The Y1121100R000T9R is a 100R 250mW surface-mounting high precision Chip Resistor with standard lead (Pb)-free termination. The chip resistor utilizes Bulk Metal? foil moulded technology for the resistive element with its inherent low and predictable TCR and long term stability. This surface mountable product affords similar performance to the time tested S series moulded through-hole product.
