SXBP-202+

Overview

The SXBP-202+ is a surface-mount lumped LC band pass filter designed for RF applications. It operates with a center frequency of 202 MHz and an 8 MHz bandwidth, covering the range from 198 to 206 MHz. The component maintains a 50 Ohm impedance and exhibits an insertion loss between 3.4 and 5 dB. Packaged in an 8-SMD, no-lead form factor, it utilizes miniature high-Q capacitors and wire-welded inductors to ensure high reliability and consistent performance across production lots.

Feature Summary

• Features fast rejection roll-off for increased selectivity against adjacent channels
• Utilizes miniature high-Q capacitors and wire-welded inductors for high reliability
• Provides repeatable performance across production lots

Applications

• RF signal filtering
• IF stage filtering
• Microwave circuit design

Procurement Notes

Verify the specific datasheet version for the SXBP-202+ to confirm exact electrical tolerances and thermal characteristics. Ensure compatibility with standard SMD reflow profiles during assembly. Cross-reference the part number suffix to confirm lead-free compliance status as indicated by the plus sign. Confirm package dimensions match the PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a narrow 8 MHz bandwidth is required around the 202 MHz center frequency. The 50 Ohm impedance matches standard RF systems. Consider the SMD package for automated assembly needs. Evaluate the insertion loss specifications against system sensitivity requirements. Verify that the physical size fits within the available board space constraints.

Part Context

This component belongs to the Mini-Circuits SXBP series of surface-mount band pass filters. The series offers various center frequencies optimized for different RF and IF applications. These filters are engineered for use in communication systems requiring precise frequency selection. The manufacturer designs these units to provide consistent performance in compact electronic assemblies.

Replacement Considerations

Check for other SXBP series variants with similar center frequencies if the 202 MHz specification is flexible. Verify pinout and footprint compatibility before substituting with components from other manufacturers. Ensure replacement parts meet the same 50 Ohm impedance and bandwidth requirements.
