## Summary description

TracoPower TCK-046 is a fixed-wire inductor with nominal inductance 18 mH and tolerance ±20%. Rated maximum DC current is 1.23 A. Compact package dimensions are 7 mm (width) × 7.8 mm (depth) × 5 mm (height). Suitable for use in power filtering, EMI suppression and energy storage in DC circuits. Supplied as 1 piece.

## Long description

TracoPower TCK-046 is a fixed-wire inductor with a nominal inductance of 18 mH and a tolerance of ±20%. It is designed for DC circuits where compact energy storage, power filtering and EMI suppression are required. The component is supplied as a single piece and features a small rectangular package with dimensions of approximately 7 × 7.8 × 5 mm, making it suitable for space‑constrained board layouts.
Advantages
The TCK-046 offers a relatively high inductance in a compact package and supports a rated maximum DC current of 1.23 A, providing a balance between energy storage and current handling. Its fixed‑wire construction ensures stable performance in power filter and suppression applications. The small footprint and low profile allow integration into tight designs without significantly increasing board area or stack height.
Suitable for
 Power filtering in DC power supplies and converters
 EMI suppression and noise reduction on supply lines
 Energy storage for small DC circuits and smoothing applications
 Compact electronic assemblies with limited board space
When it may not be suitable
This inductor has a tolerance of ±20% and may not be appropriate where tight inductance accuracy is required. It is rated for a maximum DC current of 1.23 A; applications demanding higher continuous currents or low DC resistance for minimal power loss will need a component with a higher current rating. The small package limits thermal dissipation compared with larger power inductors.
Key specifications
 Inductance: 18 mH
 Tolerance: ±20%
 Rated maximum DC current: 1.23 A
 Package dimensions (W × D × H): 7 × 7.8 × 5 mm
 Construction: fixed‑wire (through‑hole or compact PCB mount style)
 Supply quantity: 1 piece
How to use
Place the inductor in the circuit according to the schematic for power filtering, EMI suppression or smoothing. Observe correct orientation and soldering practices appropriate for the component style and your PCB. Ensure the expected DC current through the inductor does not exceed 1.23 A to avoid saturation or overheating. Verify board layout allows adequate clearance and, if necessary, provide thermal paths or spacing to improve heat dissipation.
What to consider before purchase
 Required inductance value and tolerance for your circuit
 Maximum continuous DC current in the intended application
 Available board area and component height constraints
 Thermal conditions and required power dissipation
Usage recommendations
For reliable performance, verify the inductor does not operate continuously near its maximum current rating and allow for tolerance variations in filter design. When used for EMI suppression, combine with appropriate capacitors and layout practices to achieve the desired attenuation.
