Additional Details:

The PCD0302MT3R3 is typically mounted using surface mount technology (SMT). It is available in tape and reel packaging for automated assembly. The resistor's power rating is typically around 1/20W (0.05W). The operating temperature range is typically -55°C to +155°C, allowing it to perform reliably in extreme conditions. Thin film resistors are manufactured by depositing a thin layer of resistive material onto a ceramic substrate, followed by precise trimming to achieve the desired resistance value. This process results in excellent uniformity and precision. The resistor's termination is typically made of nickel barrier with a solderable top coat.
