The NS1535 is a noise suppressor designed by TE Connectivity Laird for reducing power line noise in audio frequency and RF ranges. It operates with a maximum supply voltage of 35 Volts DC. The unit supports a current rating of 15 Amps at a 50% duty cycle (5 minutes on, 5 minutes off) and 12 Amps for continuous operation. It features a low-pass filter design to protect against transient ignition spikes.
Verify the specific manufacturer designation when sourcing, as the component is associated with both TE Connectivity and Laird Technologies. Confirm the current rating requirements match your application's duty cycle, distinguishing between the 15-amp intermittent and 12-amp continuous limits. Ensure compatibility with 1-35 VDC systems before integration.
Select this component for applications requiring suppression of ignition noise and RF interference on power lines. It is suitable for environments where transient spikes are common. Consider the physical size and wire gauge requirements for installation in tight spaces typical of marine or automotive audio setups.
This noise suppressor belongs to a category of EMC/EMI line filters used to clean power inputs for sensitive electronic equipment. Similar products often focus on specific frequency bands or current capacities, but this model is specifically engineered for general audio and RF interference reduction in vehicle and marine power systems.
