T1515-30MH High Power Common Mode Inductor EMI Filter for Industrial Power Supplies
The windings are formed from high-strength flat copper wire rather than round wire. The flat conductor has a larger surface area, which reduces skin and proximity effects at higher frequencies and helps dissipate winding heat, so the choke keeps its filtering performance under load.

Product Features
● 30mH High Inductance: Minimum / typical inductance of 30mH for strong common mode impedance.
● High Power up to 5A: Carries currents of up to 5A in industrial power supply applications.
● 10kHz - 1MHz Frequency Range: Filters common mode noise across the band where conducted interference appears.
● Flat Copper Wire Winding: High-strength flat conductor instead of round wire.
● Lower Losses and Better Heat Dissipation: The larger flat-wire surface reduces skin and proximity effects and spreads heat over a wider area.
● Horizontal (H) and Vertical (V) Options: Two mounting orientations for flexible PCB layout.
● Insert-Type Through-Hole Pins: Pins are soldered directly into the board.
● Wide Operating Temperature: -40°C to +85°C.
● Compact Design: A small board footprint that suits dense power supply layouts.
Product Advantages
● High common mode impedance from a 30mH winding: attenuates the common mode noise in the 10kHz to 1MHz band.
● Flat copper wire instead of round wire: the larger conductor surface reduces skin and proximity effects.
● Better heat spreading: the flat wire presents more surface area to the surrounding air.
● Current capability up to 5A: sized for industrial power supply duty at the currents those supplies draw.
● Two mounting orientations: the same part can be laid out horizontally or vertically.
● Robust through-hole termination: insert-type pins form a strong mechanical joint with the board and are straightforward to solder in volume.
● Wide operating temperature range, -40°C to +85°C: suitable for equipment operated in demanding environments.
● Compact construction: the insulated winding assembly keeps the footprint small on dense boards.

Application Specifications
Industrial power supplies
The common mode filtering stage on the supply input, which is the application field specified for the part.
Power supply unit builds
Mounted on the PSU board as the board-level filter choke beside the bulk capacitor and heatsink.
High-density power boards
The compact body and insert-type pin mounting suit boards with little free area.
Equipment that has to meet conducted-emission limits
30mH of common mode impedance between 10kHz and 1MHz provides attenuation across the noisy band.
