FI212B190223-T

Overview

The FI212B190223-T is a surface-mount bandpass filter manufactured by Taiyo Yuden, designed for radio frequency signal conditioning. It operates with a center frequency of 1.907 GHz and features a bandwidth of 46 MHz. The component exhibits an insertion loss of 1.7 dB and maintains a 50 Ohm impedance. Packaged in a compact 0805 (2012 metric) SMD/SMT footprint with four pins, it supports board mounting within an operating temperature range of -30°C to +85°C.

Feature Summary

• Provides selective RF filtering with defined passband characteristics
• Utilizes a compact surface-mount package for space-constrained designs
• Ensures impedance matching for standard RF transmission lines

Applications

• Wireless communication modules requiring 1.9 GHz band filtering
• RF front-end circuits in mobile devices
• Signal conditioning in industrial radio equipment

Procurement Notes

Verify the specific revision level and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 0805 package dimensions align with your PCB layout constraints. Ensure the operating temperature range meets your environmental requirements. Check for any recent product change notifications that may affect performance specifications or availability.

Selection Notes

Select this component when a narrow 46 MHz bandwidth is required around 1.907 GHz. The low insertion loss of 1.7 dB makes it suitable for sensitive RF paths. Consider the 0805 package size relative to available board space. Verify compatibility with your system's 50 Ohm impedance network to minimize reflection losses.

Part Context

This part belongs to the FI212 series of high-frequency filters from Taiyo Yuden. These components are engineered for signal conditioning in wireless applications. The series offers various center frequencies and bandwidths to suit different RF standards. The FI212B190223-T specifically targets the 1.9 GHz region.

Replacement Considerations

Direct substitutes include other 0805 bandpass filters with similar 1.9 GHz center frequencies and comparable bandwidths. Verify pinout compatibility and electrical parameters such as insertion loss and impedance. Consult manufacturer cross-reference lists for validated alternatives.
