2450BM14E0003001T

Overview

The Johanson Technology 2450BM14E0003001T is a matched balun and band pass filter designed for the Nordic Semiconductor nRF51822 chipset. It operates within a frequency range of 2.4 GHz to 2.5 GHz with a bandwidth of 50 MHz. The device utilizes a 6-pin EIA 0603 (1608 metric) ceramic passive package with SMD/SMT termination. It supports an impedance of 50 Ohms and functions reliably between -40°C and +85°C.

Feature Summary

• Integrates balanced-to-unbalanced conversion and filtering in a single compact component
• Optimized specifically for Nordic Semiconductor nRF51822 wireless applications
• Utilizes robust ceramic construction for stable RF performance

Applications

• Nordic Semiconductor nRF51822 based wireless designs
• Bluetooth Low Energy (BLE) transceiver circuits
• IoT sensor modules requiring integrated signal conditioning

Procurement Notes

Verify the specific suffix and manufacturer part number against official Johanson Technology documentation to ensure compatibility with target chipsets. Confirm RoHS compliance status and lead times through authorized distributors, as availability may vary by region and production cycle.

Selection Notes

Select this component when designing for the Nordic nRF51822 platform to simplify the RF front-end layout. The integrated balun and filter reduce component count compared to discrete solutions. Ensure the 0603 footprint aligns with the PCB design constraints and thermal requirements for the operating temperature range.

Part Context

This part belongs to Johanson Technology's BM series of passive devices. It serves as a critical interface component between the RF transceiver and the antenna, ensuring signal integrity in the 2.4 GHz ISM band. The device replaces separate balun and filter components, streamlining the design process for compact wireless modules.
