2450BP39D0100B001E

Overview

The Johanson Technology Inc. 2450BP39D0100B001E is a discontinued surface-mount bandpass RF filter designed for the 2.45GHz ISM band. It features a 100MHz bandwidth and 2.5dB insertion loss. The component utilizes a 1008 (2520 Metric) package with four PCB pads, measuring 2.50mm x 2.00mm x 1.05mm. It complies with RoHS3 standards and carries an EAR99 classification.

Feature Summary

• Miniaturized integrated passive design for space-constrained applications
• Optimized electrode layout for high Q-factor performance
• Suppression of spurious responses up to the third harmonic

Applications

• Industrial, Scientific, and Medical (ISM) band equipment
• Wireless sensor networks operating at 2.45GHz
• Short-range radio frequency communication modules

Procurement Notes

This component is officially discontinued and no longer manufactured by Johanson Technology Inc. Verification of availability requires checking secondary market distributors or obsolete inventory lists. Designers must confirm end-of-life status before finalizing specifications. Sourcing should prioritize verified substitute components to ensure long-term supply chain stability and compliance with current production requirements.

Selection Notes

Selection is limited due to the part's discontinued status. Engineers should evaluate alternative components that match the 2.45GHz center frequency, 100MHz bandwidth, and 1008 package dimensions. Compatibility checks must verify insertion loss and spurious response suppression levels against original design constraints. Substitution strategies should focus on maintaining signal integrity within the ISM band while ensuring mechanical fit.

Part Context

This filter belongs to Johanson Technology’s integrated passive device portfolio, utilizing coplanar waveguide technology. The design employs half-wavelength resonators on a double-sided circuit board to achieve miniaturization. This specific model represents an optimized version aimed at reducing size while maintaining performance metrics required for industrial applications.
