EXB-H8E473J

EXB-H8E473J Description

The EXB-H8E473J from Panasonic Electronic Components is a high-density 7-resistor bussed network designed for surface-mount applications. This obsolete but historically reliable component features a compact 8-SSIP (Single In-Line Package) with dimensions of 0.429" x 0.087" (10.89mm x 2.20mm) and a low-profile height of 0.106" (2.69mm), making it suitable for space-constrained PCB designs. Each resistor in the array offers a 47kΩ resistance with a ±5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The 62.5mW power rating per element and bussed circuit topology simplify circuit design by reducing component count and board footprint.

EXB-H8E473J Features

• Compact SSIP Package: Ideal for high-density layouts with minimal board space.
• Bussed Network Configuration: Simplifies routing and reduces parasitic effects.
• Wide Operating Range: Stable performance with ±200ppm/°C thermal stability.
• Low Moisture Sensitivity (MSL 1): Suitable for extended storage and standard assembly processes.
• RoHS-Compliant (ECCN EAR99): Meets global environmental and trade regulations.
• Cut Tape Packaging (CT): Facilitates automated pick-and-place assembly.

Compared to discrete resistors, the EXB-H8E473J reduces placement time and improves consistency in voltage divider, pull-up/pull-down, and termination circuits. Its obsolete status may limit new designs but remains valuable for legacy system maintenance or replacements.

EXB-H8E473J Applications

• Consumer Electronics: Used in LCD backlighting, keypad interfaces, and power management circuits.
• Industrial Controls: Reliable for sensor signal conditioning and PLC I/O modules.
• Automotive Systems: Suitable for non-critical ECU circuits (e.g., lighting, infotainment).
• Telecom Hardware: Efficient in line termination and impedance matching networks.

Conclusion of EXB-H8E473J

The EXB-H8E473J resistor network excels in space-saving, repeatable performance, and ease of integration, though its obsolete status necessitates alternative solutions for new designs. Its 47kΩ bussed array remains a cost-effective choice for legacy repairs or bulk purchases. Engineers should verify compatibility with modern alternatives like Panasonic’s EXB-V8 series for active projects.
