Thin-Film Inductors
TDK Corp. of America
TOKYO, Sept. 22, 2025 — 
Products in the PLEC69B series 10-µH thin-film inductors from TDK Corporation are used for separating the data signal from the power in optical transceivers in AI data centers. Bias-tee circuits, which are used in these transceivers, are designed to superimpose signals and power on a single transmission line. Because of the impedance characteristics, inductors like PLEC69B separate the signal from the power in bias-tee circuits, preventing the signal from flowing into the power side. The inductor has a wide frequency range of 10-200 MHz. The DC resistance is 1.4 Ω and features a rated current of 0.2 A. The PLEC69B ensures high reliability with an upper operating temperature limit of <125 °C.
