LADD Distribution
DEUTSCH Diodes and Resistors in both directions. Resistors protect sensitive electronics by limiting the amount of electricity that can flow to the device through the resistor, and therefore preventing power spikes. For example, resistors are used to prevent power surges from burning out an LED by restricting current flow to the light. DEUTSCH industrial diode and resistor connectors are easily added to an application after the fact if unwanted power surges are discovered.
