BLF2012LL98R2400A

Balun Overview

The BLF2012LL98R2400A is a combo balun filter manufactured by Pulse Electronics, designed for signal conditioning in the 2.4 GHz to 2.5 GHz frequency range. It features a 50 Ohm impedance and operates within an 0805 (2012 Metric) surface-mount package. The component provides a typical insertion loss of 3.5 dB and is rated for operation across standard industrial temperature ranges. This integrated solution combines balun and filtering functions to support compact RF circuit designs.

Balun Feature Summary

• Integrates balun and filter functions into a single compact surface-mount device
• Optimized for 2.4 GHz to 2.5 GHz wireless signal conditioning applications
• Designed for high-volume production with standard 0805 footprint compatibility

Balun Applications

• Bluetooth Low Energy (BLE) transceivers
• Wi-Fi module antenna interfaces
• Zigbee and IoT wireless sensor nodes

Balun Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Pulse Electronics or authorized distributors before procurement. Confirm that the 0805 land pattern matches your PCB design guidelines. Ensure the operating temperature range aligns with your system's environmental requirements. Cross-reference the part number suffixes to confirm availability and packaging options such as tape and reel quantities.

Balun Selection Notes

Select this component when space constraints require combining balancing and filtering functions in a 2.4 GHz ISM band application. The 0805 package size suits dense PCB layouts where multiple RF components are needed. Consider the 3.5 dB insertion loss impact on overall link budget. Verify impedance matching with the connected RF transceiver and antenna port to ensure optimal signal transfer and minimal reflection.

Balun Part Context

This part belongs to Pulse Electronics' portfolio of RF signal conditioning components. It falls under the category of combo balun filters, which are essential for converting differential signals to single-ended signals while providing harmonic suppression. These components are critical for maintaining signal integrity in modern wireless communication devices operating in crowded frequency bands.
