BSF-C88108+

Overview

The BSF-C88108+ is a lumped LC band stop RF filter manufactured by Mini-Circuits. It operates within a frequency range of 88 MHz to 108 MHz, with a center frequency of 98 MHz and a bandwidth of 20 MHz. The component features an insertion loss of 5 dB and is designed for 50 Ohm impedance systems. It utilizes a surface mount package in a 14-SMD module configuration, measuring 22.10 mm in length, 20.32 mm in width, and 6.35 mm in maximum height. The device supports a power level of 24 dBm and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Lumped LC architecture for effective signal conditioning
• Surface mount design for automated PCB assembly
• Defined stopband attenuation characteristics

Applications

• RF signal filtering in communication systems
• Interference suppression in receiver front-ends
• Signal conditioning in test and measurement equipment

Procurement Notes

Verify the specific ordering suffix against official Mini-Circuits documentation to ensure correct termination style and packaging format. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits. Ensure compatibility with standard SMD reflow processes given the 14-SMD module footprint. Cross-reference the datasheet version to validate current RoHS compliance status before finalizing procurement orders.

Selection Notes

Select this component when a fixed 20 MHz bandwidth rejection is required around 98 MHz. The 50 Ohm impedance matches standard RF transmission lines. Consider the physical dimensions for PCB layout constraints. Verify that the 24 dBm power handling meets system requirements. Evaluate thermal management needs for operation near the upper temperature limit.
