77081202 Description

The 77081202 from CTS Resistor Products (a division of CTS Corporation) is a 7-resistor bussed network designed for through-hole mounting. This obsolete yet reliable component features a 2kΩ resistance per element with a tight ±2% tolerance, ensuring consistent performance in precision circuits. Its ±100ppm/°C temperature coefficient provides stability across varying environmental conditions, while the 100mW power rating per resistor balances compactness with durability. Encased in an 8-pin SIP package with dimensions of 20.32mm x 2.50mm (0.800" x 0.098") and a 4.95mm (0.195") seated height, it suits space-constrained layouts. The ROHS3-compliant, REACH-unaffected construction meets modern environmental standards, though its bulk packaging and obsolete status may require inventory planning.

77081202 Features

• 7-resistor bussed network simplifies circuit design by sharing a common node.
• 2kΩ resistance with ±2% tolerance for precision applications.
• ±100ppm/°C TCR ensures minimal resistance drift under thermal stress.
• 100mW power dissipation per element balances load handling and compactness.
• Through-hole 8-SIP package (20.32mm x 2.50mm) for robust mechanical mounting.
• ROHS3/REACH compliant for environmentally conscious designs.
• Not MSL-sensitive (MSL: Not Applicable), reducing handling constraints.
• Bulk packaging ideal for prototyping or small-batch production.

77081202 Applications

This resistor array excels in:

• Analog signal conditioning (e.g., voltage dividers, pull-up networks).
• Industrial control systems requiring stable, bussed resistance paths.
• Legacy equipment repairs due to its through-hole design and obsolete status.
• Power supply feedback circuits where low TCR minimizes calibration drift.
• Educational electronics kits benefiting from its straightforward bussed topology.

Conclusion of 77081202

The 77081202 offers a blend of precision, thermal stability, and compactness, making it a pragmatic choice for legacy or low-volume designs. While obsolete, its bussed architecture and through-hole reliability remain valuable for maintenance or niche applications. Engineers should evaluate alternatives for high-volume production but can leverage this part for prototyping or repairs where its ±2% tolerance and 100mW rating are critical. Its ROHS3 compliance ensures alignment with modern environmental mandates despite its discontinued status.
