mance. With our development teams, we are constantly working on individual innovations for our customers and respond to the constant changes in the markets, driven by ever-increasing environmental and performance requirements.
As part of a joined development process, we can respond to the wishes of our customers in detail and adapt applications flexibly based on customer-specific requirements.
We are constantly working to make our products lighter, smaller and more powerful. We are happy to incorporate our development expertise and product knowledge into our customers’ applications.
All components are extensively tested in our in-house laboratory. In this way, we ensure that our customers receive a high-quality product for their applications.
Continuous Improvement Process is the base for our high product quality. Every single production process is proven over the long history in manufacturing. Quality gates after every process step are mandatory to keep the high quality.
We offer automotive-compliant manufacturing, automated according to IATF 16949 certification, technologically demanding projects.
We produce and develop close to you: Miba has 30 production sites with 7500 employees worldwide.
State-of-the-art production lines
Miba produces resistors using state-of-the-art standards at its facilities in Kirchbach-Zerlach (Austria) and Dongguan (China). Both locations feature advanced automated manufacturing machines to ensure a seamless and efficient production process.
Our high level of automation and stable, standardized production processes are a decisive quality factor, especially in the production of resistors for the automotive industry. From the receipt of raw materials to the final product coming off the production line, automation is seamlessly integrated into every step of the process. Our state-of-theart facilities feature automated material printers, soldering machines, wire bending machines and much more - all carefully linked together in a flawless clean room environment to ensure the highest level of quality.
We ensure the highest quality
We strive for excellence in quality. After our products are manufactured fully automatic in a clean room environment, each one is thoroughly tested in our automated end-of-line tester. Weight, size, ohmic value, load, insulation and much more are checked to ensure that we always deliver first-class quality. Following this, the resistor is printed on the underside with a thermal paste, enabling easy and swift integration for the customer.
Miba products are built to last
Our resistors are designed for up to 300000 precharge or discharge cycles. Our high quality standards are also confirmed by numerous certifications: Miba is ISO 9001, ISO 14001, IATF 16949 and TISAX certified. Our products are designed to meet the high requirements of AEC-Q200 and are ideally suited for the automotive industry.
Highly reliable PREcharge and DIScharge components for safe and secure operation
Electrically powered vehicles have various electrical energy sources. In addition to the HV-drive battery, capacitors are installed in different modules such as drive inverter, DC-DC converter and much more. The largest capacitor is located in the drive control unit, also known as the drive inverter.

PREcharge Resistors
High voltage systems often use PREcharge circuits to limit the inrush current. If this current is not limited and controlled, it can cause significant stress or damage to other components in the system.
A PREcharge circuit allows the current to flow in a controlled manner until the voltage level rises to a value close to the source voltage before the main contactors close. This precharging normally takes place within one second by limiting the inrush current. To limit the inrush current, power resistors are used in combination with a relay. As soon as the capacitors have reached the operating voltage, the pre-charging relay opens and interrupts the process. The driver can now drive the vehicle safely.
PREcharge resistors thus protect the system from damage, extend the service life and increase reliability.
DIScharge Resistors
DIScharge resistors are used to discharge the DC link capacitors after an electric car has been switched off.
According to IEC 60204-1:2015 and other various EN standards, all capacitors and DC links must be below 60 volts within five seconds of use. To achieve this voltage level, it is possible to short-circuit the IGBTs of the inverter, transfer energy to the electric motor or use power resistors. Power resistors are the safest way to discharge, especially after a crash event. The important
IGBTs are not additionally stressed by the discharge. When discharging, a distinction is made between active and passive discharging. With active discharging, there is an actively connected power resistor to bring the voltage below 60 volts. Passive discharging is carried out with power resistors, that are permanently connected to HV+ and HV-.
Fast DIScharge Resistors
The approach of various vehicle manufacturers is to discharge the vehicle within milli seconds in case of a crash to ensure electrically safe conditions.
In the event of an accident, the vehicle manufacturer must be sure that all the energy is discharged, even if the vehicle is severely deformed. Fast DIScharge resistors are designed for such a case in order to quickly bring the vehicle into an electrically safe state.
