Overview
The SCM25-T15-102T-RC is a surface mount common mode choke manufactured by Allied Components International. It features a two-line configuration designed for signal line filtering applications. The component operates within a temperature range of -40°C to +125°C and supports a maximum current rating of 1.5A. It exhibits an impedance of 1 kOhm at the specified frequency and maintains a maximum DC resistance (DCR) of 300 mOhm.
Feature Summary
- Provides common mode noise suppression for dual-line circuits
- Designed for surface mount assembly processes
- Capable of handling high current loads up to 1.5A
Applications
- Signal line filtering in electronic systems
- Noise suppression in data transmission interfaces
- EMI reduction in compact circuit boards
Procurement Notes
Verify the specific impedance value and current rating against your schematic requirements before ordering. Confirm that the surface mount footprint matches your PCB layout constraints. Ensure the operating temperature range meets the environmental conditions of the final assembly. Cross-reference the manufacturer part number with official distributor catalogs to confirm authenticity and availability status.
Selection Notes
Select this component when dual-line common mode noise attenuation is required in space-constrained designs. The 1.5A current rating suits moderate power signal lines. Consider the 300 mOhm DCR impact on signal integrity if low loss is critical. Evaluate the thermal performance at the upper limit of the specified temperature range for reliability.
Part Context
This component belongs to the SCM25 series of common mode chokes from Allied Components International. The series includes variants with different impedance levels and current ratings, such as the SCM25-900T-RC. These components are typically used in conjunction with other passive filters to meet electromagnetic compatibility standards in consumer and industrial electronics.
Replacement Considerations
Direct substitutes must match the 1.5A current rating, 1 kOhm impedance, and 300 mOhm DCR specifications. Verify pinout compatibility and physical dimensions for direct replacement. Check thermal characteristics to ensure equivalent performance under load.
