Overview
The Vicor Corporation 36-00037 is a surface-mount common mode choke designed for high-current applications. It features an inductance of 330 µH measured at 1 kHz and supports a maximum current rating of 20A. The component utilizes a two-line configuration to suppress electromagnetic interference. Its low direct current resistance of 5 mOhm ensures minimal power loss during operation. This filter type is engineered for integration into compact electronic systems requiring robust noise attenuation.
Feature Summary
- Surface mount construction for automated assembly
- Two-line filtering capability for differential noise suppression
- High current handling capacity up to 20A
Applications
- Power supply input filtering
- DC-DC converter EMI suppression
- Telecommunications equipment noise reduction
Procurement Notes
Verify the specific datasheet version before procurement, as some sources list conflicting inductance values such as 420 µH. Confirm the manufacturer is Vicor Corporation and not a generic alternative. Ensure the surface mount package dimensions match your PCB footprint requirements. Cross-reference the 20A current rating with your thermal management design to prevent saturation or overheating issues during peak load conditions.
Selection Notes
Select this component when high current capacity is required alongside significant common mode noise attenuation. The 330 µH inductance provides effective filtering for lower frequency interference. Consider the surface mount form factor for space-constrained designs. Evaluate the 5 mOhm DCR impact on overall system efficiency. Ensure the operating temperature range meets your environmental specifications.
Part Context
This component belongs to Vicor's line of magnetic filters and chokes. It is distinct from Vicor's DC-DC converters, which are listed in other search results. The part number 36-00037 specifically identifies this passive filtering element within the broader Vicor portfolio of power management solutions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternatives.
