Minimize Package Design with...
The World’s Smallest 1553 Isolation Transformers!

The new ULP series 1553 isolation transformers are the world’s smallest single channel isolation devices, providing a 46% smaller size with 32% less weight than what was previously available. This achievement enables LRU box manufacturers to fit these isolation transformers near edge connectors for more efficient data transmission and package design. 

Electrical performance meets or exceeds all DDC and industry requirements at operating temperatures between -55°C and +130°C. The new SMD transformers are a leadless design and are available in RoHS versions.  All ULP transformers are available in Tape and Reel packaging and can be ordered immediately from DDC.

Features include:

  • Smallest Footprint Available

  • Low Profile

  • Surface Mount - Tape and Reel Available
  • Withstands Conventional IR/Convection Reflow Process
  • -55°C to +130°C Operating Temperature Range
  • Built and Tested to MIL-PRF-21038 and MIL-STD-202
  • Available RoHS Compliant

Optimize System Connectivity with...
The World’s Smallest 1553 In-Line Couplers!

The new DBM series data bus couplers utilize the world’s smallest coupler housing body, at 1.1” (27.9 mm) long by 0.31” (7.9 mm) high, enabling more compact packaging with greater flexibility options for integrating harness assemblies with LRU’s on the aircraft, providing optimized system connectivity.

These couplers are available in one, two, three and four stub designs and can be ordered with internal termination as an option. Standard versions of the couplers include 12” of MIL-C-17 lead wire on all bus and stub configurations.  Electrical performance meets or exceeds all DDC and industry requirements at operating temperatures between -55°C and +130°C.  All isolation resistors are 1W and isolation transformers meet MIL-PRF-21038 requirements. Customer designs are available including additional stub/bus configurations and custom connectors.

Features include:

  • Flight Qualified

  • Small & Lightweight

  • 100% Tested
  • Can be Supplied as a Complete Harness According to Customer Specification
  • -55°C to +130°C Operating Temperature Range
  • 1 Watt Resistors
  • Single or Multi-Stub
