Standex Edge provides Through-Hole (THT) mounting options across a broad line of power inductors, particularly within its planar magnetics offerings. THT mounting is highly valued for high-reliability applications, such as defense and aerospace, because it is the most reliable mounting style for resisting mechanical vibration and mechanical shock.
The use of THT connections also supports increased current handling; certain low-power planar inductor packages (10W-1kW) realize a current rating that is 30% higher for THT applications. Standex planar inductors with THT options cover a massive power range, serving applications from low power (10W) up to high power (250kW).
Specific through-hole components include the PQ32 fixed power inductors with ferrite cores, designed for high-current POL converters. These inductors offer an inductance range of 0.9 to 6.0 µH and are rated for current typically between 45 to 60 A, up to a maximum of 80 A. These components are crucial for basic power system functions like filtering and ripple reduction.
