TSL1N18D2G20LV0G9T

Overview

The TSL1N18D2G20LV0G9T is a multilayer ceramic low-pass RF filter from the TAIYO YUDEN TSL1 series. It features a center frequency of 2.2 GHz and a bandwidth of 1 GHz, with an insertion loss of 0.65 dB. The component operates at a 50 Ohm impedance within a 1.7 GHz to 2.7 GHz frequency range. It utilizes a 3-pin surface-mount package in the 0603 (1608 Metric) case size, measuring 1.6 x 0.8 x 0.65 mm.

Feature Summary

• Multilayer ceramic construction suitable for reflow soldering processes
• Halogen-free composition compliant with RoHS and REACH regulations
• Low insertion loss characteristics optimized for signal integrity

Applications

• W-CDMA communication systems
• CDMA network infrastructure
• GSM mobile devices
• LTE cellular equipment
• 5G wireless applications

Procurement Notes

Verify the complete part number including the suffix G9T to ensure correct tape-and-reel packaging configuration. Confirm that the 0603 footprint matches the target PCB layout dimensions. Ensure compatibility with standard lead-free reflow soldering profiles required for halogen-free components. Validate that the 50 Ohm system impedance aligns with the surrounding circuit design requirements.

Selection Notes

Select this component when a compact 0603 low-pass filter is required for frequencies around 2.2 GHz. The 1 GHz bandwidth provides specific attenuation characteristics distinct from wider or narrower band alternatives. Consider the 0.65 dB insertion loss for sensitive signal paths where minimal power degradation is critical. The small 1.6 x 0.8 mm footprint allows for high-density board layouts in portable devices.

Part Context

This device belongs to the TSL1 series of multilayer ceramic RF filters designed for modern wireless standards. It replaces previous part numbers such as FI168L2200G9-T within the manufacturer's portfolio. The series focuses on providing reliable signal conditioning in ultra-compact packages suitable for space-constrained mobile and communication hardware.

Replacement Considerations

The previous part number FI168L2200G9-T serves as a direct historical equivalent within the same product family. Verify pinout compatibility and exact dimensional tolerances before substituting with other generic 0603 low-pass filters.
