Overview
The TCM1608G-350-4P-T200 is a common mode filter manufactured by TDK Corporation, designed for signal line applications. It features a compact surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.4 mm height. The component operates within a temperature range of -25°C to +85°C and supports a maximum DC current of 100 mA. Key electrical specifications include an impedance of 35 Ohms 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
- Provides common mode noise suppression for high-speed signal lines
- Compact 1608 footprint suitable for space-constrained designs
- Supports reflow and iron soldering processes
Applications
- Signal line filtering in portable electronic devices
- Noise suppression in USB or data interface circuits
- EMC mitigation in consumer electronics
Procurement Notes
This component is officially classified as End of Life (EOL) by TDK Corporation. The product change notification indicates scheduled obsolescence with a discontinuation date. Designers must verify current availability through authorized distributors, as stock may be limited or exhausted. Replacement strategies should be initiated immediately to ensure supply chain continuity for ongoing production.
Selection Notes
Select this component only if the specific 35 Ohm impedance and 1608 package size are required for the design. Due to its EOL status, alternative components from the same family or newer generations should be evaluated for compatibility. Verify that the 100 mA rated current and 1.69 Ohms DC resistance meet the circuit requirements before finalizing the bill of materials.
Part Context
The TCM1608G-350-4P-T200 belongs to TDK's TCM-G series of common mode chokes. These components are engineered for EMC compliance in digital signal paths. The '1608' designation refers to the metric case size (1.6 x 0.8 mm). The suffix 'T200' typically denotes tape and reel packaging configuration for automated assembly.
Replacement Considerations
TDK recommends the TCM0605S-350-2P-T201 as a substitute model. Note that compatibility is not guaranteed due to differences in package size and channel count. Engineers must perform rigorous validation to ensure the replacement meets all electrical and mechanical constraints of the original design.
