FSLM2520
17
The FSLM2520 Series is a ferrite core wirewound surface
mount chip inductor which conforms to the EIA standard
1008 footprint. Its proprietary welded termination architec-
ture offers superior reliability and high heat-resistance for flow
and reflow soldering capability. It is an economical choice
for general signal conditioning, RF or IF filtering applications,
or as matching elements.
Features
• Inductance Range: 0.1-220µH
• Temperature Coefficient: 750ppm/°C
• Temperature Range: –40°C to +85°C
• Typical max Q: 40 ~ 50
• Proprietary wire-wound structure with welded
terminations offers high reliability
• Superior solderability and high heat-resistance for flow
and reflow soldering
• Low profile: 1008 footprint 1.7mm max (1.6mm typ.)
• S-parameter data available upon request
• Packaged on tape and reel in 2,000 piece quantity
