560C

Overview

The Hammond Manufacturing 560C is a broadcast-quality audio transformer designed for microphone or line-level applications. It features a 12/48 ohm primary impedance and a 150/600 ohm secondary impedance configuration. The unit is epoxy potted within a molded case to ensure durability and electromagnetic interference protection. Electrical performance includes a power rating of 150 mW with a tolerance of ±1.5 dB across a frequency range of 30 Hz to 30 kHz (or up to 50 kHz depending on specific documentation). It utilizes pin-type through-hole mounting with a minimum pin length requirement of 0.187 inches.

Feature Summary

Epoxy potted construction in a molded case for environmental protection
Designed for broadcast quality audio signal transmission
Pin-type printed circuit board mount for secure installation

Applications

Microphone to line level interfacing
Broadcast audio equipment integration
Signal impedance matching between 12/48 ohm and 150/600 ohm circuits

Procurement Notes

Verify the specific impedance configuration required for your circuit, as sources indicate variations such as 150/150 or 150/600 ohms. Confirm that the PCB layout accommodates the 0.187-inch minimum pin length for proper through-hole insertion. Ensure the application environment does not exceed the thermal limits associated with epoxy potting. Cross-reference the datasheet for exact frequency response curves if operating near the 30 kHz upper limit.

Selection Notes

Select this component when a robust, potted audio transformer is needed for professional broadcast or high-fidelity audio applications. The 12/48 ohm primary side is suitable for low-impedance microphones, while the secondary options support standard line-level inputs. Consider the physical dimensions and mounting style to ensure compatibility with the target chassis or PCB design. This model is appropriate where electromagnetic shielding provided by the potted case is necessary.
