SIL09E472J

SIL09E472J Description

The SIL09E472J from TE Connectivity Passive Product is an 8-resistor bussed network array housed in a compact 9-pin SIP (Single In-Line Package). Designed for through-hole mounting, it features a 4.7kΩ resistance per element with a ±5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The array operates at 200mW power per element and adheres to ROHS3 compliance, making it suitable for modern electronics. Despite its obsolete status, it remains a reliable choice for legacy designs due to its robust construction and REACH unaffected compliance.

SIL09E472J Features

• High-Density Integration: Combines 8 resistors in a space-saving 0.900" x 0.098" (22.86mm x 2.50mm) footprint, ideal for PCB layouts with constrained real estate.
• Bussed Circuit Design: Simplifies circuit routing by connecting all resistors to a common node, reducing wiring complexity.
• Wide Operating Range: 200ppm/°C thermal stability ensures minimal resistance drift in industrial or automotive environments.
• Durability: MSL 1 (Unlimited) moisture sensitivity allows extended storage without degradation.
• Legacy Compatibility: Backward-compatible with older systems requiring through-hole mounting and bulk packaging.

SIL09E472J Applications

• Industrial Control Systems: Used in PLCs (Programmable Logic Controllers) for signal conditioning and pull-up/pull-down networks.
• Automotive Electronics: Employed in dashboard clusters and sensor interfaces due to its vibration-resistant through-hole design.
• Consumer Electronics: Ideal for CRT monitors, power supplies, and audio equipment requiring stable resistive networks.
• Test & Measurement Equipment: Provides precise voltage division and current limiting in calibration circuits.

Conclusion of SIL09E472J

The SIL09E472J offers a balance of compactness, reliability, and ease of integration, making it a pragmatic choice for legacy or cost-sensitive designs. While newer surface-mount alternatives exist, its through-hole robustness and bussed architecture ensure continued relevance in harsh environments. Engineers seeking a proven 4.7kΩ array with moderate precision will find this model a dependable solution.
