74889502450

Overview

The Würth Elektronik part number 74889502450 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 2.5 dBi. Its physical dimensions are 5.2 mm in length, 2.1 mm in width, and 1 mm in height. This internal SMT antenna is engineered for integration into compact electronic devices requiring reliable wireless connectivity.

Feature Summary

• Surface mount multilayer construction for automated assembly
• Internal design suitable for space-constrained applications
• Optimized for 2.45 GHz ISM band operations

Applications

• Wireless local area network (WLAN) modules
• Bluetooth low energy (BLE) devices
• Zigbee and other 2.4 GHz IoT sensor nodes

Procurement Notes

Verify that the specific order matches the 74889502450 identifier to ensure correct frequency and package specifications. Confirm compliance with RoHS and REACH regulations as indicated in official documentation. Check for AEC-Q200 qualification if automotive application requirements apply. Ensure storage conditions maintain moisture sensitivity level integrity prior to reflow soldering.

Selection Notes

Select this component when a low-profile internal antenna is required for 2.4 GHz wireless protocols. The 5.2 x 2.1 mm footprint suits dense PCB layouts where external antennas are impractical. Consider the 2.5 dBi gain performance against system link budget requirements. Evaluate thermal management capabilities during high-power transmission phases.

Part Context

This component belongs to the WE-MCA family of multilayer chip antennas from Würth Elektronik. These antennas utilize proprietary ceramic materials to achieve stable electrical performance across temperature variations. The series supports various form factors tailored for different mounting orientations and spatial constraints in modern consumer electronics.

Replacement Considerations

Consult official Wurth Elektronik substitution guides for direct equivalents. Verify that any alternative maintains identical 2.45 GHz center frequency and 50 Ω impedance. Ensure mechanical dimensions do not exceed the 5.2 x 2.1 x 1 mm envelope. Confirm radiation pattern compatibility with existing enclosure designs.
