0433BM41A0019001E

Overview

The 0433BM41A0019001E is a surface-mount signal conditioning component manufactured by Johanson Technology Inc. Designed for the ISM band, it operates within a frequency range of 424 MHz to 444 MHz. The device integrates a balun and low-pass filter (LPF) into a single SMD package, providing impedance matching with 50 Ohm unbalanced and balanced ports. It features a 180-degree phase difference and supports standard PCB mounting via SMD/SMT termination. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates balun and low-pass filter functions in a compact SMD package
• Provides impedance matching between 50 Ohm unbalanced and balanced ports
• Maintains 180-degree phase difference for signal integrity

Applications

• ISM band wireless communication systems
• Sub-GHz RF front-end circuits
• Signal conditioning for transceivers requiring balanced-to-unbalanced conversion

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead times prior to ordering. Ensure storage conditions meet specified temperature ranges to maintain performance integrity. Cross-reference datasheet revisions to confirm pinout and electrical specifications match design requirements.

Selection Notes

Select this component for applications requiring integrated impedance matching and filtering in the 433 MHz ISM band. Consider the SMD form factor for space-constrained PCB layouts. Evaluate thermal performance within the -40°C to +85°C operating range. Compare against discrete solutions to assess size and cost benefits of the integrated balun-LPF design.
