Additional Details:

ERA3YEB122V resistors are manufactured using thin film technology, providing excellent precision and stability. A thin layer of resistive material is deposited on a ceramic substrate, and the resistance value is trimmed using laser trimming. The resistor is protected with a passivation layer and coated with solderable terminations for easy PCB mounting. The ERA series offers a wide range of resistance values and tolerances to suit different application needs. They are designed to withstand harsh environmental conditions and provide low noise performance, making them suitable for sensitive analog circuits.
