Overview
The Hammond Manufacturing 107B is a miniature epoxy potted audio transformer designed for printed circuit board mounting. It features a primary impedance of 600CT ohms and a secondary impedance of 600CT ohms, providing a 1:1 turns ratio. The component operates within a frequency range of 300Hz to 50kHz with a response tolerance of ±1.5dB. Electrical characteristics include a maximum power level of 150mW and an isolation voltage of 100VRMS. Physical dimensions are 0.630 inches in length, 0.586 inches in width, and 0.630 inches in height.
Feature Summary
- Miniature epoxy potted construction for durability
- Printed circuit board pin-type mounting
- Suitable for audio input, line matching, and output applications
Applications
- Push-pull tube output circuits
- Hi-fi audio systems
- General-purpose audio signal transformation
Procurement Notes
Verify the specific datasheet version and manufacturer documentation to confirm electrical tolerances and physical dimensions before integration. Ensure compatibility with standard PCB pin spacing and soldering thermal profiles. Cross-reference the part number against official Hammond Manufacturing catalogs to distinguish between variants within the 107 series that may share similar nomenclature but differ in impedance or pin configuration.
Selection Notes
Select this component when a 1:1 impedance matching ratio is required for low-power audio signals up to 150mW. The 600CT to 600CT configuration is ideal for balanced line applications. Consider the compact molded case size for space-constrained designs. Verify that the operating frequency range of 300Hz to 50kHz meets the specific bandwidth requirements of the target audio application.
Part Context
The 107B belongs to the Hammond 107 Series of miniature audio transformers. This series is characterized by epoxy potting and PC board mount capabilities. It serves as a specialized solution for audio engineering tasks requiring precise impedance matching and signal isolation in compact form factors, distinct from larger chassis-mounted or general-purpose industrial transformers.
Replacement Considerations
Consult the official Hammond Manufacturing cross-reference list for direct equivalents within the 107 series. Verify that any substitute maintains the 600CT primary/secondary impedance and 1:1 ratio. Ensure the replacement also supports PC board mounting and meets the same frequency and power specifications.
