TO Headers are intended for high reliability miniature microcircuit applications. The single piece construction provides great strength and resistance to stress. The absence of sidewalls helps to facilitate circuit installation, as well as inspection and test accessibility. Our TO Headers are standard so they'll meet most any requirement.

We also stock a wide variety of TO-Cans (covers) for the TO Headers.

Features:
▪    High reliability
▪    Wide variety of sizes and Lead counts
