Filter Inductors
High Current
FEATURES
• Printed circuit mounting.
• Pre-tinned leads.
• Protected by polyolefin tubing - flame retardant UL type VW-
1 per MIL-I-23053/5, Class 3 requirements.
APPLICATIONS
Noise filtering for switching regulators, power amplifiers,
power supplies and SCR and Triac control circuits.
ELECTRICAL SPECIFICATIONS
Inductance: Measured at 1.0V with zero DC current.
Current Rating: Maximum continuous operating
current (DC or RMS) based on a 50°C temperature rise.
MECHANICAL SPECIFICATIONS
Wire: Solid soft copper.
Terminals: Extensions of the winding.
Core Material: Ferrite.
Incremental Current: The typical current at which the
inductance will be decreased by 5% from its initial zero DC
value.
Operating Temperature: - 55°C to + 125°C (no load).
- 55°C to + 75°C (at full rated current).
Coating: Polyolefin tubing.
