Working Principle of the H4287KBYA

The H4287KBYA is a through-hole type resistor which comprises two parts: an external metal case and an internal resistor element. The resistor element is a precise metal oxide film resistor which is produced using a deposition technique. This technique provides good uniformity, high accuracy, and excellent stability. The external metal case provides excellent insulation from the resistor element, protects against shocks and vibration, and increases the absolute temperature range of operation. The through-hole pins are provided as leads, allowing the resistor to be soldered simply and quickly to the circuit board.

The H4287KBYA has a thermal temperature coefficient of 0.05%, ensuring backup performance even in extreme conditions. It is available in various values from 0.5kΩ up to 22kΩ with a ±1% tolerance. The H4287KBYA is designed to be mounted horizontally on the circuit board or vertically with legs bent downward to provide some additional cooling to the resistor element. This will reduce the resistor’s temperature coefficient.

The H4287KBYA is a reliable and cost-effective resistor that is well-suited for a variety of applications requiring good accuracy and stability. Its through-hole design facilitates simple and quick mounting, and its hermetically sealed case ensures excellent environmental protection.
