630C

Overview

The Hammond Manufacturing 630C is a pulse transformer designed for SCR and thyristor triggering applications. It features a 1:1 turns ratio and an inductance of 4 mH with a DC resistance of 0.86 ohms. The component utilizes through-hole mounting and measures 25.00 mm in length, 20.00 mm in width, and 13.00 mm in height. This sealed unit is part of the 630 series and complies with RoHS3 standards.

Feature Summary

• Sealed construction for reliable operation
• Optimized for SCR and thyristor gate triggering
• Through-hole mounting configuration

Applications

• SCR trigger circuits
• Thyristor firing systems
• Pulse isolation interfaces

Procurement Notes

Verify that the replacement component matches the original electrical specifications, specifically the 4 mH inductance and 0.86 ohm DC resistance. Confirm physical dimensions are compatible with existing PCB layouts. Ensure the substitute maintains the same sealing characteristics and mounting style to guarantee proper integration into the assembly.

Selection Notes

Select this component for applications requiring isolated pulse transmission to control gates. The 1:1 ratio provides direct signal transfer without voltage transformation. Consider the sealed design for environments where moisture or dust protection is necessary for the transformer element.

Part Context

This part belongs to the 630 series of pulse transformers from Hammond Manufacturing. These components are engineered specifically for high-speed switching applications involving silicon-controlled rectifiers. The series offers standardized dimensions for easy integration into industrial control panels.
