Overview
The Würth Elektronik 74889302450 is a WE-MCA series multilayer chip antenna designed for surface-mount technology. It operates within the 2400-2500 MHz frequency range, centered at 2.45 GHz. The component features a 50 Ω impedance and delivers a peak gain of 0.5 dBi. Its physical dimensions are 3.2 mm in length, 1.6 mm in width, and 1.2 mm in height. This internal SMT antenna is engineered for compact wireless applications requiring reliable RF performance.
Feature Summary
- Surface-mount multilayer construction for automated assembly
- Internal design suitable for space-constrained enclosures
- Optimized for 2.45 GHz ISM band operations
Applications
- Wireless local area network (WLAN) devices
- Bluetooth low energy (BLE) modules
- Zigbee and other 2.4 GHz IoT sensor nodes
Procurement Notes
Verify that the specific order matches part number 74889302450 to ensure correct 2.45 GHz tuning. Confirm surface-mount compatibility with your PCB footprint. Check for RoHS compliance status if required by your manufacturing standards. Ensure storage conditions maintain moisture sensitivity level integrity prior to reflow.
Selection Notes
Select this component when a low-profile internal antenna is required for 2.45 GHz applications. The 3.2 x 1.6 mm package suits tight spatial constraints compared to larger external alternatives. Consider the 0.5 dBi gain requirement against system link budget needs. Verify that the 50 Ω impedance aligns with the transceiver output stage.
Part Context
This part belongs to the Würth Elektronik WE-MCA family of multilayer chip antennas. These components are specifically developed for high-volume consumer electronics and industrial IoT devices. The series emphasizes reliability and consistent radiation patterns in small form factors, supporting modern wireless communication standards.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 3.2x1.6x1.2mm footprint, 2.45 GHz center frequency, and 50 Ω impedance characteristics precisely.
