The H838K3DYA Through Hole Resistors are designed to address difficult power protection applications where fast response with very low leakage current, high energy pulsed protection and durability in harsh environments are required. Accurate operation over a wide temperature range of -55°C to +125°C is also important for these applications. The resistors are available with different power ratings from 2W to 6W and three resistance values from 24k Ω to 270kΩ.

The working principle behind H838K3DYA Through Hole Resistors lies in its use of so-called “bleeder resistor” technology. Resistor bleeder technology utilizes an internal resistor and capacitor combination to rapidly dissipate charge when the circuit is activated. The combination of these components works together to actively quadrupole or “bleed” off positive energies, increasing protection from voltage spikes, EMI, and other issues active in the electrical system.

The H838K3DYA Through Hole Resistors have a variety of applications. For example, they can be used in automotive applications, such as fuel injection systems, brake systems, power steering systems, and other electric or electronic systems subjected to shock or vibration. Used in such cases, these resistors help to reduce the potential of component damage and malfunctions.

In industrial applications, the H838K3DYA Through Hole Resistors provide low-contact-resistance and higher voltage-drop characteristics, which helps to reduce the effects of noise and electromagnetic interference. These resistors can also be used to protect computer and medical devices from long-term static voltages. These protection resistors are also particularly suited to power supplies to protect sensitive components from excessively high current flow.

The H838K3DYA Through Hole Resistors also have applications in telecommunications networks. In these cases, the resistors filter feedback, reduce voltage variances, and protect radio-frequency amplification stages from damaging power surges. These resistors are also used in switching applications to reduce transient currents and eliminate transients due to positive circuit inductance.

Overall, the H838K3DYA Through Hole Resistors are designed to meet the demanding needs of the power protection industry. With a wide variety of applications, fast response, low leakage current, and high energy pulsed protection, these resistors make valuable additions to a wide range of industries.
