104M48QH39

Overview

The 104M48QH39 is an arc suppressor and snubber network manufactured by Cornell Dubilier Knowles. It integrates a 0.1 µF capacitor with a 39 Ω resistor in a single axial-leaded package. The unit is rated for 1200 VDC and 480 VAC, with a power dissipation capacity of 2 W. Physical dimensions are 40.6 mm in length, 16.3 mm in width, and 26 mm in height.

Feature Summary

• Integrated RC snubber network combining capacitance and resistance
• High voltage rating suitable for industrial AC/DC environments
• Axial leaded construction for through-hole mounting

Applications

• Arc suppression in high-voltage circuits
• Snubber networks for switching applications
• Industrial power electronics protection

Procurement Notes

Verify the specific part number 104M48QH39 against official Cornell Dubilier Knowles documentation to confirm the integrated RC values and voltage ratings. Ensure the axial lead configuration matches the target PCB layout requirements before procurement.

Selection Notes

Select this component when a combined snubber solution is required for high-voltage isolation. The integrated design simplifies assembly compared to discrete components. Confirm that the 2W power rating and 1200VDC withstand capability meet the circuit's peak transient and steady-state demands.

Part Context

This component belongs to the Cornell Dubilier Electronics (CDE) line of specialized passive networks. CDE, now part of Knowles Corporation, focuses on robust capacitor solutions for demanding industrial and power applications. This specific model serves as a dedicated protection device rather than a standard standalone capacitor.

Replacement Considerations

Publicly confirmed substitute part numbers for the 104M48QH39 are not available in the provided source data. Verify compatibility with any alternative RC networks by matching the 0.1 µF capacitance, 39 Ω resistance, and 1200 VDC voltage rating.
