TSB1N18D5G53LV0FWT

Overview

The TSB1N18D5G53LV0FWT is a bandpass filter from Taiyo Yuden, designed for LTE and Wi-Fi applications. It operates within a frequency range of 5.15 GHz to 5.925 GHz. The component features a nominal impedance of 50 Ohms and an insertion loss of 1.2 dB. It utilizes a surface-mount device (SMD/SMT) package in the 0603 (1608 metric) dimension, measuring 1.6 x 0.8 x 0.65 mm. The device supports board mounting and functions reliably within an operating temperature range of -40°C to +85°C.

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for stable temperature characteristics and high performance.
• Offers compact thin packaging to minimize design footprint while maintaining low insertion loss and high attenuation.

Applications

• LTE wireless communication systems
• Wi-Fi signal processing modules

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required tape-and-reel quantities. Confirm RoHS3 compliance status if environmental regulations apply. Cross-reference the previous part number FI168B5538FW-T during inventory transitions to prevent sourcing errors. Ensure the supplier provides official datasheets matching this exact model designation for accurate technical validation.

Selection Notes

Select this component when a 0603 footprint is required for frequencies between 5.15 GHz and 5.925 GHz. Consider the 1.2 dB insertion loss specification for signal integrity requirements. Evaluate the LTCC construction benefits for thermal stability in environments ranging from -40°C to +85°C. Compare against other bandpass filters in the same series for size or performance trade-offs.
