Uses professional capacitors for reliable, stable performance. The winding is made with high temperature resistant copper-clad aluminum enamelled wire for durability and consistent characteristics under heat. Includes a pre-attached cable terminal that eliminates the need for soldering, speeding up setup and maintenance. The large power switch provides four selectable settings, including two 6 dB and two 12 dB attenuation options, allowing precise level control. Key benefits - High-quality components for dependable operation - Heat-resistant construction suited to demanding environments - Solder-free wiring for faster, easier assemblies - Flexible attenuation options for fine-tuning signals Recommended use scenarios - Laboratory or bench testing where precise attenuation is required to calibrate signal chains - Electronics repair or hobby projects where soldering is to be avoided or is impractical - Field service or production environments that need quick switching between attenuation levels Specifications and features at a glance - Professional capacitors - Copper-clad aluminum enamelled wire winding - Pre-installed cable terminal (no soldering needed) - Large four-position switch with two 6 dB and two 12 dB settings This description preserves the original product's functions and technical attributes while presenting clear, customer-friendly information.
