High Voltage MELF Resistor

The High Voltage MELF Resistor stands out with its SMD-enabled structure, allowing for high power delivery in compact, space-saving packages. With a versatile power rating that spans from 0.16W to 3W and a broad resistance range of 100K ohms to 68M ohms, it meets the diverse needs of numerous applications.

Designed for demanding environments, this resistor is capable of handling working voltages much higher than those of general-purpose resistors, making it a perfect fit for high-voltage applications. Additionally, its heat dissipation capabilities surpass those of chip resistors, ensuring that it maintains optimal performance even under high-power conditions.

Moreover, the High Voltage MELF Resistor boasts a sturdy mechanical structure that can withstand vibration and thermal shock, providing enhanced durability and reliability in harsh environments. This makes it an excellent choice for applications where resilience and long-term stability are crucial.
