162D10

Overview

The Hammond Manufacturing 162D10 is a low-voltage power transformer designed for PCB mounting. It features dual primary windings rated for 115 VAC and 230 VAC input voltages. The secondary output provides 10 VAC center-tapped configuration with a current rating of 110 mA, resulting in a total power capacity of 1.1 VA. Constructed with a laminated core, this component utilizes through-hole termination for secure board attachment. Its low-profile physical design facilitates integration into compact electronic assemblies requiring isolated AC power conversion.

Feature Summary

• Dual primary winding capability supports operation at both 115 VAC and 230 VAC line frequencies
• Low-profile construction optimized for space-constrained printed circuit board applications
• Center-tapped secondary output enables split-rail or full-wave rectification circuits

Applications

• Low-power consumer electronics requiring isolated AC supply
• Control circuitry in industrial equipment panels
• Audio amplifier power stages utilizing center-tapped transformers

Procurement Notes

Verify the specific secondary voltage configuration matches the target application requirements before procurement. Confirm that the 1.1 VA power rating adequately supports the load current demands during peak operation. Ensure the through-hole pin spacing aligns with the designated footprint on the printed circuit board to prevent mechanical installation issues.

Selection Notes

Select this model when a compact, low-power transformer is required for dual-voltage primary operation. Consider the 1.1 VA limit to ensure it meets the energy needs of the downstream circuitry without excessive heat generation. Evaluate the physical dimensions against available board space, as the low-profile design is critical for enclosures with strict height restrictions.

Part Context

This component belongs to the Hammond 162 series of power transformers, which are characterized by their robust laminated core construction and versatile mounting options. The series offers various power ratings and voltage configurations to suit different electronic design needs. The 162D10 specifically addresses applications demanding low voltage outputs with high reliability and compliance with standard safety regulations.

Replacement Considerations

Direct substitutes within the same series include the 162D12, which shares identical physical dimensions and mounting style but provides a 12.6 VAC center-tapped secondary output instead of 10 VAC. Designers must verify that the alternative voltage rating does not exceed the maximum input specifications of the connected load components.
