H4P487RDCA

Through Hole Resistors

Through hole resistors are one of the most common types of resistors in electrical and electronic circuits. They are used to reduce or limit current, voltage, or power in an electrical system. The H4P487RDCA is an example of such resistor. It is a low-cost axial-leaded stepped-tolerance resistor with a power rating of 1/2 watt.

H4P487RDCA Application Field and Working Principle

The H4P487RDCA is used for many basic applications in industrial, military, aerospace, and civil engineering fields. It is used as a voltage divider, current limiter, and for matching of impedances. The H4P487RDCA is also used as a protective device for various signal lines and circuits. It is commonly used in high temperature and radiation environments.

The working principle of the H4P487RDCA is quite simple. It consists of two metal leads separated by a ceramic body. The ceramic body has two layers of metal resistive material which acts like an insulator. When a voltage is applied across the resistor, a small electric current will flow through it. This current is limited by the resistance created by the ceramic body, thus limiting the voltage, current, or power in a particular circuit. In order to adjust the resistance level, the resistor must be disconnected from the circuit and the ceramic body can be replaced by a different type of material with a different resistance value.

The H4P487RDCA is available in different packages and tolerances. The package sizes include radial leaded and axial leaded. The rating of the resistor is 1/2 watt and the resistance tolerance is 5%. The operating temperature range is 0°C to +150°C.

The H4P487RDCA is also available in a copper capacitor version. This version is used to reduce radio frequency interference (RFI) and electromagnetic interference (EMI). The copper capacitor version of the resistor provides better noise immunity in high-frequency applications.

The H4P487RDCA is a low-cost, robust, and reliable through-hole resistor. It is suitable for a wide range of applications. The resistor is capable of withstanding high temperatures and has good stability over time. It is also resistant to vibration, shock, and corrosion. This makes it the ideal choice for both automotive and industrial applications.
