ON2015E-R58

Through Hole Resistors are indispensable components used in circuit boards all over the world. The ON2015E-R58, belonging to this resistor family, was released by Panasonic in 2010 and has become a popular choice amongst engineers. This article will provide a detailed overview of the application field and working principles of ON2015E-R58.

The ON2015E-R58 is a 5 watt rated power resistor, with an axial termination configuration. To facilitate its usage for different applications, the resistance value of this component can go from 0 Ω up to 10 kΩ, covering an extensive range of resistance specifications. It is also capable of withstanding a maximum operating voltage of 300 volts DC. Thanks to these features, the ON2015E-R58 can be used for many practical applications of a circuit board, from basic current limiter, voltage divider, load resistor to dynamic filter. Its temperature coefficient is also remarkable; it offers a maximum of ± 100 ppm /°C, allowing it to provide stable performances against different temperature variations.

The ON2015E-R58 is made of a thick ceramic substrate, with a winding of resistive wire on the resistance element. The substrate works as a heat conductor, whereas the winding acts as a resistance element. When electricity passes through this winding, its flow is hindered, in a controlled manner, by the resistive resistance of the wire. The total resistance of the component therefore changes according to the winding structure, allowing the user to assign it specific resistance value.

When it comes to assembly, the ON2015E-R58 is available in two different package configurations. The first one involves two leads soldered to the resistor’s terminals, thus allowing it to be directly installed to the circuit board. The second configuration consists of a single side tape and reel, making the unit suitable for automated insertion assembly. With regard to the actual installation process, the ON2015E-R58 requires no additional padding or special heat treatment; its intrinsic construction is already engineered to bear significant thermal shock.

Advantages of the ON2015E-R58 go beyond its remarkable tolerances and features; in fact, the device is relatively inexpensive, and its electrical and thermal parameters reliably meet the requirements of many systems. This is a significant aspect to consider, especially when the user is looking for high-performance, low-cost solutions. Furthermore, due to its thick ceramic substrate, the unit can also withstand pulse and surge loads in critical regulation systems, granting high level of reliability.

All in all, the ON2015E-R58 proves to be an efficient, reliable and cost-efficient Through Hole Resistor. Its application fields range from basic to industrial-level applications, where consistent performance, reliability and efficiency is key. As a consequence, it is a widely used resistor in almost all parts of the world.
