Additional Details:

The TMCHC1E475KTRF features a resistance value of 4.7 Megaohms (4,700,000 ohms). The 'K' in the part number indicates a tolerance of ±10%. The 'TRF' suffix typically denotes tape and reel packaging for automated assembly. The power rating and voltage rating should be checked in the specific Vishay datasheet for this part. These resistors are commonly used in applications where high resistance values are needed, such as in high-impedance circuits, sensing circuits, and feedback networks. They are designed to withstand typical soldering processes used in electronics manufacturing. The temperature coefficient of resistance (TCR) is also an important parameter to consider in applications where temperature stability is critical. Always refer to the Vishay datasheet for the most accurate and up-to-date specifications.
