2450BP39D100C001E

Overview

The Johanson Technology Inc. 2450BP39D100C001E is a surface-mount RF bandpass filter designed for the 2.45 GHz ISM band. It features a center frequency of 2.45 GHz with a bandwidth of 100 MHz and an insertion loss of 1.2 dB. The component utilizes a 1008 (2520 metric) package with four printed circuit board pads, measuring 2.50 mm in length, 2.00 mm in width, and a maximum height of 1.05 mm. It operates within a temperature range defined by standard industrial specifications.

Feature Summary

• Provides selective signal filtering for the 2.45 GHz wireless communication spectrum
• Integrates passive components into a compact surface-mount footprint
• Supports high-volume manufacturing through standardized reel packaging

Applications

• Wireless Local Area Network (WLAN) transceivers
• Bluetooth Low Energy (BLE) modules
• Zigbee and IEEE 802.15.4 devices
• Industrial, Scientific, and Medical (ISM) equipment operating at 2.4 GHz

Procurement Notes

Verify the specific suffix '001E' against the manufacturer's current global part numbering change documentation to ensure functional equivalence with legacy designations. Confirm RoHS3 compliance status and Moisture Sensitivity Level (MSL) ratings prior to assembly planning. Cross-reference the DigiKey and Mouser distributor identifiers to validate supply chain availability and lead times for the active production version.

Selection Notes

Select this component when a low-profile 1008 package is required for space-constrained PCB layouts. The 1.2 dB insertion loss offers efficient signal transmission compared to higher-loss alternatives. Ensure the design accommodates the 1.05 mm maximum height constraint. Verify that the 100 MHz bandwidth aligns with the specific channel requirements of the target wireless protocol.

Part Context

This device belongs to the Johanson BP series of integrated passive bandpass filters. These components replace discrete LC networks to reduce board space and improve consistency. The 2450 prefix indicates operation in the 2.4 GHz ISM band, while the 39D designation typically correlates with the 1008 package size and specific electrical performance characteristics optimized for consumer electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult the manufacturer's official substitution guide or engineering support for validated equivalents.
