Through hole resistors are a type of fixed resistor which are placed directly into a circuit using a wire lead or lug. Through hole resistors offer many advantages such as being more reliable than surface mount resistors, being able to handle higher power without exceeding operating temperature limits, and providing good thermal and electrical stability over a wide temperature range. The H861K9BDA is a through hole resistor with a maximum power rating of 4W and resistance values ranging from 0.2 ohms to 1M ohms.

The construction of a through hole resistor begins with an insulating substrate that acts as a base for the resistor. Resistive material, such as wirewound, film, or carbon, is then deposited onto this substrate and its ends are connected to suitable electrical connectors. In the case of the H861K9BDA, the substrate is an alumina ceramic body with a ceramic outer sleeve which is flameproof to offer maximum safety and reliability.

The H861K9BDA is widely used in many applications, from consumer and automotive electronics to military and industrial systems. It is suitable for use with many types of voltage sources, such as DC, AC, and PWM (pulse-width modulation). As a general purpose resistor, the H861K9BDA can effectively reduce the peak current and voltage levels in a circuit. It can also be used to provide current limiting protection and to limit inrush current during power-up.

The H861K9BDA is designed to exhibit excellent electrical properties in a wide temperature range while dissipating heat quickly and safely. It has a voltage rating of 250V, surge rating of 500V, and absorptive power rating of 1.2W. Its ceramic body and outer sleeve offer excellent heat resistance and protection against mechanical shock. Its low internal resistance allows it to handle higher power levels and maintain electrical stability over a wide temperature range.

In addition to providing excellent thermal and electrical stability, the H861K9BDA offers a number of unique features that make it a popular choice for a wide range of applications. For example, it features a low inductance construction which helps to limit RF emissions, and it offers resistance values up to one megohm which is ideal for mitigating EMC problems. Its high insulation resistance makes it suitable for use in high-temperature environments. And its overall size is small enough to fit into limited space applications.

The H861K9BDA is a reliable and versatile through hole resistor that can be used in a wide range of applications. It offers excellent thermal and electrical stability over a wide temperature range and is suitable for use with many types of voltage sources. Its unique features make it a popular choice for a variety of applications. It is a reliable and cost-effective solution for many applications.
