SF2432D

Overview

The SF2432D is a high-performance Surface Acoustic Wave (SAW) filter designed for RF signal conditioning. It operates with a center frequency of 475 MHz and features a bandwidth of 10 MHz, covering the range from 470 to 480 MHz. The component exhibits an insertion loss of 3.2 dB and is rated for a maximum voltage of 3 V. It utilizes a 50 Ohm impedance interface and is housed in a compact 3.8 x 3.8 mm surface-mount package. The device complies with Directive 2002/95/EC (RoHS) standards and has a Moisture Sensitivity Level of 1.

Feature Summary

• High-performance SAW technology for precise RF signal filtering
• Compact 3.8 x 3.8 mm surface-mount package design
• Compliance with RoHS environmental directives

Applications

Procurement Notes

Verify the specific ordering suffix, such as TR for tape and reel packaging, when placing orders to ensure correct handling specifications. Confirm that the supplier provides official datasheets matching the SF2432D part number. Ensure compliance with moisture sensitivity level requirements during storage and assembly processes. Check for AEC-Q200 qualification if automotive grade reliability is required for the specific application context.

Selection Notes

Select this component when a 475 MHz center frequency with 10 MHz bandwidth is required for signal conditioning. Consider the 3.2 dB insertion loss and 3 V rating against system power constraints. The 3.8 x 3.8 mm footprint suits space-constrained designs. Verify compatibility with 50 Ohm system impedance to minimize signal reflection and ensure optimal performance in the target RF circuit.
