WSL18 Power Metal Strip® High Power Resistors

Vishay / Dale WSL18 Power Metal Strip® High Power Resistors offer twice the power of standard WSL (from 2.0W to 0.20W), as well as extremely low resistance values (down to 0.0005Ω). With all welded construction and solid metal Nickel-Chrome or Manganese-Copper alloy resistive element with low TCR (<20ppm/ºC), the WSL18 Series are ideal for all types of current sensing, voltage division, and pulse applications including switching and linear power supplies, instruments, and power amplifiers. The Vishay / Dale WSL18 Series Power Metal Strip High Power Resistors feature solderable terminations, very low inductance (0.5nH to 5nH), and excellent frequency response to 50MHz.
