77083333 Description

The 77083333 from CTS Resistor Products (a division of CTS Corporation) is a 4-resistor network designed for precision through-hole applications. This obsolete but still relevant component features 33kΩ resistance per element with a tight ±2% tolerance, ensuring reliable performance in analog and digital circuits. Encased in an 8-pin SIP (Single In-line Package), it measures 0.800" x 0.098" (20.32mm x 2.50mm) with a seated height of 0.195" (4.95mm), making it suitable for space-constrained designs. The isolated circuit type allows independent resistor operation, while its ±100ppm/°C temperature coefficient ensures stability across varying thermal conditions.

77083333 Features

• High Precision: ±2% tolerance and 33kΩ resistance for consistent signal conditioning.
• Robust Construction: Through-hole mounting with 100mW power per element, ideal for moderate-load applications.
• Thermal Stability: Low ±100ppm/°C drift minimizes resistance variance under temperature fluctuations.
• Compliance: ROHS3 Compliant and REACH Unaffected, meeting environmental standards.
• Non-MSIL: Not Applicable moisture sensitivity simplifies handling and storage.
• Bulk Packaging: Cost-effective for volume production or prototyping.

77083333 Applications

This resistor network excels in:

• Analog Signal Processing: Voltage dividers, feedback networks, and sensor interfaces in industrial controls.
• Digital Circuitry: Pull-up/pull-down resistor arrays for microcontrollers and logic circuits.
• Legacy Systems: Maintenance or repair of older electronics where through-hole components are preferred.
• Test Equipment: Calibration and reference circuits due to its stable tolerance and isolation.

Conclusion of 77083333

While marked obsolete, the 77083333 remains a dependable choice for engineers needing high-density, isolated resistors in through-hole designs. Its low thermal drift, precise tolerance, and rugged SIP package make it suitable for both legacy upgrades and niche new designs. For applications demanding stable, low-power resistor networks, this CTS offering balances performance with ease of integration.
