Overview
The Hammond Manufacturing 140P is an audio signal transformer designed for signal level applications. It features a screw end termination type and operates within a frequency range of 70 Hz to 11 kHz. The primary coil impedance is 4 Ohms, while the secondary coil impedance is 60 kOhms. This component belongs to the 140 series and is unshielded. The physical height of the unit is 25.4 mm (1 inch).
Feature Summary
- Designed specifically for signal level audio applications.
- Utilizes screw-type end terminations for connection.
- Operates with a wide frequency response from 70 Hz to 11 kHz.
Applications
- Audio signal processing circuits
- Impedance matching in audio systems
Procurement Notes
Verify the specific manufacturer part number against official Hammond Manufacturing documentation to ensure accuracy. Confirm that the required impedance values and frequency range align with the system design requirements. Check for any specific mounting or environmental constraints associated with the unshielded construction before finalizing procurement.
Selection Notes
Select this component when a dedicated audio signal transformer with a 4 Ohm primary and 60 kOhm secondary impedance is required. Ensure the application environment does not demand shielding, as this model is unshielded. Verify that the operating frequency falls within the specified 70 Hz to 11 kHz range for optimal performance.
Part Context
The 140P is part of the Hammond Manufacturing 140 series of audio transformers. This series focuses on providing reliable signal transformation for audio equipment. The component serves as a passive interface between different stages of an audio circuit, facilitating impedance matching and signal transfer without active amplification.
