77061121 Description

The 77061121 from CTS Resistor Products (a division of CTS Corporation) is a 5-resistor bussed network designed for through-hole mounting, offering a compact and reliable solution for circuit design. This obsolete yet REACH-unaffected component features a 120Ω resistance per element with a tight ±2% tolerance, ensuring consistent performance in precision applications. Encased in a 6-pin SIP package with dimensions of 0.600" x 0.098" (15.24mm x 2.50mm) and a seated height of 0.195" (4.95mm), it balances space efficiency with robust construction. The ±100ppm/°C temperature coefficient and 100mW power rating per resistor make it suitable for stable, low-power circuits.

77061121 Features

• Bussed Circuit Configuration: Simplifies PCB layout by connecting resistors in a common-node arrangement, reducing wiring complexity.
• High Tolerance & Stability: ±2% tolerance and low TCR (±100ppm/°C) ensure reliable performance across temperature fluctuations.
• Compact SIP Package: Space-saving 6-pin design ideal for dense boards.
• RoHS3 Compliance: Meets environmental standards for lead-free manufacturing.
• Non-MSIL Rated: No moisture sensitivity concerns, suitable for standard handling environments.
