TCK-146

Fixed Inductors Overview

The TCK-146 is a surface-mount wirewound power inductor manufactured by Traco Power. It features an unshielded core design with an inductance of 10 µH ±20% measured at 1 kHz and 1 V. The component has a maximum DC resistance (DCR) of 350 mΩ and supports a rated current of up to 1 A. Its physical dimensions are 3.5 mm in length, 3.1 mm in width, and 2.1 mm in height. The device operates within a temperature range of -40°C to +85°C.

Fixed Inductors Feature Summary

• SMD wirewound construction for board-level mounting
• Unshielded magnetic core configuration
• Designed specifically for use with Traco isolated DC-DC converters

Fixed Inductors Applications

• Common mode chokes for Traco isolated DC-DC converters
• Board level power distribution systems
• Space critical applications requiring standard pinout compatibility

Fixed Inductors Procurement Notes

Verify the specific ordering code against official Traco Power documentation to ensure correct inductance and tolerance specifications. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range. Ensure PCB footprint matches the 3.5 x 3.1 mm SMD dimensions. Check for RoHS compliance status if required by project regulations.

Fixed Inductors Selection Notes

Select this component when designing circuits for Traco isolated DC-DC converters requiring a 10 µH common mode choke. Consider the 1 A current rating and 350 mΩ DCR limits during thermal analysis. The unshielded design may require consideration for electromagnetic interference in dense layouts. Verify mechanical height constraints against the 2.1 mm seated maximum dimension.

Fixed Inductors Part Context

The TCK-146 belongs to Traco Power's range of fixed inductors intended for use with their miniature isolated DC-DC converters, such as the TMA series. These components support board-level power distribution solutions where space efficiency and industry-standard pinouts are prioritized. The inductor complements Traco's portfolio of high-efficiency converters operating between -40°C and +85°C.
