4416P-2-181 Description

The 4416P-2-181 from Bourns Inc. is a high-performance 15-resistor bussed network in a compact 16-pin SOIC package, designed for precision surface-mount applications. With a 180Ω resistance per element and a tight ±2% tolerance, this device ensures reliable signal conditioning and voltage division in dense PCB layouts. Its ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift provide stable performance across varying thermal conditions, making it ideal for environments requiring long-term stability. The 0.410" x 0.295" (10.41mm x 7.50mm) footprint and 2.90mm profile optimize space efficiency without compromising power handling (160mW per element).

4416P-2-181 Features

• Bussed Circuit Configuration: Simplifies design by connecting multiple resistors to a common node, reducing component count.
• Low TCR & Ratio Drift: Ensures minimal resistance variation under thermal stress, critical for precision analog circuits.
• MSL 1 (Unlimited): No baking required prior to reflow, streamlining assembly processes.
• Tape & Reel Packaging: Supports automated pick-and-place manufacturing for high-volume production.
• REACH/EAR99 Compliance: Meets environmental and export control standards for global deployment.

4416P-2-181 Applications

• Voltage Dividers: Used in ADC/DAC reference circuits for stable voltage scaling.
