WKL
Non-Wrapped Electrode General Purpose Current Sense Resistors
Our WKL series, available in various sizes, excelling in heat dissipation, low noise, tight resistance tolerance, and long-term stability. Its high-power capacity suits power modules, DC/DC converters, and motor drive modules. Differentiating from our WEL series, its unwrapped electrode design maximizes PCB space, reduces noise, and offers both short-side and long-side electrode configurations.
