TSH1N18D2G49LS0FBT

Overview

The TSH1N18D2G49LS0FBT is a high-pass RF filter from Taiyo Yuden, designed for LTE applications. It features a center frequency of 2.495GHz with a bandwidth of 390MHz. The device exhibits an insertion loss of 1.5dB within the passband range of 2300MHz to 2690MHz and provides 35dB attenuation outside this range. Packaged in a compact 0603 (1608 Metric) surface-mount format, it operates reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Compact and low-profile design suitable for space-constrained mobile devices
• Low insertion loss combined with high attenuation for effective signal filtering
• Stable temperature characteristics ensuring consistent performance under varying conditions

Applications
