Overview
The DKG1553-75 is a ruggedized audio and signal transformer manufactured by iNRCORE, LLC. It functions as an interface transformer designed for MIL-STD-1553 applications with surface mount (SMD/SMT) termination. The component operates within a frequency range of 75 kHz to 1 MHz and supports two channels. It features a maximum DC resistance of 3.5 Ohms and exhibits humidity sensitivity. The physical dimensions are 17.15 mm in length, 10.16 mm in width, and 4.7 mm in height. The device is rated for operation between -55°C and +125°C.
Feature Summary
- Ruggedized construction suitable for demanding environments
- Dual-channel configuration for interface applications
- Surface mount termination for automated assembly
Applications
- MIL-STD-1553 bus interface systems
- Audio signal transmission circuits
- General signal transformation interfaces
Procurement Notes
Verify the specific datasheet version and manufacturing date code upon order confirmation. Confirm that the supplied units match the exact DKG1553-75 designation, as suffix variations may indicate different winding ratios or packaging types. Ensure handling procedures account for the stated humidity sensitivity classification during storage and reflow processes.
Selection Notes
Select this component when a dual-channel, ruggedized pulse transformer is required for MIL-STD-1553 compliant designs. The SMD package facilitates board space optimization compared to through-hole alternatives. Verify that the 75 kHz to 1 MHz frequency range aligns with the system's signal requirements and that the thermal rating meets the operational environment constraints.
Part Context
This part belongs to the iNRCORE DKG series of MIL-STD-1553 transformers. Variants such as DKG1553-62 and DKG1553-45 exist within the same product line, typically differing in winding ratios or specific electrical characteristics while maintaining similar form factors and ruggedized design principles for military and aerospace data bus applications.
Replacement Considerations
Cross-reference with other DKG series variants like DKG1553-62 if winding ratio adjustments are permissible. Direct substitution requires verifying identical pinout compatibility and ensuring the alternative model meets the same MIL-STD-1553 interface specifications and thermal ratings.
