20VDK1

Overview

The TE Connectivity Corcom Filters 20VDK1 is an enhanced performance K Series RFI power line filter designed for commercial applications. It provides common mode and differential mode filtering with high line-to-line attenuation. The unit supports a rated current of 20A at voltages up to 250VAC and operates at 50/60Hz frequencies. Maximum leakage current is specified at 0.4mA at 120VAC and 0.7mA at 250VAC. The component features a hipot rating of one minute line-to-ground and line-to-line, ensuring robust electrical isolation and safety compliance.

Feature Summary

• Provides enhanced common mode and differential mode RFI filtering
• Delivers higher line-to-line attenuation compared to standard VK series filters
• Engineered for cost-effective integration in applications without strict leakage current requirements

Applications

• Commercial electronic equipment requiring EMI suppression
• General purpose industrial machinery power inputs
• Non-patient care medical devices
• Portable equipment power modules

Procurement Notes

Verify that the application environment does not require the low leakage current specifications mandated by VDE portable equipment standards or UL544 non-patient care equipment regulations, as this model prioritizes cost-effectiveness over minimal leakage. Confirm that the 20A current rating and 250VAC voltage limit align with the system's maximum operational loads. Ensure compatibility with the required insertion loss characteristics for the specific frequency band of interference present in the target installation.

Selection Notes

Select this model when high line-to-line attenuation is necessary but strict leakage current limits are not enforced. Compare against the EDK series if lower leakage currents are required for specific regulatory certifications. Evaluate the physical mounting constraints and terminal connection types against the system chassis design. Consider the operating temperature range and environmental exposure conditions during the selection process to ensure long-term reliability.

Part Context

This component belongs to the DK Series of RFI power line filters from TE Connectivity Corcom Filters. The DK series is characterized by superior line-to-line attenuation capabilities compared to the VK series. The 20VDK1 variant specifically represents the V version, which offers the same high-performance filtering attributes within a more economical package structure suitable for broader commercial deployment scenarios.
