Overview
The RBBPF3225180CB7B1U is an RF bandpass filter manufactured by Walsin Technology Corporation. It operates with a center frequency of 1.175 GHz and supports a bandwidth range of 1125 MHz to 1225 MHz. The component utilizes a surface-mount device (SMD) package in the 1210 (3225 metric) dimension, measuring 3.20 mm x 2.50 mm. This shielded ferrite chip bead is designed for high-frequency signal integrity applications.
Feature Summary
- Provides precise bandpass filtering within the 1125-1225 MHz range
- Features a compact 1210 surface-mount footprint for space-constrained designs
- Includes shielding to minimize electromagnetic interference
Applications
- RF signal processing circuits
- Wireless communication modules
- High-frequency data transmission systems
Procurement Notes
Verify the specific datasheet version for accurate electrical characteristics before integration. Confirm that the 1210 package dimensions align with your PCB layout constraints. Ensure compatibility with your assembly process regarding the SMD termination type. Cross-reference the manufacturer part number to avoid confusion with similar ferrite beads or filters from other series.
Selection Notes
Select this component when a fixed center frequency of 1.175 GHz is required. The 1210 package offers a balance between performance and board space. Consider the shielded construction if EMI suppression is critical. Verify that the operating frequency range matches your system's specific channel requirements.
Part Context
This part belongs to Walsin's RF filter portfolio, specifically designed for radio frequency applications. It differs from standard ferrite beads by offering defined passband characteristics rather than broad-spectrum noise suppression. The 3225 metric size is common in consumer electronics and industrial RF equipment.
Replacement Considerations
No public substitute part numbers are confirmed in the provided documentation. Direct replacements must match the 1.175 GHz center frequency and 1210 package dimensions. Verify impedance and insertion loss specifications against the original design requirements.
