Filter Inductors
High Current
FEATURES
• Printed circuit mounting (axial leads)
• Protected by polyolefin tubing
RoHS
• High saturation bobbin used allowing high
inductance with low DC resistance
COMPLIANT
ELECTRICAL SPECIFICATIONS
• Pre-tinned leads
• High resistivity core offers very high parallel resistance,
resulting in maximum coil performance
Inductance: Measured at 1.0 V with no DC current
Incremental Current: The typical current at which the
inductance will be decreased by 5 % from its initial zero DC
value
• 20 sleeveless models available at reduced cost
Dielectric Rating: 2500 VRMS between winding and outer
circumference to within 0.250" [6.35 mm] of the insulating
sleeve edge
Operating Temperature: - 55 °C to + 125 °C (no load)
- 55 °C to + 85 °C (at full rated current)
MECHANICAL SPECIFICATIONS
Wire: Solid soft copper
Terminals: 20 AWG tinned copper leads
Coating: Polyolefin tubing - flame retardant UL type VW-1
per MIL-I-23053/5, Class 3 requirements
Current Rating: Maximum continuous Operating current
(DC or RMS) based on a 40 °C temperature rise
Core Material: Ferrite
