Overview
The TCM1608G-650-4P-T200 is a four-channel common mode filter manufactured by TDK Corporation. It features a compact surface-mount design with dimensions of 1.6 mm x 0.8 mm x 0.4 mm. The component operates within a temperature range of -25°C to +85°C and provides an impedance of 65 Ohms at 100 MHz. Key electrical specifications include an inductance of 93 nH, a maximum DC current rating of 100 mA, and a maximum DC resistance of 1.69 Ohms. This device is part of the TCM-G series and utilizes SMD/SMT termination for PCB mounting.
Feature Summary
- Four-channel configuration for multi-line signal filtering
- Compact 1608 package size suitable for space-constrained designs
- Surface-mount technology compatible with reflow soldering processes
Applications
- High-speed data line protection
- Common mode noise suppression in digital circuits
- Signal integrity enhancement in communication interfaces
Procurement Notes
Verify end-of-life status before procurement as the manufacturer has scheduled this item for discontinuation. Confirm that the 65 Ohm impedance specification meets system requirements. Ensure compatibility with existing PCB footprint and soldering profiles. Check for available alternative components if supply chain continuity is critical for long-term production.
Selection Notes
Select this component when four independent channels require common mode noise attenuation in a minimal footprint. The 100 mA current rating suits low-power signal lines rather than power delivery paths. Verify that the 1.69 Ohms DC resistance does not introduce excessive voltage drop in the specific application circuit. Consider thermal performance within the specified -25°C to +85°C operating range.
Part Context
This component belongs to the TCM-G series of common mode chokes from TDK Corporation. These devices are designed for suppressing electromagnetic interference on high-speed data lines. The series offers various impedance values and channel configurations to accommodate different signal integrity needs in modern electronic systems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the end-of-life status, engineers should evaluate equivalent four-channel common mode filters with matching 1608 dimensions and similar electrical characteristics from other manufacturers.
