EXB-U18621JX

EXB-U18621JX Description

The EXB-U18621JX by Panasonic Electronic Components is a high-performance 4-resistor array designed for precision surface-mount applications. With a compact 0502 (1406 Metric) convex package featuring long-side terminals, this device offers a 620Ω resistance per element at ±5% tolerance and a ±200ppm/°C temperature coefficient. Its ultra-low profile (0.018" seated height) and miniature footprint (1.40mm x 0.60mm) make it ideal for space-constrained PCB designs. The array operates at 31mW power per element and is isolated-circuit configured, ensuring reliable performance in diverse electronic systems. Compliant with ROHS3 and REACH standards, it is delivered in tape-and-reel (TR) packaging for automated assembly efficiency.

EXB-U18621JX Features

• Compact Design: 0502 package with convex, long-side terminals for robust solder joints.
• Stable Performance: ±200ppm/°C temperature coefficient ensures minimal resistance drift.
• High Reliability: MSL 1 (Unlimited) moisture sensitivity and RoHS3/REACH compliance for environmental resilience.
• Optimized Power Handling: 31mW per resistor balances current load and thermal management.
• Automation-Ready: Tape-and-reel packaging streamlines high-volume PCB assembly.

EXB-U18621JX Applications

This resistor array excels in:

• Consumer Electronics: Voltage division in wearables, smartphones, and IoT devices due to its miniaturized form factor.
• Industrial Controls: Signal conditioning in sensors and PLCs, leveraging its stable ±200ppm/°C tolerance.
• Automotive Systems: ECU and infotainment circuits requiring AEC-Q200-qualified alternatives (though verification is recommended).
• Medical Devices: Low-profile, high-density PCBs where space and reliability are critical.

Conclusion of EXB-U18621JX

The EXB-U18621JX stands out for its precision, compactness, and industrial-grade robustness, making it a superior choice over bulkier or less stable resistor networks. Its isolated-circuit design and Panasonic’s manufacturing quality ensure consistent performance in high-density and temperature-variable environments. Ideal for modern electronics demanding miniaturization without compromising reliability, this array is a versatile solution for both prototyping and mass production.
