概述

Description

I can’t identify 2450AT43B100E from the string alone. It’s likely a specific electronic component (IC, regulator, sensor, capacitor/resistor network, etc.) whose meaning depends on the manufacturer and package.
How to get a precise introduction quickly:
- Find the manufacturer logo or supplier code on the part or its packaging.
- Search the exact part number on distributor sites (Digi-Key, Mouser, Arrow) or the manufacturer’s site.
- Open the datasheet to confirm: type, package/pinout, electrical specs, operating range, and typical applications.
- Check the circuit context (where it’s used on the board) to confirm its role.

Package

2450AT43B100E is a 2.45 GHz ceramic chip antenna in a surface-mount (SMD) package — a compact surface-mount chip antenna.

Pinout

2450AT43B100E is a 2.45 GHz chip antenna with a two‑pad interface: one RF feed pad (signal) and one ground pad (may be implemented as one or more ground lands on the package/PCB). Function: provides the radiating element for 2.4–2.5 GHz ISM/WLAN applications; the feed pad connects to your 50 Ω RF feed through any required matching network, and the ground pad(s) must be tied to the PCB ground plane per the manufacturer’s recommended footprint for proper tuning and performance.

Manufacturer

The 2450AT43B100E is made by Johanson Technology (also marketed as Johanson Dielectrics). Johanson is a U.S.-based manufacturer of RF/microwave passive components — chip antennas, ceramic resonators/filters, RF capacitors and related parts for wireless, IoT and RF communications applications.
