Description
A 390K ohm resistor with a 1/4 watt power rating and ±5% tolerance is a commonly used component in electronic circuits. Resistors are essential for managing current flow, setting voltage levels, and dividing voltages. The resistance value of 390,000 ohms (390K) indicates a significant level of resistance to current flow. The 1/4 watt rating specifies the maximum power it can dissipate safely, while the ±5% tolerance indicates the acceptable range of variation from its nominal resistance value. These resistors are color-coded for easy identification.
Features:
Resistance Value: 390K ohms (390,000 ohms).Power Rating: 1/4 watt (0.25W).
Tolerance: ±5% (acceptable range from 370.5K ohms to 409.5K ohms).
Material: Typically made from carbon film, metal film, or metal oxide film.
Temperature Coefficient: Specifies the change in resistance with temperature, typically in ppm/°C.
Packaging: Available in through-hole (axial lead) or surface-mount (SMD) formats.
Reliability: Designed to provide consistent performance over a wide range of environmental conditions.
Color Code: Resistors use a color code to indicate their resistance value, tolerance, and sometimes temperature coefficient. The color bands on a 390K ohm resistor with ±5% tolerance are as follows:
First Band (3): Orange
Second Band (9): White
Third Band (4 zeros): Yellow
Tolerance Band (±5%): Gold
Application:
These resistor values are in the kilohm range and are often used in electronic circuits requiring higher resistance values, such as voltage dividers, biasing networks, and precision applications. The color codes provided help identify each resistor's resistance values and tolerance levels, making it easier to select the appropriate one for a specific circuit design.Technical Details
