ATC, the industry leader, is introducing the new 506WLS
Series High Frequency Ultra-Broadband Inductor (UBL).
This unique component provides low insertion loss and
an excellent match over multiple octaves of frequency
spectrum.
The 506WLS is ideal for ultra-broadband DC decoupling
networks and bias tee applications in optical
communications systems and equipment using high-
speed digital logic.
Advantages:
• Ultra-Broadband Performance
• Ultra-Low Insertion Loss
• Flat Frequency Response
• Excellent Return Loss Through 40 GHz
• Unit-to-Unit Performance Repeatability
• Rugged Powdered Iron Core
ATC # 001-1120
Rev. G; 8/17
Electrical Specifications:
• Inductance: 3.30 µH ±10%*
• Rated DC Current (IDC max.): 350 mA**
• DC Resistance (RDC typ.):
1.15 𝛀, typ. at +20°C, 10 mA current.
* Inductance: measured at 1 MHz, 0.1 Vrms, 0 mA dc
with HP4291A impedance analyzer
** Current Rating: based on a 100 °C temperature rise
from a 25°C ambient.
