Power Inductors - Shielded
From 1.0 µH to 100 µH
Not Shown at Actual Size
CHARACTERISTICS
Description: SMD Shielded Power Inductor
Applications: Mainly used as a power source inductor for mobile
phones, HDDs, LCD panels and DSCs.
Operating Temperature: -40°C to +105°C (includes self temp.
rise)
IDC1: Based on inductance change (ΔL/L0: < 30%) at ambient
temp. 25°C
IDC2: Based on temperature rise (ΔT: 40°C Typ.)
Rated Current: IDC1 or IDC2, whichever value is lower.
Resistance to Solder Heat: 260°C 10 secs.
Inductance Tolerance: ±20%, ±30%
Testing: Inductance is tested on an HP4284A at 100KHz, 0.1V
Packaging: Tape & Reel
Marking: Parts are marked with letter identifier.
Miscellaneous: RoHS Compliant.
Additional Information: Additional electrical & physical
information available upon request.
Samples available. See website for ordering information.
