Panasonic ERJ1GEF3903C Thick Film Chip Resistor

Panasonic's ERJ-1GEF3903C series of thick film chip resistors are engineered for demanding applications requiring high precision and reliability. These resistors utilize a metal glaze thick film resistive element and a three-layered electrode construction, ensuring robust performance. They are ideal for PCB size reduction and lightweight product designs, and their compatibility with automatic placement machines streamlines manufacturing processes. The resistors are available in various sizes (0402, 0603, 0805, 1206, 1210, 1812) and tolerances (±0.5%, ±1%), catering to a wide range of circuit requirements. They meet reference standards like IEC 60115-8 and JIS C 5201-8, ensuring quality and consistency.
