Through Hole Resistors

The H422KDZA is a unique resistor designed for use in through-hole applications. It is characterized by its high accuracy and low insertion loss. The H422KDZA is designed for applications that require accurate resistance values with low tolerance. The resistor is comprised of two parts: the main body and a crimpable capacitor.

Construction

The H422KDZA is constructed from a custom-molded high temperature resistance alloy called “Volt-R®”. The resistor consists of a hollow cylindrical metal body, with a diameter of 4.5 mm and a height of 22 mm. A split-ring crimpable capacitor is crimped onto the top of the resistor body, forming the inner all-metal housing.

Performance

The H422KDZA is designed to achieve very low insertion loss of <0.05 dB. It is also highly stable, exhibiting a temperature coefficient of only 0.1‰/°C (0.0001%). With its low temperature coefficient, users can be assured of near-perfect accuracy regardless of temperature variation. The H422KDZA is also designed for reliable operation, with a calculated life expectancy of 10 years.

Applications

The H422KDZA is designed to be used in a variety of through-hole applications, including: power supply regulation, voltage regulation, signal isolation, and RF shielding. It is well suited for use in applications that require near-perfect accuracy with low insertion loss. Its low temperature coefficient also makes it ideal for use in temperature-sensitive applications.

Working Principle

The H422KDZA operates by passing an alternating current (AC) through the resistor. The resistor, combined with the crimpable capacitor, converts the AC voltage into a DC voltage, according to Ohm’s law. This DC voltage is then converted back into AC by the capacitor. The end result is an accurate, low-noise, low-loss resistor.

Conclusion

The H422KDZA is a unique, high-accuracy, low-loss resistor designed specifically for through-hole applications. With its split-ring crimpable capacitor, it offers superior accuracy and low insertion loss. It is well suited for use in power regulation, voltage regulation, signal isolation, and RF shielding applications. The H422KDZA’s low temperature coefficient and long life expectancy make it an ideal choice for temperature sensitive applications.
