4309R-101-273

4309R-101-273 Description

The 4309R-101-273 from Bourns Inc. is an 8-resistor bussed network housed in a compact 9-pin SIP (Single In-Line Package). Designed for through-hole mounting, it offers a resistance value of 27kΩ per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across varying thermal conditions. The network operates at 200mW power per resistor and features a 50ppm/°C resistor-ratio drift, making it suitable for precision applications. Its 0.884" × 0.085" (22.45mm × 2.16mm) footprint and 0.195" (4.95mm) height enable space-efficient PCB designs.

4309R-101-273 Features

• High Reliability: REACH-compliant and EAR99/ECCN-certified for global compliance.
• Robust Construction: Non-MSLA (Moisture Sensitivity Level Not Applicable) ensures resilience in humid environments.
• Precision Performance: Low TCR (±100ppm/°C) and tight tolerance (±2%) minimize signal drift.
• Optimized Layout: Bussed circuit configuration simplifies design integration.
• Durable Packaging: Supplied in tubes for safe handling and storage.

4309R-101-273 Applications

Ideal for analog signal conditioning, voltage division, and pull-up/pull-down networks in:

• Industrial Controls: PLCs, sensor interfaces.
• Consumer Electronics: Audio equipment, display drivers.
• Telecom Infrastructure: Signal filtering, impedance matching.
• Automotive Systems: ECU signal processing (non-safety-critical).
