2450BL05A0100001T

Overview

The Johanson Technology 2450BL05A0100001T is a surface-mount RF balun designed for wireless applications. It operates within a frequency range of 2.3 GHz to 2.69 GHz, centered on the 2.4 GHz ISM band. The component features a 1:2 impedance transformation ratio with 50/100 Ohm ports. Housed in an EIA 0202 (0505 metric) package, it supports SMD/SMT termination. Key electrical specifications include a maximum power rating of 2 W and insertion loss of 0.55 dB. The device functions reliably between -40°C and +85°C.

Feature Summary

• Provides balanced-to-unbalanced signal conversion for single-ended RF circuits
• Supports high-power transmission up to 2 Watts
• Optimized for compact PCB layouts using small footprint packaging

Applications

• Bluetooth Low Energy (BLE) modules
• Wi-Fi and WLAN transceivers
• Zigbee and IoT sensor nodes

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and exact pinout configuration before integration. Ensure that the receiving circuitry matches the 50/100 Ohm impedance requirements. Confirm availability through authorized distributors as supply levels may fluctuate. Cross-reference the mechanical dimensions against the target PCB land pattern to guarantee proper solder joint formation during assembly.

Selection Notes

Select this component when space constraints require a micro-balun solution for 2.4 GHz operations. It is suitable for designs needing 1:2 transformation ratios. Consider thermal management capabilities given the 2W rating. Evaluate insertion loss impact on overall link budget. Compare physical size against other available packages to optimize board real estate usage effectively.
