Filter Inductors
High Current
FEATURES
• Printed circuit mounting (axial leads).
• Protected by polyolefin tubing.
• High saturation bobbin used allowing high inductance with low DC resistance.
• Pre-tinned leads.
• High resistivity core offers very high parallel resistance, resulting in maximum
coil performance.
• 20 sleeveless models available at reduced cost.
ELECTRICAL SPECIFICATIONS
Inductance: Measured at 1V with no DC
current.
Incremental Current: The typical current
at which the inductance will be decreased
by 5% from its initial zero DC value.
Dielectric Rating: 2500VRMS between
winding and outer circumference to within
0.250" [6.35mm] of the insulating sleeve
edge.
Operating Temperature:
- 55°C to + 125°C (no load).
- 55°C to + 85°C (at full rated current).
Current Rating: Maximum continuous.
Operating current (DC or RMS) based on a
40°C temperature rise.
