Xcelite / Apex 99S821 Dual-In-Line Resistor Network
The Xcelite / Apex 99S821 is a dual-in-line thick film resistor network designed for applications requiring multiple, precisely matched resistor values in a compact form factor. These networks offer a wide resistance range from 10 Ohms to 10 MegOhms, with standard tolerances of ±2% (or optional ±1% for F tolerance). They operate reliably across a temperature range of -55°C to +125°C, exhibiting excellent temperature coefficient of resistance tracking. The 99S821 is suitable for use in circuits requiring pull-down resistors, TTL to ECL translation, and other applications where multiple resistance values are needed. It is RoHS compliant and features robust construction for long-term reliability in industrial environments.
