WCL2520-121-R RF Inductors-SMD Chip Inductor by Eaton Electronics
Introducing the WCL2520-121-R, a high-performance surface-mount chip inductor manufactured by Eaton Electronics, designed for a wide range of RF and electronic applications. This wire wound chip inductor features compact dimensions of 2.92 x 2.79 x 2.1 mm, making it ideal for space-constrained designs.
Product Features
Package: 1008 (2520 metric) with Tape & Reel packaging (2000 parts per reel)
High Q value for efficient RF performance
Tight inductance tolerance within ±5%
Inductance range from 0.12 µH to 220 µH
RoHS compliant and moisture sensitivity level (MSL): 1
Suitable for applications including IoT, computing, smart meters, industrial equipment, M2M, mobile phones, wearables, wireless LAN, Bluetooth, WiFi, antenna, and RF transceiver modules
Operating temperature range: -40 °C to +85 °C
Solder reflow compliant with J-STD-020 (latest revision)
Unfortunately I havent tested the 5G, Only difficult part was connecting antennas. But everything is good, by default it runs on Qualcom's QMI mode, Had to switch to MBIM and it works good with Windows. Planning to run with OpenWRT soon.
