage, making it an ideal choice for high-power electrical applications. It is also able to dissipate significant amounts of heat without causing permanent damage, making it suitable for use in high temperature and overload conditions. The resistor is also extremely stable, meaning it can maintain a consistent resistance over time. This makes it ideal for long-term use in electronic systems and circuits.

Overall, the HHV1WSFT-73-270K is an excellent Through Hole Resistor, offering reliable performance over a wide temperature range and in high-power applications. It is easy to assemble, offers excellent electrical properties, and is capable of dissipating large amounts of heat without degrading its performance. This makes it an ideal choice for any electronic system or circuit requiring a reliable and durable power resistor.
