PLF-27D1-3A-W

Overview

The PLF-27D1-3A-W is a single-phase EMI/RF line filter manufactured by Adam Tech. It features a metal case and wire leaded termination for chassis mounting. The component is rated for 115 VAC or 250 VAC operation with a current capacity of 3 A. Designed for 50 Hz and 60 Hz frequencies, it provides two-stage filtering to suppress electromagnetic interference in power lines.

Feature Summary

• Two-stage EMI/RF filtering capability
• Metal case construction for durability
• Wire leaded termination style
• Chassis mount installation method

Applications

• Industrial equipment power input stages
• Communication system power supplies
• Medical device internal power filtering

Procurement Notes

Verify the specific voltage rating (115 VAC vs 250 VAC) required for your application against the datasheet specifications. Confirm that the wire leaded termination style matches your assembly process. Ensure the chassis mounting dimensions are compatible with your enclosure design before ordering.

Selection Notes

Select this model when a compact, metal-cased EMI filter is needed for low-current applications up to 3 A. The wire leaded option suits through-hole PCB or direct wiring connections. Consider the two-stage filtering performance if higher attenuation is required compared to single-stage alternatives.

Part Context

This component belongs to the PLF series of power line filters from Adam Tech. These filters are designed to meet EMC standards by reducing conducted emissions. The series offers various current ratings and mounting options to suit different power supply requirements across industrial and commercial sectors.

Replacement Considerations

Check for equivalent models with similar 3 A ratings and metal case constructions. Verify that any substitute maintains the same wire leaded termination and chassis mounting compatibility. Ensure the replacement meets the same frequency and voltage specifications.
