B033ND5S

Overview

The B033ND5S is a surface mount bandpass filter manufactured by Knowles Dielectric Labs. It operates within a frequency range of 3.1 GHz to 3.5 GHz, centered at 3.3 GHz with a bandwidth of 400 MHz. The device features an insertion loss of 2.5 dB and maintains a system impedance of 50 ohms. Designed for robust performance, it supports operating temperatures from -55°C to +125°C.

Feature Summary

• Provides signal conditioning through bandpass filtering capabilities
• Engineered for surface mount technology integration
• Maintains stable electrical characteristics across extended temperature ranges

Applications

• RF signal processing in communication systems
• Frequency selection in wireless infrastructure
• Signal conditioning in high-frequency electronic circuits

Procurement Notes

Verify the specific datasheet version and mechanical dimensions prior to implementation. Confirm that the 50-ohm impedance matches the target circuit design requirements. Ensure the operating temperature range aligns with the environmental conditions of the final assembly. Cross-reference the package type with the intended PCB footprint to guarantee physical compatibility.

Selection Notes

Select this component when a fixed center frequency near 3.3 GHz is required. The 400 MHz bandwidth suits applications needing moderate frequency selectivity. Consider the 2.5 dB insertion loss impact on overall system gain. Evaluate the surface mount form factor against available board space constraints.

Part Context

This part belongs to the bandpass filter category within the Knowles Dielectric Labs portfolio. It serves as a passive signal conditioning element designed for RF environments. The component utilizes ceramic or similar dielectric materials typical for high-frequency stability. It complements other RF components in transmitter and receiver front-end architectures.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify that any replacement maintains the 3.1-3.5 GHz operational range and 50-ohm impedance. Ensure thermal and mechanical specifications match the original design constraints.
