Through Hole Resistors are one of the most popular types of resistors used today. The CA00021R800KE05 is a through-hole resistor designed to meet the requirements of many electronic applications, from power and automotive electronics to RF electronics and industrial applications. In this article, we will look at the application field and working principle of the CA00021R800KE05.

Application Field

The CA00021R800KE05 offers a high precision resistor that is suitable for a wide range of applications. This resistor is designed to provide reliable, yet cost-effective operation in applications such as: power supplies, signal conditioning, noise suppression, power amplifiers, and telecommunications. This resistor is also ideal for automotive electronics, industrial control and instrumentation, RF electronics, and other precision applications. The resistor is UL Rated, RoHS Compliant, and comes with an ANSI-standard datasheet, warranty, and conformal coating option.

Working Principle

The CA00021R800KE05 utilizes a unique design which couples high precision with excellent thermal performance. The resistor is constructed from an alumina ceramic substrate with a metal film element. The metal film element is evaporated or sputtered on to the ceramic substrate and adheres firmly to the surface. The substrate provides a stable platform upon which the metal film is formed. The high temperature process results in an extremely durable element with excellent operational characteristics. The metal film element provides high precision performance at potentially high temperatures.

The CA00021R800KE05 offers excellent electrical characteristics. This includes a very low resistance tolerance of 0.1%, a temperature coefficient of resistance (TCR) of ±30ppm/°C, and a long-term stability of ±0.2% per year. The package size is extremely small as well, with a size of just 5.0 mm × 2.5 mm × 10 mm.

The CA00021R800KE05 also comes with an integrated heat sink. The integrated heat sink allows heat energy to be efficiently and quickly dissipated from the element. This in turn helps to reduce the effects of self-heating and improves device reliability.

The CA00021R800KE05 is a through-hole resistor which provides a reliable and cost-effective solution for a wide range of applications. Its high precision performance and integrated heat sink provide excellent thermal performance and stability. Its UL rating, RoHS compliance, and ANSI-standard datasheet makes it ideal for interface and signal conditioning applications.
