The CDAD family of high-speed differential delay lines are available in surface-mount (SMD) packaging in either standard or custom specification.
Features
- Miniaturized high-speed differential delay lines that combine ELMEC's high-density delay line elements in the same surface-mount package as the CDA family of single fixed SMD delay line.
- Suitable for use with a variety of logic elements including the ECLinPS, ECL 100KH, 10K series as well as TTL FAST, CMOS FACT and analog circuits.
- The CDAD family of differential delay lines are cased in the exact same package and footprint so that it can be inserted onto the CDA family land pattern.

ELMEC does not guarantee MSL Standards Classification. Please bake all components prior to reflow.
Baking Conditions: 120°C, 24 hours; or 80°C, 100 hours
However, because baking of T&R parts is not possible, transferring to trays is recommended prior to baking.
Non-RoHS-compliant components Maximum Reflow Cycles:1

1. Compliance Status
RoHS-compliant components are available. However, if RoHS-compliant components are not specified at the time of order, non-compliant stock items may be supplied until depleted.
Differentiating Compliant and Non-compliant Components
Compliant and Non-compliant Components will be differentiated by Lot Numbers.
Non-compliant Components: 2-digit year/month code
Compliant Components: S+2-digit year/month code (3-digit code)
Terminal Plating
Non-compliant Components: Base: 99% Ni/1% B, 1.2~1.6µm
External: 60% Sn/40% Pb, over 5µm
Compliant Components: Base: 100% Ni, 0.2~0.5µm
External: 100% Sn, 5~10µm
