77081474 Description

The 77081474 from CTS Resistor Products (a division of CTS Corporation) is a 7-resistor bussed network designed for through-hole mounting, offering a compact and reliable solution for circuit designs requiring multiple resistors in a single package. This obsolete but still relevant component features a 470k Ohm resistance per element with a tight ±2% tolerance, ensuring consistent performance in precision applications. Its ±100ppm/°C temperature coefficient provides stable operation across varying thermal conditions, while the 100mW power rating per element balances efficiency and durability. Encased in an 8-pin SIP (Single In-line Package) with dimensions of 0.800" x 0.098" (20.32mm x 2.50mm) and a seated height of 0.195" (4.95mm), it is ideal for space-constrained layouts.

77081474 Features

• Bussed Circuit Configuration: Simplifies PCB layout by connecting resistors in a common-node arrangement, reducing wiring complexity.
• High Resistance Value: 470k Ohm resistors cater to high-impedance applications like signal conditioning or pull-up/pull-down networks.
• Robust Construction: Through-hole design ensures mechanical stability, suitable for industrial environments.
• Compliance: ROHS3 Compliant and REACH Unaffected, meeting environmental regulations.
• Wide Operating Range: Not Applicable MSL rating allows storage without moisture sensitivity concerns.

77081474 Applications

This resistor network excels in:

• Analog Signal Processing: Voltage dividers, filter networks, and impedance matching in audio/telecom systems.
• Industrial Control Systems: PLCs, sensor interfaces, and legacy equipment maintenance due to its through-hole reliability.
• Test & Measurement Equipment: Calibration circuits and reference networks requiring stable resistance values.
• Consumer Electronics: Power management and bias circuits in older or specialized devices.

Conclusion of 77081474

While marked obsolete, the 77081474 remains a viable choice for designers seeking a high-resistance, compact, and robust resistor network. Its bussed architecture, tight tolerance, and through-hole durability make it particularly suited for legacy systems, industrial applications, and precision analog circuits. For projects prioritizing ease of integration and consistent performance, this CTS Resistor Products array offers a dependable solution despite its discontinued status.
