77083330

77083330 Description

The 77083330 from CTS Resistor Products (a division of CTS Corporation) is a 4-resistor network designed for precision through-hole applications. This obsolete yet reliable component features a 33Ω resistance per element with a tight ±2% tolerance, ensuring consistent performance in demanding circuits. Its isolated circuit type allows independent resistor operation, while the ±100ppm/°C temperature coefficient guarantees stability across varying thermal conditions. Encased in an 8-pin SIP package with dimensions of 0.800" x 0.098" (20.32mm x 2.50mm) and a 0.195" (4.95mm) seated height, it suits space-constrained layouts. Rated at 100mW power per element, it complies with ROHS3 and REACH environmental standards.

77083330 Features

• 4 isolated resistors in a compact 8SIP through-hole package.
• 33Ω resistance with ±2% tolerance for high precision.
• Low TCR (±100ppm/°C) ensures minimal resistance drift under temperature fluctuations.
• 100mW power rating per element balances performance and thermal management.
• Bulk packaging simplifies inventory handling for legacy or low-volume production.
• Not MSL-sensitive, eliminating moisture-related storage concerns.
• EAR99/ECCN classification facilitates global export compliance.

77083330 Applications

Ideal for analog signal conditioning, voltage division, and pull-up/down circuits in legacy or industrial systems. Its isolated design suits test equipment, medical devices, and telecom infrastructure where signal integrity is critical. The through-hole construction makes it a fit for prototyping or repairing older PCB designs. While obsolete, it remains valuable for long-lifecycle products requiring stable, low-noise resistor networks.

Conclusion of 77083330

The 77083330 offers a robust combination of precision, thermal stability, and isolation for specialized through-hole applications. Though discontinued, its ROHS3 compliance and 100ppm/°C TCR make it a dependable choice for legacy systems or replacements. Engineers seeking a 4-resistor array with 33Ω values will appreciate its balance of performance and simplicity in analog or mixed-signal designs.
