EXB-14V121JX

EXB-14V121JX Description

The EXB-14V121JX from Panasonic Electronic Components is a compact, surface-mount resistor network designed for high-density PCB applications. This 2-resistor isolated array features a 120Ω resistance per element with a ±5% tolerance, ensuring reliable performance in precision circuits. Encased in an ultra-thin 0302 (0805 Metric) convex package with long-side terminals, it offers a seated height of just 0.018" (0.45mm) and dimensions of 0.031" x 0.024" (0.80mm x 0.60mm), making it ideal for space-constrained designs. The device operates within a ±200ppm/°C temperature coefficient range, maintaining stability across varying environmental conditions.

EXB-14V121JX Features

• Miniaturized Design: 0302 package with convex, long-side terminals for efficient PCB space utilization.
• High Reliability: ROHS3 Compliant and REACH Unaffected, meeting stringent environmental standards.
• Low Power Dissipation: 31mW power rating per resistor, suitable for low-power applications.
• Stable Performance: ±200ppm/°C TCR ensures minimal resistance drift under thermal stress.
• Ease of Assembly: MSL 1 (Unlimited) moisture sensitivity allows extended floor life without baking.
• Automation-Friendly: Supplied in Tape & Reel (TR) packaging for streamlined pick-and-place processes.
