Product Features
● High Saturation Current — stable inductance under peak load and start-up inrush
● Open Magnetic Circuit — rod-type core resists saturation by design
● Ultra-Low DC Resistance — multi-strand oxygen-free copper, single-layer winding Wide Operating Temperature — -55 °C to +150 °C
● Broadband EMI Suppression — low-pass differential-mode filtering in LC / π networks
● Compact Through-Hole Body — axial or radial mounting for dense PCB layouts
● Optional Environmental Coating — polyolefin heat-shrink tubing or varnish
Product Advantages
● Keeps its inductance when the current surges. The open magnetic circuit holds the core out of saturation through load steps and start-up inrush.
● Less loss, less heat. A single-layer winding of multi-strand oxygen-free copper keeps DC resistance low, which cuts conduction loss.
● Built for hot, harsh locations. The construction is rated across a -55 °C to +150 °C operating window, so inductance and mechanical integrity hold up in engine-bay modules.
● One part does two jobs. Used as the low-pass element in an LC or π-filter network, it attenuates high-frequency switching noise while it smooths ripple.
● Simple structure, volume-ready cost. The unshielded rod body and single-layer winding use fewer parts and fewer process steps than a shielded bobbin design.
