Chassis mounted audio equipment

Procurement Notes

Verify the specific part number suffix against official Hammond Manufacturing documentation to confirm impedance values and pinout configurations. Ensure compatibility with existing chassis mounting holes and wire lead lengths. Confirm RoHS compliance status if required for your assembly process. Cross-reference distributor datasheets with the manufacturer's official specification sheet to validate all electrical parameters before procurement.

Selection Notes

Select this component when a 100 CT primary to 3.2 ohm secondary audio transformer is required for chassis mounting. Consider the 700mW power rating and 150Hz-15kHz frequency range for suitability in audio signal paths. Compare physical dimensions against available panel space. Verify that the wire lead termination style meets circuit board or terminal block requirements.

Part Context

The 146D belongs to the Hammond 143-146 series of economy open-type audio transformers. These components are typically used in low-power audio circuits where cost-effective signal isolation or impedance matching is needed. The series offers various impedance combinations to suit different amplifier output stages.
