RP230-3.5-1-QD

Overview

The Astrodyne TDI RP230-3.5-1-QD is a single-phase, two-stage power line filter designed for chassis mounting. It features wire termination and operates at 250 VAC with a current rating of 3.5 A. The unit includes a capacitance of 1 nF and maintains a leakage current of 400 uA. Certified under UL, CSA, and EN standards, it supports 50 Hz and 60 Hz frequencies. Physical dimensions are 65 mm in length and 40 mm in height, with a maximum operating temperature of +40 C.

Feature Summary

• Dual-stage filtering architecture for enhanced noise attenuation
• Chassis mount design with wire termination for secure installation
• Compliance with major international safety and EMC standards

Applications

• Medical equipment power supplies
• Industrial control systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix QD confirms quick-connect or wire termination as per the official datasheet, as suffixes can vary by manufacturer revision. Confirm the exact capacitance value (1 nF vs 2.2 nF) matches your EMI requirements, as similar models like RP230-6.5-2.2-W exist. Ensure chassis mounting holes align with the 65x40 mm footprint. Check for RoHS compliance status if required by your supply chain policy.

Selection Notes

Select this model when dual-stage performance is required for sensitive loads within a 3.5 A limit. The low leakage current of 400 uA makes it suitable for medical applications where shock hazard must be minimized. Compare against single-stage alternatives if space is constrained, but note that two-stage designs offer superior high-frequency attenuation. Verify input voltage does not exceed 250 VAC.

Part Context

This component belongs to the RP230 series, which focuses on high-performance dual-stage filtration. Unlike the RP115 or RP120 series which are single-stage, the RP230 provides increased insertion loss. It differs from the RP225 series primarily in its specific current and capacitance ratings, tailored for lower current applications requiring robust noise suppression.

Replacement Considerations

The RP230-3.5-0-QD is a verified substitute with identical form factor but zero capacitance. For higher current needs, the RP230-6.5-2.2-W offers 6.5 A rating and 2.2 nF capacitance. Ensure any replacement maintains the same chassis mounting dimensions and termination style.
