Chip resistor can handle 3000V

OHMITE HVC Series of wrap around terminal chip resistors is available with voltage ratings up to 3Kv and resistance values from 100k up to 100Gohms. Devices have a standard TCR of 100ppm and standard tolerances of 5%, although tolerances as low as 0.50% can be achieved. Voltage coefficients range from as low as 10 and up to 100 depending on resistance value. Supplied in 0805, 1206, and 2512 package sizes, the range comprises 23 stock part numbers. The thick film devicdes have an operating temperature range of -55C to +155C and the matte tin contact with a nickel barrier is designed for extended shelf life.
