VXR250-2800S DC-DC Converter
The VXR250-2800S is optimized for a broad range of applications from military ground vehicles to commercial and military aircraft and is intended for harsh environments including severe vibration, shock and temperature cycling.
The VXR Series patented epoxy encapsulated V-SHIELD® packaging is highly resistant to chemical, solvent and salt environments and is fully compatible with high volume manufacturing processes including wave solder, cleaning solvents, high pressure sprays and aqueous wash processes. A unique integral six-sided metalized shield improves system EMI compatibility. Dual sided conduction cooling coupled with reduced power dissipation simplifies system thermal design.
