835

Overview

The Hammond Manufacturing 835A is an audio and signal transformer designed for broadcast interstage applications. It features a 1:1 turns ratio and operates within a frequency range of 50 Hz to 15 kHz. The component provides shielding to minimize interference. Primary coil impedance options include 10 kOhms and 40 kOhms, with matching secondary coil impedance configurations available. Physical dimensions are 44.5 mm in length, 31.8 mm in width, and 65 mm in height. The unit weighs approximately 235.868 grams.

Feature Summary

• Designed for broadcast interstage audio signal transmission
• Provides electromagnetic shielding for noise reduction
• Offers flexible impedance matching via primary and secondary coil options

Applications

• Broadcast audio equipment interstage coupling
• Signal processing circuits requiring 1:1 isolation
• Audio engineering systems utilizing specific impedance levels

Procurement Notes

Verify the exact part number suffix, as the base model 835 may be discontinued or superseded by the 800A series. Confirm that the required impedance configuration (10 kOhms or 40 kOhms) matches the specific variant available from authorized distributors. Ensure compatibility with existing chassis mounting requirements given the fixed physical dimensions.

Selection Notes

Select this component when a shielded interstage transformer with a 1:1 ratio is required for broadcast-grade audio applications. Consider the available impedance options to match circuit requirements. Evaluate the physical size constraints against the specified dimensions of 44.5 mm x 31.8 mm x 65 mm. Verify availability through official channels due to potential discontinuation status of the base model.

Part Context

The 835A belongs to the Hammond Manufacturing 800 series of audio transformers. This series is specialized for professional audio and broadcast environments where signal integrity and impedance matching are critical. The product line focuses on providing reliable interstage coupling solutions with robust shielding characteristics suitable for demanding acoustic applications.

Replacement Considerations

Public documentation indicates the 835 has been discontinued as a stocked part. The 800A Series is identified as the replacement family. Verify if specific 800A variants meet the original 1:1 ratio and impedance requirements before substitution.
