2450BM07A0004001T

Overview

The 2450BM07A0004001T is a signal conditioning component manufactured by Johanson Technology Inc., specifically designed as a balanced-unbalanced (balun) transformer. It operates within the 2.4 GHz to 2.5 GHz frequency range, with a center frequency of 2.45 GHz and a bandwidth of 50 MHz. The device utilizes an EIA 0402 surface-mount package, measuring 1.0 mm in length and 0.5 mm in width. It supports an operating temperature range from -40°C to +85°C and features SMD/SMT termination for PCB integration.

Feature Summary

• Functions as a matched balun transformer for RF signal conversion
• Optimized for 2.4 GHz ISM band applications including Bluetooth and WiFi
• Compact EIA 0402 footprint suitable for space-constrained designs

Applications

• Bluetooth Low Energy (BLE) transceivers
• WiFi 802.11 b/g/n modules
• Zigbee wireless sensor networks
• NRF24L01 compatible interfaces

Procurement Notes

Verify the global manufacturer part number against official Johanson Technology documentation to ensure compatibility, as distributors may list variations or obsolete revisions. Confirm that the EIA 0402 package dimensions align with your PCB footprint library. Check RoHS compliance status directly on the datasheet, as regulatory requirements vary by region and production batch. Ensure the supplier provides valid traceability for the specific lot code to guarantee performance consistency.

Selection Notes

Select this component when a compact, matched balun solution is required for 2.4 GHz single-ended to differential signal conversion. The EIA 0402 size offers a balance between performance and board area efficiency compared to larger packages. Consider the -40°C to +85°C operating range for industrial or consumer environments. This part is suitable for designs prioritizing minimal insertion loss and high isolation in tight spatial constraints.
