The Ohmite OD121KE is a carbon composition resistor that offers a resistance of 120 ohms with a ±10% tolerance, making it a solid choice for applications that require stability yet allow for some variation. Not only does it have a power rating of 0.25W (1/4 Watt), but it also supports a maximum operating voltage of 250V, ensuring it can handle moderate electrical loads. Moreover, because it features an axial lead mounting style, it is particularly well-suited for through-hole applications, which enhances its durability in circuits. In addition, this resistor boasts pulse-withstanding capabilities, making it more resistant to sudden voltage spikes, a crucial factor in high-reliability designs.

Even though the OD121KE remains a respected component in legacy designs, engineers must nevertheless consider its operating temperature range of -70°C to +130°C, especially when working in extreme environments. Furthermore, its carbon composition construction contributes to its ability to absorb pulses effectively, yet at the same time, this material is known for drifting in resistance over time. Consequently, this may pose challenges in applications where long-term precision is required.
