High Voltage resistor with the size from 0402 to 2512, resistance up to 100M ohm , offers Max overload to 4000V in 2512, 3000V in 2010.
Thick Film special design to achieve high working voltage and stability in SMD chip resistors. One of the key function resistors in a circuit is detecting high voltage by voltage dividing. Rated voltage and maximum working voltage are specified for each resistor, which should not be exceeded when it is used. This specification applies to all sizes of rectangular-type fixed chip resistors with Ruthenium-base as material. HVR series offers the high voltage which can reduce using the numbers of resistors. Save cost and space. Generally, the higher resistance is against higher voltage.

    Professional High Voltage Thin Film MELF Resistors are a specialized type of resistor. The thin film construction allows for precise control of the resistance value and offers excellent stability and accuracy. MELF (Metal Electrode Leadless Face) design gives them certain advantages such as a compact form factor and good heat dissipation characteristics. These resistors are engineered to handle high voltages, making them ideal for applications in high-voltage power supplies, voltage dividers in high-voltage circuits, and some high-voltage measurement and testing setups. Their high reliability and performance in high-voltage conditions ensure the proper functioning and safety of the electrical systems they are incorporated into.
