Overview
The Hammond Manufacturing 148Q-BULK is an open-frame audio signal transformer designed for printed circuit board mounting. It features a single channel configuration with a primary coil impedance of 1700 ohms and a secondary coil impedance of 238 ohms. The device operates within a frequency range of 20 Hz to 20 kHz, suitable for standard audio applications. Constructed as a pin terminal component with through-hole termination, it provides electrical isolation between driver stages in audio circuits.
Feature Summary
- Open-frame construction facilitates direct integration into custom audio circuit boards
- Single-channel design supports driver stage coupling requirements
- Through-hole pin terminals ensure secure mechanical attachment during assembly
Applications
- Audio amplifier driver stage coupling
- Signal transformation in professional audio equipment
- Custom audio interface circuit designs
Procurement Notes
Verify the specific suffix or bulk packaging designation against the manufacturer's current datasheet to confirm exact physical dimensions and lead times. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the Mouser part number 546-148Q-BULK with official Hammond documentation to validate availability status and any recent manufacturing updates before finalizing procurement plans.
Selection Notes
Select this transformer when a 1700:238 ohm impedance ratio is required for audio driver applications. Confirm that the through-hole package style aligns with your PCB layout constraints. Evaluate the operating frequency range against your specific audio bandwidth needs. Ensure the open-frame design does not conflict with thermal management or shielding requirements of the final enclosure.
Part Context
This component belongs to the Hammond Manufacturing 148 series of audio transformers. These devices are engineered for robust performance in analog audio signal paths. The series typically offers various impedance ratios to match different source and load characteristics. The 148Q variant specifically targets applications requiring precise impedance matching between amplifier stages.
Replacement Considerations
Consult Hammond Manufacturing cross-reference tools for parametrically similar parts. Verify that substitute components maintain the same 1700:238 ohm ratio and through-hole footprint. Ensure replacement units meet identical frequency response specifications and power handling capabilities.
