77083181 Description

The 77083181 from CTS Resistor Products (a division of CTS Corporation) is a 4-resistor network designed for precision through-hole applications. This obsolete but REACH-unaffected component features isolated resistors with a 180Ω resistance, ±2% tolerance, and a ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Encased in an 8-pin SIP package with dimensions of 0.800" x 0.098" (20.32mm x 2.50mm), it offers a compact footprint while delivering 100mW power per element. Its ROHS3 compliance and non-MSLA (Not Applicable) moisture sensitivity make it suitable for legacy or low-risk environmental designs.

77083181 Features

• High Density: Four isolated 180Ω resistors in a space-saving SIP-8 package.
• Stable Performance: Low ±100ppm/°C thermal drift ensures reliability in temperature-fluctuating environments.
• Precision Tolerance: ±2% resistance accuracy for consistent circuit behavior.
• Robust Construction: Through-hole mounting for mechanical durability in harsh conditions.
• Compliance: Meets ROHS3 and REACH standards, with EAR99 and HTSUS 8533.21.0050 classifications for global compatibility.

77083181 Applications

Ideal for analog signal conditioning, voltage division, and pull-up/pull-down networks in legacy or industrial systems. Its isolated circuit design suits:

• Industrial Control PCBs requiring stable resistor networks.
• Test & Measurement Equipment where precision and thermal stability are critical.
• Retrofit or Repair of older electronics due to through-hole compatibility.
• Power Supply Circuits leveraging its 100mW power handling per element.

Conclusion of 77083181

While marked obsolete, the 77083181 remains a reliable choice for designers needing a compact, precision resistor network with proven thermal and electrical stability. Its through-hole SIP package, isolated resistors, and compliance with modern environmental standards make it a viable option for niche or legacy applications where newer SMD alternatives are impractical. For systems demanding tight tolerance and durability, this CTS Resistor Products array delivers consistent performance.
