ERJ-1TYJ102U – PANASONIC

Overview

The Panasonic ERJ-1TYJ102U is a robust 1 kΩ, 5% tolerance thick-film chip resistor designed for demanding applications, capable of dissipating up to 1 Watt. Its 2512 (6332 Metric) package offers a significant thermal mass, crucial for managing power dissipation in high-current circuits. A key design consideration for this component is the trade-off between its high power rating and its ±200ppm/°C temperature coefficient; while it handles significant power, careful thermal management is still required to maintain precise resistance values in environments with wide temperature fluctuations.
