ZRC273A

Overview

The ZRC273A is a feedthrough capacitor manufactured by EMI Filter Company, designed for high-frequency electromagnetic interference suppression. It features an axial bushing package suitable for bulkhead mounting applications. The component has a capacitance of 0.027 µF (27,000 pF) and a voltage rating of 50 VDC. It utilizes X7R dielectric material to ensure stable performance across varying temperatures. The device provides an insertion loss of 42 dB at 100 MHz, indicating effective signal attenuation in the radio frequency spectrum.

Feature Summary

• Provides effective electromagnetic interference filtering through feedthrough capacitor design
• Features X7R temperature coefficient dielectric for consistent electrical characteristics
• Supports direct bulkhead or panel mounting via axial bushing configuration

Applications

• Radio frequency circuit shielding
• Power supply line filtering
• Signal cable termination for noise reduction

Procurement Notes

Verify that the specific order matches the EMI Filter Company manufacturer designation rather than generic equivalents. Confirm the axial bushing dimensions align with the intended panel cutout requirements. Ensure the 50V DC rating meets the operational voltage constraints of the target circuit. Check RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when high-frequency noise suppression is required at bulkhead interfaces. The 0.027 µF value offers a balance between capacitance and self-resonant frequency characteristics. Consider the 42 dB insertion loss metric for critical RF isolation needs. The through-hole mounting style requires appropriate mechanical support during installation.

Part Context

This part belongs to the low-pass filter series produced by EMI Filter Company, a division of Nordquist Dielectrics. The ZRC273A is specifically engineered as a bulkhead-mounted solution for integrating capacitive filtering directly into chassis panels. It serves as a dedicated component for creating shielded boundaries in electronic enclosures.

Replacement Considerations
