148Y

Overview

The Hammond Manufacturing 148Y is an audio and signal transformer designed for open-frame printed circuit board mounting. It features a single channel configuration with pin terminal connections and through-hole termination. The component operates within a frequency range of 200 Hz to 15 kHz. Electrical specifications include a primary coil impedance of 20,000 ohms and a secondary coil impedance of 1,000 ohms. The primary resistance is documented at 410 ohms. Physical dimensions are 0.82 inches in length, 0.68 inches in width, and 0.69 inches in height.

Feature Summary

• Open-frame construction suitable for direct printed circuit board integration
• Single-channel design optimized for driver applications
• Through-hole pin terminal connection method for secure mounting

Applications

• Audio signal processing circuits
• Driver stage interfacing in electronic systems
• Signal transformation in low-frequency audio equipment

Procurement Notes

Verify the specific datasheet version to confirm exact resistance values, as documentation may list primary resistance at 410 ohms or 2.23 kohms depending on the revision. Ensure the through-hole footprint matches the target PCB layout. Confirm RoHS compliance status directly from the manufacturer's current product specification sheet before finalizing procurement orders.

Selection Notes

Select this component when a single-channel audio transformer with high primary impedance is required for board-level assembly. The open-frame design allows for flexible mechanical integration but requires consideration of electromagnetic interference shielding if used in sensitive environments. Verify that the operating frequency range aligns with the specific application requirements.

Part Context

This part belongs to the Hammond Manufacturing 148 series of audio transformers. The series includes variants such as the 148R, which shares similar architectural characteristics but differs in specific impedance ratios. These components are categorized under audio and signal transformers, distinct from electrical enclosures or wire management products also offered by the manufacturer.
