Through Hole Resistors are widely used across a variety of applications to reduce, divert, or control current in electrical circuits. The OM1205E-R58 is a through-hole resistor that is specially developed for in-circuit measurement and fault finding in printed circuit boards.

The OM1205E-R58 features a wide resistance range, from 1mOhm to 500mOhm, and a very low current of up to 10 mA. Its mechanical construction uses the standard 5-band (or 5-ring) through-hole structure, which is designed to allow for quick identification of major and minor resistance values. It has a very low temperature coefficient of resistance (TCR) of approximately 0.1%, making it well-suited for precision applications.

The OM1205E-R58 is a standard voltage rating and operating temperature rating of up to 85°C. It is also available in both axial and radial packaging. The resistor\'s low series resistance and low voltage drop make it suitable for both switched-mode power supplies and high-side current sense applications. It is also compatible with surface mount technology (SMT) and surface mount soldering (SMD).

The OM1205E-R58 offers superior performance due to its high resistance-to-voltage ratio and low power dissipation. It is also highly reliable with very low leakage current, meaning that current is not drawn from the circuit, even when high levels of wattage are applied. This is especially beneficial since it reduces the risk of sparking or arcing, which can damage components in the circuit.

At the core of its design, the OM1205E-R58 consists of a resistive element only. This element is made of a blend of materials consisting of carbon, quartz, and metal oxides. This combination of materials enables the resistor to have a high maximum voltage rating and low thermal resistance. Additionally, the element is encapsulated in a ceramic casing that provides protection against mechanical and environmental damage.

The OM1205E-R58 is a reliable and efficient resistor that is suitable for many different applications. It can be used as a current limiting device in high voltage transformers, as a feedback resistance in power supply circuits, and for sensing current in power semiconductor devices. Its excellent temperature coefficient makes it an ideal choice for precision measurement and fault finding. Despite its accuracy, it is still inexpensive compared to other types of resistors.

In summary, the OM1205E-R58 is a through-hole resistor that offers excellent performance in a range of applications. Its low cost, low thermal resistance, and low voltage rating make it a great choice for current limiting, feedback resistance, and sensing current in power semiconductor devices. It also offers very low leakage current and excellent temperature coefficient, making it a reliable and efficient option for fault finding and precision measurement.
